So, I'm finishing up a 8" suppressed build on a transferable lower. I just got it running about 100% with and without the suppressor but needless to say, it's next to impossible to keep your eyes open with all the gas I'm getting in my face shooting this thing full auto.

What's the best option for a charging handle here? It seems to be the go to option for cutting down gas to the face. I've looked at these three...


Anyone have any experience with any of these or cutting down gas blowback in general? I'm open to throwing high temp silicone on anything along with drilling vent holes into the charging handle as well if these three choices are gimmicks, seems to be what a lot of people are doing. Overall just looking for the best option.

So after much research and thinking I believe I've found my solution.

Fist off, the gas is primarily escaping from between the BOTTOM of the charging handle and not to top. Most of these charging handles only attempt to block gasses from the top and from what I can tell only the PRI one even tries to vent from the bottom. So issue number one is perusing a product that was flawed in design from the get go.

I'm going to do some experimenting with my mill sometime in the next few days. Along with some high temp silicone on the top (to ensure all gasses are directed into the newly designed bottom) I'm going to try and mill a series of angled trenches onto the bottom of the charging handle's rear.

I'm using PRI's idea as a base. However I'm going to enlarge it in both depth and width and make it vent out both sides to hopefully work better. It should also hold up to abuse better than a series of holes.

A freakish success!

Cuts the amount of gas I'm getting in my face by at least 60%, didn't even put silicone on it. Not bad for five minuets of labor.

I think I can improve on the design as well, give me a few weeks and I may have something worth mass producing.

Cartels coming in aren't usually bringing weed although they do some. Most weed is home-grown or bought at dispensaries (And then dispersed out in smaller sales)

Weed was also never a gateway drug, this was common thought thanks to a massive propaganda campaign in the 60's.

I was in my first ever "selfie" today and shortly thereafter decided that my next selfie was going to be shot with a 0.45, the next thing that popped into my head was an amazing idea for the latest must-have rail mounted tacticool accessory. Its pretty simple, its a mirror that flips up behind the front sight to aid suicide artists in aiming. Also included is a push rod that when folded into place helps people using their rifle at this odd angle reach the trigger.
I call it "Custer's last accessory" after a book I read called "Keep the Last Bullet for Yourself" and I'm guessing that every edgy kid with an AR is going to want one, what do yall think?

Y/N? Suggestions? Around $1000 sounds fine to me. (Willing to go higher if there's something awesome.) I'm not super into long range... but want to get something pretty decent. (Don't think I'm into it enough to do Nightforce or US Optics.)

The shitty thing is, my local range only goes to 200 yards. I hear there's a 1000 yard range in WV, a couple hours away. One of my coworkers has some property up in PA with some range.

File 148349373285.jpg - (309.77KB , 1600x1200 , compass M1950 lensatic compass 1.jpg )
After WWII the Army incorporated induction dampening into the M1938 design. Induction dampening is a beautifully simple concept. It takes advantage of the inductive magnetic field generated between a swinging compass needle and a highly conductive but non-magnetic alloy like copper. When a magnetic needle (or bar) is placed inside a cup made of copper and the needle swings (oscillates) that movement causes a slight magnetic eddy current to form. When the needle swings to the left the eddy current pulls it to the right. When it swings to the right the eddy current pulls it to the left. The eddy current is self-canceling; as the needle oscillations decrease the eddy current strength decreases and very quickly the needle settles down and is aligned with magnetic north. Simple, elegant and effective.

However, by the late 1940s the Army decided it was time for a whole new design. The Army took the best functional elements of the M1938 compass – the lensatic sighting design and the combined degree and mil scales on the compass card – added induction dampening, a needle lift device, a much larger sighting lens and a larger thumb loop and placed it all in a beefed-up waterproof aluminum housing. The resulting compass was designated the M1950 Lensatic Compass. It is a rugged, versatile device that has remained in use with the US military for over 60 years, pretty much as originally designed.

- M1950 Lensatic Compass This particular compass was manufactured in February1953 by the Marine Compass Company out of Pembroke, Massachusetts. The cloudy dial cover is the result of the plastic aging. Remember, this compass is almost 60 years old!

Sometime in early 1942 a photographer asked General Patton to strike a pose doing something dramatic. I don’t know who’s idea it was to have him pull out his compass and shoot an azimuth to a distant point, but the resulting photo is interesting. Patton is standing beside his early M3 Stuart command tank and decked out in full battle regalia – tanker helmet and goggles, tanker jacket, binoculars, signature pistol at his side and an M1938 compass in his hands.

  Anyone tried the Leupold VX-6 scopes?


I'm thinking about getting a variable mag scope for my 16" AR for 3-gun. I was looking at the Vortex Strike Eagle 1-6 and then got on to SuperSetCA's video here. (Fantastic production by the way.)

Any thoughts on this model or similar ones? 1-6 vs 1-4?

I've got pretty good eye sight and have been using Aimpoint H1 reddot thus far with no issues, but the furthest I've shot is inside of 100 yards. I'm just thinking for future use when I go to an event that supports longer range.

Looks like I'm not the only one with those concerns.

I do have to admit that the DR, on a purely performance-based evaluation, does seem like a great optic. When I think about using variable magnification optics like 1-4s or 1-6 or 1-8s or even that 1-10x by March Optics, how often would you dial between the minimum and maximum?

I mean sure if you're lazily plinking away you might dial something specific but within the hundred-whatever yards it'll be on 1x, and past that I'm pretty sure 99% of the time, the user will just rip that sucker to max so they can get a bead on quick. The Elcan at that point seems most logical, as it removes pretty much what you'd never use in the first place for a "fighting" optic. Makes me wonder if they make some sort of condom you could stretch over the Elcan to keep shmoo out so it doesn't go all sidewards if you get sand in the moving bits.

Either way I go back to >>102005. You could even streamline it further with a micro (pistol) red-dot and a fixed power scope.

tl;dr I hope to see optics come out in the future that are like an Aimpoint H1 that had sex with a Specter DR or a 1-8x S&B Short dot or something. Something bomb proof, killer battery life, throw-lever from 1x to whatever x.
>> No. 102117 ID: cad48c
I've got a SpecterDR 1.5-6x on my SCAR 17. I'm reasonably pleased with it, but that price is a pain in the balls for sure. My biggest gripe is that, while the thing seems pretty sturdy, for that kind of money I expect ELCAN to have a warranty like Vortex does -- it doesn't matter how it gets fucked up, a replacement gets sent. From what I can tell the warranty is pretty much bog standard.

Practically speaking, with the 1.5x I'm pretty happy to use it as a scan optic, and the 6x works good for precision. I'm pretty pleased with the reticle, and the illumination functions work well, though the full-on crosshair illumination is a little funky in that it doesn't actually illuminate the entire thing like one might expect. Not really a problem though, just odd.

Despite the fact that it's got a dot, picking up up fast will take a lot of practice and muscle memory. I wouldn't feel good snap shooting with one, but it does have basic irons on top and you can always add a red dot. I perched a little Vortex Venom up there, but haven't had a chance to play with it much since. One thing to note about the irons is that they're pretty low, so the front flip-up lens cover pretty damn near obscures it if you go that route. You can thin it out with a Dremel and have it workable, but frankly I expect better on a piece of kit this pricey.

In terms of logic, it looks like you're kinda on the same page I am. Fuck it, it's either lowest or max power, the middle range is almost never used. May as well make the transition fast and easy.

Long story short: It's a good optic, I like it. Is it $2500 good? Ehhhhhh... at that point you really need to play with one, IMO. Personal preference is what's going to decide that. Unfortunately, they can be a pain in the dick to find. Would I buy mine again? In the same circumstances, yeah, I probably would. It was a treat for myself and funded entirely by overtime cash worked explicitly for that purpose. I'd be a hell of a lot happier at a better price point or with a better warranty though.

I have the strike eagle 1-6x

Pros: Awesome reticle, red dot feature is good and easy to use, eye relief/picture is better than scopes anywhere near that price range (But not still GREAT, just good), mine came with free caps too which is a plus, and obviously the price is great

Cons: Heavy, the dial to turn magnification is rough/small/slow to turn, eye relief changes as you change magnification is dramatic enough to require you to change your head position (But this is also true of other 1-4 or 1-6 scopes in this range)

IMO it's the best BUDGET 1-6x optic. It leaves a lot of "quality of life" features to be desired, but it knocks all the standards out of the park. I've had experience with a VX2, a burris, and a few other 1-4 or 1-6x scopes and I found this to be the best. Grab it on sale for $230 or so, and you can't go wrong

>Jerry Michulek(sp?) swears by the strike eagle and uses it in competitions, he keeps it dialed up at 6x and uses a vortex red dot at a 45 degree angle for the 1x shots

Interesting. I'd like to see if the next generation of v-mag scopes will come down in price thanks to Vortex.

I'm looking at an 18in barrel from APOC Armory, and from what I understand one needs different buffers for different barrels. Do different buffers preclude you from using different stocks?

A few questions about vented barrels...

If you have a vented barrel, with a vent very close to the end of the barrel, is it not possible that this will adversely affect the stability of the bullet as it leaves the barrel? After all, there's a sudden gap in the rifling and then it starts again? People keep harping on about how the crown area is possibly the most important barrel part accuracy-wise?
Is the area where it restarts given special attention to ensure the rifling engages more gradually when they vent a barrel like that? Or is this a non-issue and I'm overthinking this?

(ignore the silly dual 1911 abortion I'm using as an example)

New and interesting malfunction from Kel Tec
7 posts and 2 images omitted. Click Reply to view.
>> No. 102060 ID: 6057a8
I assume it was extraction/ejection. It looks like the round went off, extracted, but didn't leave the rifle.

I tried an SU-16 and it cycled like it hated life. Not sure why the case didn't fly out as I would expect, but with a rifle that cycles as violently as the one I tried (assuming mine was a regular example, I don't know, haven't shot other examples), if the case doesn't go a mile out and slips off the extractor early, the bolt coming back and closing on the empty case at just the right angle could crush the case like that.

Just speculating, OP should return and tell us more about it.

It kinda felt like the gun was like "PARTY HARD YEAH" in that "I don't expect to live that long since I'm made of cheap parts, but I'll do my best until I spontaneously disassemble" kinda way.

So I'd expect it to work with no issues in any situation with any ammo until all the guts shit out from any available orifice.
