  A while ago we had a thread about high-speed photography and such. I think my friend and I took some curious pictures today, not sure how interesting they will be, but it was enlightening to learn what a DSLR could do in this kind of situation.

The camera in question is an Olympus E-510 with a Zuiko 14-58 F2.8 lens, a little dated and nothing special to begin with. In the midday sun, we were able to get a fast enough shutter to be able to capture bullets. Because of how these kinds of shutters function, the bullets are still quite blurry and faint but they're still visible.

Video is related to explain how the shutters typically work, to explain why the bullets weren't exactly as crisp as one would expect from shutter speeds of 1/4000th of a second, and why they're blurry in a slightly asymmetrical way due to a "rolling shutter" effect.

Also these guys shooting a giggle-switched AR-15 was adorable, great footage as well.

Long time no see, lads

How hard would it be to rebarrel my CZ82 in 32ACP assuming I can get an appropriate CZ83 barrel? I know I would need a hydraulic press but I gave one now so I’m curious what other tools I would need

It's better to just buy a CZ83.
That's how big a hassle it is.

You might get the old tube out with no fuckups, and you might get the new one in as well as the old.

"Please don't". Just buy what you want. This is not a 1911 where you can mix and match.

Sup, I'm going to be repairing this lower which had a third hole drilled for an illegal sear conversion. I need it to be able to survive an ATF inspection. It's a classic Colt lower, so trashing it is out of the question. I've watched many videos showing how to repair the hole, and I think I've got a workable solution.

Not really, been out of the business too long.
I'd suggest walking it through a SAR West show, and asking the folks at Lone Mountain, or looking for "Kenton Tucker", he helps run the Big Sandy and might know a solid source.

I already own 3 .45s (SA 1911, M&P Midsize, Shield 45) and reload for it. Mags aren't too pricey and easy to come by. I see mixed reviews on the trigger but it would be something different in the collection. Thoughts for the price?

Decided to buy one of these through Aim. Arriving at my FFL on Monday. I finally decided on trying a 9mm carry gun. I'm unfortunately limited to 10 round mags instead of the factory 12, but MecGar makes 10s and relativity cheap on eBay. Not Magpul GL9 levels of cheap, but good enough for my now low budget.

Any recommendations on holsters? Also how can I tell if I need to replace the recoil spring?

I'm hasgun again, but not the one I want. My k-frame is gone. Somewhere between my idiot sister-in-law and her idiot baby daddy, that one was "lost." Fuck, I hope someone pawned it. Better than losing a fucking firearm.
Anyway, the one returned to me was my back-up/fuck around piece, a Jimenez Arms .22 I purchased new a few years ago. It didn't work that well. I took it to the factory (they're close), they worked on it, and surprise! No difference! From what I've read online, the thing to do is sand and polish the innards, and I figured that's worth trying, but a lot of variables there. What grit should I use? Should I just use steel wool? What kind of polishing compound? Feed ramp and slide rails of course, but anywhere else I should hit? Seems like it could be a fun little project, and if I completely fuck the thing, who gives a shit? It's a Jimenez.

So I've been putting together an 20" upper and optic combo with the intent of making a DMR type of gun. I've got the upper and optic sorted out but my bipod choice is giving me trouble.

I went with the BCM SS410 20" with the SAM-R profile barrel and their M-Lok handguard because I've standardized on M-Lok. I went with the Magpul bipod. My problem is that the barrel is thick, along with the gas block, and/or the handguard is so trim that there isn't enough room between the inside of the handguard and the barrel or underside of the gas block for the bipod to lock it in. Trying to move it back to a slot clear of the gas block and I run into the problem of the barrel itself being so thick there isn't clearance between the M-Lok attachment screws.

I know Vltor makes a two-piece bipod that could possibly attach on the sides but they aren't M-Lok. Does anybody have any other suggestions for bipods that are M-Lok attach and they mount to the sides of the handguard instead of at the bottom?

Another shot of the VLTOR modpod legs on the SCAR 17. Back when bullet buttons were a thing in California.

The 17 is currently a bolt action rifle (with gas system removed) until I can fix the stock, wrap the pistol grip, and swap the FSC for a non flash hiding muzzle brake.

Not even. I had some airsoft guns and accessories by them when I was in middle school circa 2004. And even they couldn't hold up to walking around in the woods for a few hours every weekend in the summer.

But, I have a morbid curiosity about their US made accessories now...
>> No. 108989 ID: 419c96
Thought I'd let y'all know I did a bit of a work around. Rather than going with an airsoft bipod or shelling out £330 for that neat top-mounted model, I trimmed down the screws on the M-Lok attachment so that they don't contact the barrel. I still had to use the next slot back from the gas block because the little rotating piece itself is too thick to fit between that and the handguard. While it's not a whole lot of clearance between the barrel and the screw, it's clearance.

Does anyone know where I can find a 30mm cantilever scope mount lower than the typical AR height? They all seem to be around 1.4" - 1.5" from the rail to the CL of the optic. I was using the optic from my AR while I waited for a scope to come in, and the LT-104 it's in is really too high at 1.5". No one seems to make a lower cantilever except super expensive ones like spuhr, nightforce, etc.

I've been collecting information regarding Japanese small arms cartridges for a few years now, trying my best to sort out all the confusing Type designations. I still consider this a work-in-progress and I am still hoping to fill in some f the gaps in my collection.

Japanese Handgun Cartridges

The first modern handgun adopted by the Japanese military was the Smith & Wesson No.3 Russian revolver. The Type 26 officially replaced the aging Smith & Wesson revolvers still in service in 1893 but some of the older .44’s still remained in military stocks until the end of WWII - though most of the ammunition had degraded to the point of being nonfunctional. In addition to the .44 S&W Russian, there were also privately purchased handguns in military service chambered in 7.63x25mm Mauser, 7.65x21mm Parabellum and .32 ACP.

1- The .32 ACP was likely the most popular foreign handgun caliber in Japanese service. This was used in private purchase Colt, FN and Mauser .32 caliber pistols as well as domestic designs like the Hamada.
•Average loading used a 71gr bullet with a muzzle velocity of 905 fps.
2- The 7mm Nambu was introduced around 1902 for the Type B ‘Baby’ Nambu pistol. It was produced until the end of WW2 despite the relatively low number of pistols made for this cartridge.
•Average loading used a 56gr bullet with a muzzle velocity of 1050 fps.
3- The Type 26 revolver was the only handgun to use the 9mm Japanese revolver cartridge. It was adopted in 1893 and served until the end of WWII.
•Average loading was a 149gr bullet with a muzzle velocity of 639 fps.

4, 5 - The 8mm Nambu was used in the 1902, 1904, Type 14 and Type 94 Nambu pistols. It was also used in the Type 100 submachine gun. There were a few experimentals such as the Hino-Komura pistol and the Type I and Type II submachine guns. Most bullet jackets were cupronickel but in WWII the shift was made to gilding metal jackets.
•Average loading used a 103gr bullet with a muzzle velocity of 984 fps.

Screenshot from World of Guns on Steam. The Beretta trigger bar is pulled forward by the trigger and trips the sear. The trigger is a lever that gives your finger some mechanical advantage to pull the trigger bar forward.
>> No. 108949 ID: 9dcda2
  FF to 1:37.

The sear bar on the Type 94 directly operates the striker, and pivots inward, where your holster could push it in.
>> No. 108950 ID: 9dcda2
  FF to 0:40

The Luger actually has the same issue, except that the sear bar is covered by the trigger side plate in normal operation. But if left loaded, it can be fired with the slide and frame separated.
