Depends on your state, in mine they are protected and able to be carried if you can.

Yes I've went and bought tard cum with something with a giggle switch just to say I have. Also I'm far from alone using a can on my HD AR because FUCK is 223 loud indoors.

I'm not trying to be funny, but seriously if you've not had to suffer shooting an AR inside with a shorter barrel, it's enough to jar you. Now that's calm chilling at an indoor range. If you figure in HD I'll be woken up at 2am it'll be dark (can keeps from a muzzle flame too) it's not just to say LOL shot you with a title 2 gun, it's so I have some extra chance if indeed I have to pull the trigger and one rule about gun fights, is stack the deck best you can.

When the PSA clone comes out, if at all it's possible I'll snag a suppressed barrel and make my own mp5SD if not I am not sure if and when I'll get it to SBR because I'll probably get the a2 clone due to looks. Again this all comes once it's able to be touched and ordered, I've shot a2/3 and a K. Lovely guns but the geek in me needs it because PSA is making the locking action just like HK and stamped (super good stamping can be really nice HK has insanely nice machine tools and stamps well).

That being said, I'm pressing some 9x19 tonight sipping bourbon. What all gun stuff is going on with anyone else?
It isn't so much the legality (Carry & use of stamped weapons is fine in my state.), but the possible headaches involved if a defensive shooting were ever brought up in front of a prosecuting office for whatever reason. I use an Ithaca 37 as my home defense gun. Loaded with #4 buckshot, has one of those barrel/tube light mounts, and a bead sight -- because if you put anything other than a bead on a defensive shotgun, you're an idiot. I like ARs, but realistically I want to pull the trigger once in a defensive shooting. A shotgun is far more likely to incapacitate on the first shot than an AR will.

I have a pair of Peltors sitting on the night stand next to my shotgun. If I don't have three seconds to clamp hearing protection on my head, then I've fucked up every other aspect of home defense. Ultimately I would like a prosecuting office to read "man defends self with shotgun" rather than "man defends self with suppressed short-barreled rifle." Having a stamped weapon might make them look twice, which might mean more legal fees and headaches for me and my insurance. Fuck that, if I can't handle whatever is happening with seven rounds of #4, I'm either fucking famous or fucking dead.

On the subject of PSA's MP5s, I am extremely eager to get my hands on one to SBR it. MP5s just ooze that 80s and 90s SWAT cool that I love so much. Any recommendations on a 9mm can? I'm also considering building a 9mm upper for a Colt SMG (not automatic) build. 9mm subguns are some of the funnest guns out there to shoot.

I'd think you'd want the earpro even with a can anyway, unless you were fucking about with nothing bigger than .22LR.

(I didn't really use indoor ranges often and certainly not with intermediate cartridges, so whatever.)

oh, I'd love to have both in a self defense situation, but the use of a suppressor, like I said, could have some ugly political/law enforcement repercussions, and just ears for 1 or 2 shots inside the house lower the odds of permanent hearing loss signifigantly.

Both that and I want my neighbors to know there's a party going on at my place and that they're free to invite the police if I haven't already.

Yeah I know reality I'll probably SBR it but one, I'm lazy, two I dunno if you can apply for an SBR on a gun you don't own yet? I probably will want an SBR out of my mp5 tbh. I'll also bite down and do it.

Now to cans, I fucking love liberty https://libertycans.net/ I have a friend that works there and he lets me shoot prototypes and uses me as research (woe is me) but aside my awesome hook up I love how they are made I'm an geek for mechanics and also these are great to clean and tune since I rarely use proper sub sonics I just am trying to save what hearing I have. It's so cool you can stack the can to deal with a larger hotter round or, rebuild it (in seconds mind you) for proper sub sonic and make a whisper out of it.

That being said I also own a gemtech and love it. I've spent time with a lot of cans and I like my hook up and I'm very lucky it's something I get to help direct plan the brand and I find to be the best offerings.

fuck em my state covers it, civil court who cares because legit some nigger judge will allow you to move on someone farted at you... my state will help me thank goodness, I can cite full autos SBRs DDs used in HD situations where the case comes "lol no".

Aside that I try to think realistically, 223 is fucking LOUD inside trust me, if you've ever fired 308 or something else 30 cal indoors I'll be frank it's crippling. The can is to help me keep my self ready for a follow up or engage a second if needed. If I popped my short barrel mosin indoors I'd probably be almost as bad as the sucker on the bullet end. (but not on fire)

Speed helps and I also like to try to be real and I'll be not on my top game etc etc, so trying to put ears on is tricky when I heard my door kicked in at 3am.

i fully support and suggest you do you, but I rather my canned rifle than worry about ears esp when I'm groggy and scared.
 
I'm not big on guns. Not because I don't like or dislike them, I'm fairly neutral. It's just I haven't had all that much exposure to them in my part of the world. That said, I've been watching Forgotten Weapons, a pretty fascinating channel, if I may say so, myself.

Right now, I'm watching a video on a Vietnamese copy of another gun, that doesn't appear to be all that well made. It's still quite interesting to me, though.

Ian inspecting homemade African poaching rifles is my favorite video of his

This morning was my last opportunity to go plinking out in the sticks before the summer heat turns the whole countryside into a blasted 40C/100F wasteland dotted with torrential flash flood zones.

I was trying out some of PPU's modern 175 grain 7mm Mauser ammunition that has unfortunately developed some nasty looking verdigris coating on the brass and jacket since the last time I cleaned it. I was always worried about the verdigris before since I had read that in the Indian Wars, the verdigris would fuse hot brass cases into the chambers of the early trapdoor Springfield carbines since they had weak extractors, but this time I threw caution to the wind and just hoped that verdigris would have minimal effect on a more robust extractor like the one in my Mauser.

And fortunately, the verdigris seems to have no effect on the smooth extraction of spent cases, even after the chamber is getting rather hot. I managed to recover all but one of the spent casings in the event that I can borrow someone's reloading bench sometime, and it looks like most of the verdigris gets stripped off the casings sometime during extraction. I don't think it ended up on the surfaces of the chamber, so maybe it fell back down into the magazine.

By the time I was finished plinking, it was too hot for me to make a thorough search for the spent bullets in the tall grass around my steel plate, so I can't say for sure whether the green verdigris gets completely stripped off the bullet jacket when it engages the rifling. I was very curious about this, because I read in the Boer War-era medical journals, the British Army surgeons kept pulling "poisoned" Mauser bullets out of their dead and wounded, mistaking either copper verdigris or green-dyed storage wax on the bullet for a poisonous coating. The most authoritative surgeon in that war eventually concluded it was the storage wax, but other surgeons and soldiers and Boers mention verdigris so many times that it makes you wonder.

But anyway, I don't regret buying PPU's 175 grain 7x57mm. It's a little more expensive than the 125 grain, but the recoil and kick is still extremely forgiving and gentle, and it's much closer to the historical 173 grain bullet that would have been used by those countries fielding 7x57mm service rifles. For the most historical loading, it would have to be the pre-spitzer round nose-type bullet, but I don't often see new manufactured PPU round-nose for sale at a reasonable price.

there was no "fusing". verdigris is a chemical reaction in brass between copper and salt where the copper exposed to certain acids that contain a salt as an active ingredient and starts a process that separates copper from the zinc in the brass alloy. the remaining zinc is often a paste-like substance bound with the inert salt leftover, and is colored green from the freed copper. this creates a "seal" if the brass is in a vessel with limited volume because the copper and zinc separately take up more room than when still alloyed.

any sufficiently plated (which is most modern chambers) bore, or a bore that is generous at the shoulder, or a verdigris'd cartridge that has not remaining in the bore long enough to continue absorbing atmospheric moisture, is unlikely to "stick" in the bore. an extractor of sufficient strength can overcome geometric changes to the cartridge case, but runs the risk of the weakened case material being pulled apart - creating a broken shell or rim tear.

ammunition is generally cheap enough that it usually isn't worth the time/effort to clean or use corroded ammunition, and with any such ammunition, care must be taken that the cartridge's strength hasn't been compromised.

For whatever reason, most of the verdigris is on the bullet jacket, with only superficial specks of verdigris on the casing, so it seems pretty safe to me. When I scratch away the verdigris on the casing, it looks like there isn't evidence of deep pitting or corrosion to the casing surface underneath.

Should I be worried about the soluble salts in the verdigris drawing atmospheric moisture to the barrel and chamber of the rifle these cartridges were being fired from? I hope it's not like those nasty salts in corrosive primer ammo.

edit: nvm, according to Wikipedia the salts in verdigris are insoluble in water

I'm sorry all, I really don't mean to constantly spam this thread with video links from one guy, but I find him genuinely interesting, and this thing is just too damn cool to not share.

I wonder how many James Bond-style pen guns are out there. Perhaps wildly impractical, but so goddamn cool, even for someone like me. I'll make this the last video I share, because I'm sure I'm annoying some people by doing it. Although I'll happily share more that I find interesting, if folks are interested.

verdigris is on the bullet jacket
most modern (after 1900) bullet jackets are copper alloy. the older the bullet, the more likely it is to have a higher copper ratio in the alloy. and as you mention, while there are several salts that can cause the reaction in copper to produce verdigris, almost none of is hydroscopic since they've already been bonded partially to the copper and that's often nothing left to endanger steel alloy. iron maybe, but not steel.

i've manufactured and sold them - they're an "Any Other Weapon" in the US, and are neat novelty gifts. some jurisdictions have a blanket ban on firearms not readily identifiable as a firearm, but most places have no such ban.

they are largely useless in any sort of "James Bond" situation as at the ranges they would be useful at, you are better served with a needle/stiletto type automatic knife for stabbing, or using a pre-charged air capsule to introduce an embolism somewhere vital such as the neck, armpit, inner thigh, hollow of the shoulders, kidneys, lungs, ocular cavity, or spine (between vertebra). from experience, your target is likely not to be wearing armor in all of these locations at the same time in the situations where an agent can be within a useful range.

all that aside, and ignoring fancy ricin pellet umbrellas, it's far better for plausible deniability to arrange for street crime, a bombing, or an unfortunate accident. frequent travelers roll the dice often and mechanical failure of a critical system, especially in countries where PMCS can be costly (training, spare parts, facilities) or impossible (embargoes on the same) is a very real risk.

Wow, that's awesome, dude! I probably should have a look, but did you feature any of your creations in this thread, or perhaps elsewhere? I'd be curious to see. And I guess all this shows just how much I know about guns and weaponry as a whole. It probably sounds pretty faggy to say that I've, as yet, never fired a gun, but they're just not a thing in my part of the world. It is something I'd like to cross off the bucket list, though, but I'm not exactly tripping over myself to do it. Still, it is on the bucket list to fire a weapon.

I can't help imagining what kinds of spy toys might actually exist. The movie ones might be cool, but I think the real stuff is even cooler. Something I've always been interested in, personally, is physical pentesting, basically getting paid to break into stuff. It's far from gun talk, so I'll keep it brief, apart from saying that there can be some really cool spy-esque toys involved, weapon or not.

Awesome to hear that you made guns, though. I might know absolutely nothing about them, but it's pretty obvious to anyone who knows a little bit about anything at all, that something like that tends to require quite a bit of precision machining and craftsmanship. I think I linked a video from Ian about home/shop-made guns, before. Some of them were mind-blowingly simple, and probably quite literally mind-blowing if you were to try to use any sights they may have!

EDIT: Yeah, this video is one of two I'm thinking about. The other one is linked below it. And again, I'm sorry to overshare. I just find the stuff extremely interesting.



I think most can agree that it's pretty astounding how little material and skill can make a lethal weapon, or at least one good enough to cause serious injury.

i've provided firearms for television and film a couple times, mostly films and some "direct to video" type productions. some recent ones were the "blockbuster" category though. the vast majority of my business is contract armory duties (service/support, spare parts, training, accessories and supplies, et c) for government agencies that are too small or too remote to bother with constantly shipping things back and forth or dealing with locals who might not be familiar with their gear or who isn't manufacturer trained/supplied. last year i expanded into manufacturing ammunition as well.
I can't help imagining what kinds of spy toys might actually exist.
most fancy "spy" toys i've worked with were more ingenius than complex. like using a decorative metal dish as an amplifier and guitar "art piece" to pick up spoken conversation (which vibrated the strings on the guitar minutely, that were reflected and amplified by the metal dish to the conference room window) that is seen and examined via laser microphone through a glass from a skyscraper on the other side of a street (this was in the 80's).

[...] I think most can agree that it's pretty astounding how little material and skill can make a lethal weapon, or at least one good enough to cause serious injury.
the most common problem that expedient firearms face is the manufacturer not understanding how to manage the peak pressure impulse of when a cartridge is fired. it's why a PVC pipe shotgun works very well, but an all steel pipe handgun is a grenade waiting to happen. firearms are not generally very complex or technologically advanced objects; however if you don't understand mechanics very well, you're sure to have a bad day.

This is the old edition they are now currently working on the FGC 9 ( Fuck Gun Control 9). Being made by deterrence distributed on twitter. They have been able to 3d print glock mags (you can print them for about 3 bucks a pop) and nylon print AR lowers n mags (which is much stronger then anything previously) .

The new FCG is like the shunty in the video, The only non printable parts are the screws n pins, the barrel and the bolt (all available at a hardware store). They even developed a way to rifle the barrel using ECM with common parts.

I grew up around firearms. Never been a huge fan of higher caliber ones, but I like the simplicity of 9mml and .22. Got to fire an AK-47 my dad bought a few years back. Don't formally like rifles, but it was fun.
