Gun Review: FN M249S Semi-Automatic SAW
FN Manufacturing has been cranking out weapons in Columbia, South Carolina for the U.S. military for years now, winning contracts for everything from the infantry man’s friend, the M4, through the explosively fun M240B. Up until last year the civilian side of the house had been forbidden from offering civvy-legal versions of their military guns — the closest we’d gotten was their FN-15 rifle released in 2014. But last year all that changed and the “Military Collector” series was born. Now the average American can purchase a proper M4 or M16, spec’ed out exactly the same as the military gets them (minus the full-auto setting, no matter what you may hear on MSNBC). The most awesome offering in this collection so far: the Military Collector M249S.
The original M249 was developed in the early 1970’s. The U.S. military had briefly fielded the Stoner 63 light machine gun (LMG) in Vietnam as a way to provide front line troops with a lighter machine gun that was easier to maneuver through the thick brush and jungles of the area, eventually looking to replace the much heavier M60 and M2. While the Stoner design had worked, the military wanted something better. A Belgian company called FN had been in development of their FN MINIMI LMG for a few years by the time the U.S. decided to look for a replacement, and in a head to head competition in 1980 their design beat out both H&K (HK21A1) as well as Colt (who just thickened the barrel on an M16 and called it good) for the contract.
Something to note about the M249S is that it is a bit different than the other offerings in the Military Collector series. Where the Military Collector M4 is identical to the as-issued version, the M249S is instead a mix-and-match version that has been cobbled together from different eras of the M249 to create the most visually appealing and enjoyable example of the firearm possible. The purist inside me is complaining, but the execution doesn’t leave much room for argument. http://www.thetruthaboutguns.com/2016/06/foghorn/gun-review-fn-m249s-semi-automatic-saw/

  Or you can make a reproduction of the old hand-cranked Gatling Guns. I have seen 1/4 scale models that fire .22 LR and full-sized ones that fire .45/70 Govt.
Reproduction 1877 "Bulldog" Gatling Gun https://youtu.be/ildteJbZ9Jw
Thanks to a friendly collector, we had the chance to take out one of the new, gorgeous reproduction 1877 Gatling guns being sold by Colt. It's a near-exact replica, with the added feature of being able to crank backwards to safely clear any loaded cartridges out of the action. Being a Bulldog model, it has 5 short barrels (18.25") chambered for .45-70, enclosed in a full brass jacket to keep the action clean. Colt claims it will do 800 rounds/minute, but we got it going a bit faster...

Thanks to an interesting quirk of US gun laws, the Gatling is not considered a machine gun - so anyone who can possess a bolt action rifle can own and shoot one of these. The crank handle is considered a trigger, and each partial turn fires a single round. Since a single discrete motion doesn't fire multiple rounds, it's not subject to the registration and transfer tax of a machine gun under the NFA.

  M134 Minigun: The Modern Gatling Gun https://youtu.be/rIlwHT4IdRc
The General Electric M134 "Minigun" is essentially an electrically-powered Gatling gun - the conceptual operation of the gun is identical to Dr. Gatling's original creation. What has changed, however, is the chambering (it's in 7.62 NATO), the power source (an electric motor), and the feed mechanism (belt-feed using M60 links instead of the Gatling's Accles, Broadwell, or Bruce feeds). The weapon was a scaled down version of a 20mm rotary powered cannon devised for aircraft armament after WW2, hence the "mini" name. It was used primarily as helicopter armament, although it has found its way only ground vehicles as well. Firing between 3000 and 6000 rounds per minute, the Minigun is ideal for aerial engagements where the gunner only has a brief moment on target and needs to fire as much as possible during that moment.

It is a truly awe-inspiring weapon, and quite an experience to fire! In addition to destroying a truck with it, we will look at disassembly and functioning of the minigun - the delinking mechanism is really the most complex part of the weapon, and a very interesting device.

It's awesome on a single action 'cause you can let the recoil slip the gun up so the hammer's right there for re-cocking. I don't really think that's really super cool for anything that's not a single action revolver, but hey whatever floats your boat.

It is true but they aren't a very good choice for defense, you could use one for intimidation or to hurt a dude in light clothing but a can of pepper spray/CS is probably better both at stopping a threat and being non-lethal.

Traumats have a nasty reputation of being pretty random in terms of their damage. You can shoot someone, he won't give a shit and still beat you up or you'll shoot a guy in some weird spot without any intention, he'll die and then you're fucked.

As for actual weapons, I don't remember it well but from the top of my head you can get them for sporting purposes like bullseye, IPSC, etc but you normally don't care about that because I don't think you get to take those guns home. Maybe they changed it, I'll look into it.

Or you can get a smoothbore license. It will require medical papers from your local prevention center that say you aren't a registered nutter and/or drug addict, papers that say you've had gun lessons, a fortified gun case in your residence, doesn't have to be a proper gun safe but it's better if it is one. Your local beat cop will have to OK the thing before you can buy your gun, iirc. Then you have to submit the gun to the police for them to inspect it, fire and register. Then you can have the bloody thing to go hunt or shoot bottles in your country house backyard.

Play with it for a year then go submit it again to be inspected and fired, you have to do that shit every year. After 5 years of owning a smoothbore you can get a rifle permit, the procedure is similar, iirc.

I've probably forgotten a bunch of steps but the whole thing is an huge ordeal costing you time and money so many people don't bother but then again, many do.

Can you possess pistols (other than rubber bullet pistols) in Russia?

Special restrictions are imposed on the circulation of civilian weapons. Prohibited firearms are those with a cartridge capacity of more than ten bullets, those that can fire in bursts, those with a barrel length of less than 500 millimeters or an entire length under 800 millimeters, and those that can be shortened to a length of under 800 millimeters without losing their shooting capacity. Rifled-bore sporting guns and pneumatic guns with a pumping power of more than 7.5 joules and a caliber of more than 4.5 millimeters must be kept at shooting ranges. https://www.loc.gov/law/help/firearms-control/russia.php#Acquisition

Not realistically. You either have to get a commendation pistol, or get an antique one or a replica of one. It has to be a model produced before 1899 and it can't use a uniform cartridge.

You can also go to a shooting range and give them money for a pistol that will be reserved personally for you at that range, but you can't carry it or keep at home.

It served us well. It was one of the most relevant fighting rifles built in the 20th century, but what about the 21st? My goals are...

1) Rebuild a M1 and make it mission capable for another century without anyone realizing what just happened.
2) It must adapt to an ever changing world that it was not meant for.
3) Accurate? Yes
4) A change in weight and balance
4) A lie...
5) Must use modern materials as much as possible
6) Of course reliable
7) Make old people happy- or maybe not.


All questions, comments and advice welcome. So it begins.

>>Range trip writeup please.

In my hands in the prone it shoots under 2'' at 100 meters with iron sights.

At 200 meters it still seems to hold under 2'' width groups. In picture related I was probing a bit on the elevation by changing the point of aim (thought I was missing). As you can see all 8 rounds hit the target and stayed in a narrow strip up the target.

Took it out a week ago at a semi-optchan-ish shoot. Blew up 30lbs of tannerite at 200+ meters on the first shot. Mammoth witnessed an oak tree historically.

Overall a solid shooting M1. Very accurate for what it is.

I didn't relax when daddy was elected and took advantage of everyone trying to slim down inventory. Vehicle AR pistol project is wrapped up, have a good stash of 5.56 and lancer/magpul follower GI mags. If I wasn't broke as fuck I'd be bulking up my weak points like more tourniquets/medical supplies, lighter armor, etc. But that's regardless of current events.

AR sales have picked up, but not really anything crazy. Hate to say it, but they've been really shitty people and universally pretty fucking stupid. Like "I'm anti gubmint,me too but I also don't know how to use computers so I'm never quite sure what's happening around me and am angry about it". I literally had someone ask me if I had heard about "this shooting in Las Vegas" today and they wanted to know which AR to buy before they get banned.


I'm mainly just sick of the hordes of people looking for bump stocks. I had a little fun playing dumb to what they were with some loud snaggle toothed fuck today. Pretty much the equivalent of "no speak english" Anyone who brings up bumpstocks is a huffpo writer. Anyone who asks if we have one for sale is a well trained huffpo writer.

  When I had sent it in, I'd subtly asked for black parts to replace the odd color on my used RFB; I received it back with an entirely new assembly - in the same damn color. So I asked, since I already have the necessary screws/pins, if I could just buy what I needed and replace it myself.

>Technically you can just buy the set of polymer gips and handguards, but i would not suggest going that route. Just to try and put it into perspective, we have two technicians who's only job is building RFB grips, and even with the special tools and jigs sometimes they have problems getting them together. The price for the complete assembly is $498.

Hmmmm...
The total cost of parts, w/out S&H: $139.00

  Ah.

>Dan Love is best known for his firearms engraving for other gunsmiths like Hamilton Bowen. He also provided Texas Longhorn Arms with the drawings of the No. 5 grip frame that he had personally acquired from Elmer Keith.

>Love has been infatuated with George A. Wilson's prototype target pistols for decades. Back in the 1980s, he wrote the various gun magazines that had previously featured the Wilson pistol in the 1960s in hopes of tracking down the current owners. However, it was decades too late for anyone to really help. Several years ago, he even started posting to Internet gun forums in an attempt to track down the pistols. By this point, he had already begun work on his own design, but he wanted to see exactly how Wilson had configured certain parts.

My mom lives by herself, tending to her own homestead in the woods of Maine. My mom is old, sick and weak. Between being treated badly by bosses at farms she's worked at and the fact she's come down with a couple different illnesses over the years means that her joins and her strength have been ruined, she is just too weak and sickly to use most firearms. Which is bad because of her neighbors.

She has weird neighbors that have moved into the woods around her over the years. One dude is a nutcase who beats his wife. One is an aggressive retarded asshole with a confederate flag on his house and tries to run people off the road with his jacked up truck. One is a real creepy tall dude with no teeth and no sense of personal space. All of them seem fine with roaming around my moms property when she is at work. Someone has filled my moms locks with crazy glue, twice. Someone also went inside and redirected a dryer pipe in my moms house to spew carbon-monoxide into the house instead of out of it.

So what the hell kind of gun does one get a weak old lady in a situation like that? I don't feel that she's really safe without one, but I am currently out of state going to school so I can dig my family out of poverty, so I can't defend her myself. So what the heck do I do then? A tiny .22 pistol would be something she can manage, but I know that you can't/shouldn't use .22 for self-defense. But it does not seem like there is much between .380 and .22 other than uncommon rounds that are somewhat hard to find, costly, and are fired from pistols that are costly themselves.

What is your opinion?

TL;DR: Sick, weak old lady who is even weaker than your average old lady and lives alone needs cheap, small cartridge pistol to defend against violent, threatening retards. Options?

A phoenix arms hp22 was my first gun, and I still have it. About 4k rounds through it.

Honestly, if someone made a not-pot metal or retarded safeties version I'd totally buy it.
This is one of those guns that you know you shouldn't like, but somehow do. The limiting factor of it's accuracy has always been me, not the pistol. The trigger would probably be considered not great, but for me it fits my hand well and the and the take up and wall end up being nice for target shooting. I'm able to pull the trigger on the gun and have it remain completely motionless (which is more than I can say for my fucking Kahr).

One thing to watch out for is to make sure the roll pins are flush in the frame, filing them down if you need to. Especially the one just under the slide on the right side, partially covered by the grips, which will rub against the slide.

Another thing you'll need to do if you shoot it with any frequency, is to always inspect it for cracks, I hear that particularly the slide is where failures most often occur.

As far as reliability goes, my impression is that it is as reliable as the ammo you feed it. If you put in cheap 22lr, you'll get the occasional stovepipe or hangfire.
It wouldn't be something I would outright recommend for self defense, but it will always be superior to nothing.

With an empty mag extended mag and the long barrel it weighs 22.6 ounces. She may have issues pulling the slide back or cocking the hammer. ALG's extra slick oil or grease can help, but she'll still need to exert a fair bit of force as with most hammer based guns.

True! You can get better boom from .22 Long Rifle than the diminutive .25 Auto.
Even the .25 Jap (6.5x50mmSemi-Rimmed Arisaka) was seen as being too light in the ass, but this round was used in early experimental assault rifles such as the Russian 1915 Fedorov Avtomat.

Any of you have these videogame guns?

Also, what other revolvers are there that were intended for modern service and were more or less successful than R8?
I know the French used one and picrelated .500 Russian tanker anchor can be found on the net but it probably never went anywhere.

Man, I went to the south entrance to check out the noise and I swear it was a jazz trumpet I heard. Investigating further, I saw these eyes light up in the darkness, and then this dark black face. I swear it was Miles fuckin' Davis right there in the tunnel! After I shit myself, I had to didi mao the hell out of there!

That's actually really good logic.

Strategic as fuck.

So I've been shopping around for a CZ pistol for a while now, but some of the finer points escape me between a few of the models. There's the Shadow, but it's different than the SP01 Shadow, both are different compared to the Shadowline, and so on. There's the Shadow Tac II, then stuff like the 75 Tactical Sport, and then Czechmate, so what the hell is this clusterfuck about? Their website isn't much help being slow, messy, disorganized, and not exactly easy to compare model to model.

I'm particularly interested in the Shadow and Shadow 2 pistols, and I am planning on installing an SAO flat trigger into whatever CZ pistol ends up being chosen. It'll be for range pew pew so practicality isn't exactly high on the list and I have no trouble with racking in-frame CZ slides. I would appreciate any info on these things, especially shit that isn't exactly obvious or often covered in reviews/product descriptions.

Then it hit me.

I don't have a sine bar.

It took a little while but I simulated one, should be close enough for the stuff to be angled right. I'll also take into account the front and rear sight line angle in comparison to the slide top.

>simulating a sine bar
It looks a little funky because we all have to remember that gage blocks are only precise in flatness, parallelism, and thickness. They are pretty much useless for squareness and perpendicularity, so the two pins have to ride on blocks sitting correctly, but then you have to separate the pins precisely by putting another block between them. With a 2" block separating the two pins, the error due to the block not being square should be extremely small, as it'll only be as much as the difference between the hypotenuse of a triangle with a long leg of 2" and a short leg of something like 0.008". I can live with 0.000016" error on that.

If the setup was not made like this, the error might be much greater, hence the explanation and why it's a little like an upside-down sine bar. Either way, it should work.

Using a micrometer to measure the pin diameter accurately, we can find the exact distance between the two pins, then use the aforementioned gage blocks under the pins to meet the angle of the top of the slide. We then compare the slide to another set of wrung blocks just to check, as comparisons are quite a bit better than using the little dial on the height gage.

Once I finish this I'll be able to ensure the cuts are made at the right place, right depth, and right angle so I don't end up mangling my pretty Shadow 2.

I don't mind hearing your thoughts about this to make sure I haven't forgotten anything obvious.

Gotcha!

good digitals > good dials > vernier > cheap dials > feces > shitty digitals

You referring to only calipers?

Because my job gave me a Mitutoyo 8" dial caliper, and I own the 8" digimatic seen earlier in the thread.

I used both the dial and digital Mitutoyo calipers daily for a while before going back to all digital, I just don't see the appeal of the dial calipers. They are also more sensitive to dust, and the "feeling" from trying to measure things with consistent pressure is much harder with the rack and pinion physical dial than a smooth digital.

Dial just doesn't feel a nice, doesn't read as quick, and doesn't really do any easy incremental measuring (if that's what you meant by comparative measurement). With no downside with digital, I can't see any reason to use a dial.

Keep in mind I'm comparing dial calipers to the Mitutoyo Digimatic and not other digital calipers, this is a very important point as I have not liked many other digital calipers.

Digital calipers are offered in coolant-proof variants, but I stuck with the regular digimatic as I liked the buttons and feeling of it better. I find it's much easier to keep the calipers out of coolant rather than keep dials out of ambient dust and small airborne debris.

Measuring tools are obviously subjective, and I have known amazing machinists that used tools I didn't like and obviously made good parts, so it's yet another proof of the million ways to skin cats in the manufacturing industry.
