EDIT:I have found some very interesting information on True Velocity's website, one of the failed contestants for the NGSW contract.

• MILITARY AMMUNITION: 7.62x51mm NATO; 5.56x45mm NATO; .338, 50 BMG

• COMMERCIAL AMMUNITION: 5.56x45mm, .308 Win., 6.8TVC

I was most interested in the polymer ammunition from the NGSW program, so that definitely has my attention.

My biggest question is if it can be used in rifles with fluted chambers, like a CETME.

• MILITARY WEAPONS: RM-277 Rifle and Automatic Rifle

Now THAT definitely is interesting; as it was also the system which I wanted to know more about, and secretly hoped would win.

That was very informative. It feels like modern camera microphones don't capture sound in the same way which old ones do, the *WEEEOOOOOW* noises from that thing coming over from the distance is like good old action movie/cartoon goodness.

The first time I got mortared, the fact that it doesn't sound like old-movies incoming somehow still surprised me; and same thing with the hiss of an RPG. I literally just stood there because the sound didn't register in my brain.

That's how you know the muzzlebrake is working. I think you can get more obnoxious though, something akin to the Hungarian AK muzzlebrake.

That would be hilariously awesome, though the AK-74U kinda needs the muzzle device/booster. But a howitzer-like brake on something like the Micro Draco?


RE: the Prison Thompson

Oh, cool, what kind, an earlier blish-lock one or one of the later blowback ones?

Late model as far as I can remember; it belonged to Dragonman. I used to spend so much time & money on his range & in the store, eventually one day he asked me if I wanted to shoot them, probably after he got tired of hearing me pine for it, or at least the live-fire experience.

It was either that, or something earlier in the day pissed him off & he was waiting for an excuse to go outside & blast.

I know this is a firearm thread, not an airgun thread. But I figured it counts, close enough anyway because of it's power.

The Airforce Texan, it's a big bore air rifle. There's this version IV88 has in the video which is the full sized barrel version. He has a suppressor on it too which you can add on later or get in bundled kit.

I'm not sure how powerful this is, I've heard people say different things, but all I know is it's got a power output that's comparable to Centerfire rounds. I think one dude compared it to a 45 colt. So you're not going to be getting full on Centerfire Rifle ballistic performance, but still pretty insane and impressive none the less for a non-powder based gun.

The full sized 50. cal one is cool and all, but the one I really like is the shorter 45. Carbine version.

Why is this cool?:
1: Because it's not legally classified as a firearm, you can get a suppressor for it with absolutely no paperwork or hassle involved, and hunt with it suppressed.
2: You can get it shipped straight to your door (in majority of places, some few exceptions)
3: Ammo is pretty cheap, and you can cast your own pellets/balls yourself.
4: If you live in a country where getting a gun for hunting is super hard. Though some places do have Power output limitations, namely the U.K. but even then the U.K markets still do sell a version of this.
5: Gives Convicted Felons an option to Hunt with. I know a couple of Felon Youtubers who can't hunt with Firearms, but have done videos with one of these.
6: It's a pre-charged pneumatic so you don't have to carry around a bulky tank with you 24/7 when it's filled.

Some downsides I can think of are: It's a single shot, so defensive options for felons (for the shortened carbine version, you can totally forget that bigass rifle one) are going to be spotty at best, but not totally impossible,
I think it can only hold 3-4 shots before the tank needs to be refilled btw.
Another downside is the Cost of Buying tanks and refilling the air.

I've been pretty interested in this thing for a while as a suppressed hunting option.

polymer ammunition... can be used in rifles with fluted chambers, like a CETME.

some years ago i acquired a few thousands rounds of "Polymer Cased Ammunition" from PCP Tactical in a few calibers, including 7.62 NATO, and it functioned fine in my G3A3, but often had cracked or split necks. the 5.56 NATO did not have this issue in my HK33KA3. i think it depends on caliber and pressure. typical CETME flutes are 0.035" deep, and G3 (and other derived) flutes are 0.0215" - 0.0280" depending on manufacturing year and caliber. i think one of the reasons that it works well enough in the HK firearms is that the flutes are produced by mandrel rather than EDM or machining, so they have a more rounded profile than you would think. on the flip side, a friend's 9mm MAC-11 did not like the 9x19mm polymer ammunition, but perhaps this was due to the 115gr projectile and mediocre velocity (around 1100 i think, target ammo speeds).

i'm sure there's teething issues with any new ammunition produced commercially when it hits the market.

i still find it a bit funny that people went off the deep end on forums for polymer cased ammo when it first was available, despite using plastic hulled shotshells for decades, although i do get the more reasonable argument about temperature and pressure...

Enough already, I'm buying it, I'm buying it... those viral marketing campaigns are getting pretty elaborate.

Based S&W.

Ok Smith, that SD40VE is getting bought new damn it, sthap, my dick can only get so erect. It'll be fun mounting a laser and 25 round mag on that 40 cal SOB too, make all the twatter brains cry that you allow such basedness.

 

[Club Sandwich]

SD40VE

it's worth mentioning that SD40F magazine bodies are interchangeable with the SD40VE although the baseplate may require a knife to shorten it slightly to fit. the 9mm magazines have the same follower/baseplate/spring/retaining plate as the .40, and the the 9mm magazine body is extremely close, it's possible to bend the feed lips to fit .40 S&W although i strongly don't recommend doing this unless you get the mags for free or something and are okay with them being "range mags". you can sort of use them as-is without bending but you may get failure to feed sometimes. speaking of, the magazine and barrel are the only different parts between the SD40VE and the SD9VE, so a conversion kit is basically a magazine and barrel.

the SW (Sigma) parts are also mostly compatible with the exception of the slide itself, but may require slight fitting. certain Glock parts are also compatible with minor fitting like the slide lock and a firing pin spring.

That's VERY nice to know, I can get 16 rounds of 9mm on tap just with a barrel swap. Same with the glock parts. I know I can swap sights with M&P ones, so tritium sights will be in its future

Also just looked up the SD40VE at my LGS. $375 with 2 14 rounders. I want it new, give some money to smith for being good boys, that's a steal when the mags should make it way more.

 

[Club Sandwich]

that's a steal when the mags should make it way more

original mags are $20 (thereabouts) on gunbroker and it's easy to win those auctions or buy it now.

original part numbers if you want to google NOS:
S&W Sigma / SW40 14-round: 193550000
S&W Sigma / SW40 10-round: 191790000
S&W SD40 / SD40VE 14-round: 199270000
S&W SD40 / SD40VE 10-round: 199280000

as i noted, all of the above magazines are compatible with the SD40VE, but for the older Sigma/SW40 magazines, you will likely need to trim some plastic on the baseplate (the magazine body, follower, spring, et c are the same as the SD40/SD40VE).

Well that's something to think on. I could get the 10 round model cheaper, upgrade later to 14 rounders. Also thanks for the Sigma info. I love that it was the gun that made Glock chimp out.

 

[AGPinochet]

My biggest question is if it can be used in rifles with fluted chambers

TV Says at least right now, No.
But my mind is simply afire with curiosity regarding this mysterious LWMMG. That text blurb is literally the only reference to it I can find anywhere.

PCP Tactical

PCP is a very interesting yet very low profile company. I used to incorrectly think that it was a sub-brand of Gorilla Ammunition (in fact it is the exact opposite) and they have been working on Poly-case ammo for sometime now. Recently culminating in a military contract (although the actual logistics of this baffles me because DOD is going whole hog on the Sig 6.8 so I don't get the point of buying Poly cased 7.62.). Somehow their polymer cased, steel headed ammunition is technologically distinct from True Velocity's polymer cased, steel headed ammunition to have avoided any legal drama and vice versa.

 

[Seafarer]

Here is an interesting gun I’ve come across:


The TOZ-81 MARS, a 5-shot revolver intended for Soviet Cosmonauts.

It is chambered for .410 shot shells but could also be chambered for 5.45x39 with a simple barrel swap. It also came with a detachable stock that had an emergency radio transmitter with a retractable antenna built into it, which would send a distress signal when activated.

The First update of 2023 for the Sage Dynamics White Paper on Handgun MRDS's has been released

https://www.sagedynamics.org/_files/ugd/7dc128_6377087e72264cd18dbcb04eea4686ce.pdf

Also, Aaron Cowan got invited out to Trijicon's HQ recently and was apparently shown something he is super excited for. I would think it would be an Enclosed MRDS, but Trijicon just refuses to make one of those so probably a gen 3 MRO.

Steyr has announced a rifle that has the option of being chambered in .277 Fury, to my knowledge this is the first announced Non-Sig firearm with the option to be chambered in the round

I looked up the bizarre potato looking thing on the end, and the idea intrigues me. Anyone in the thread have experience with flow through suppressors?

They sound like an idea I had for a similar device with a purpose I won't disclose (it wasn't sound suppression, much simpler, and the end result would have been much bigger, but to be clear, I wasn't intending it at a way around the NFA either) and in thinking up the idea I realized it might result in sound suppression as a side-effect but never really did anything other than think about the design...so I'm curious how effective these things actually are.

That was what first piqued my interest, probably because it was so unusual. AFAIK they're supposed to produce less fouling & backpressure, at least, and don't heat up as much (for higher round counts). I've found very little actual information on the can itself, either of it's design or testing results.

I poked around a little too, and of course found the autisms at Snipers Hide debating about it: the consensus for whatever it was worth was that it's useless for bolt-guns (which makes sense based on what you found) but for semi-autos or autos they can be a decent sound reducer, though everyone seemed to agree that on average they are not as quiet though testing as of 2020 hadn't really been done, I dunno if that checks out today though.

The company that's making 'em still seems to be in business so they must be good for something I guess. Or they got a juicy contract from daddy warbucks and haven't run out of cash or inventory yet.

My original thought was that it's essentially a flash-suppressor taken to the nth degree. And it was interesting that General Dynamics designed their own can, rather than use off-the-shelf suppressors from civilian manufacturers; although it also speaks to how big their original base of funding was, besides federal grants.

Ukrainian "Black Storm" bullpup chassis for the AK-47 & 74.

BS-3


BS-4

From The Armorer's Bench article:

The company says that both the BS-3 and BS4 are made from 1mm stamped steel and polymer. Black Storm list the weight of an AK-74 with the BS-3 kit installed, but without a magazine, as 3.4kgs. The weight of the BS-3 kit’s components is 1.2kg. A 2018 video, however, suggests that the kit’s components weigh just over 1.6kg (not including the rifle’s receiver, barrel and bolt assembly).

Black Storm list the weight of an AK-74 with the BS-4 kit installed, but without a magazine, as 3.9kgs. The weight of the BS-4 kit’s components is 1.7kg. Once installed with either kit the rifle has an overall length of 70cm (27.5in) down from 94cm (37in) for a standard configuration AK-74.

Black Storm list the BS-3 at 14,250 UAH ($387) and the BS-4 at 21,500 UAH ($585). From the information available it appears that the kits are purchased by servicemen privately, to adapt their issued service rifles.

A BS-5 has been developed, it’s unclear if this is in production but it is listed on Black Storm’s site and is said to be available. It has a length of rail along its top cover removing the need for an optic riser and also allowing the use of back up iron sights. It’s price is listed at 28,500 UAH ($775).

Feels like a horrible bastard child of the SA80 + ADS. At least it's not the triple barreled TKB-059 or double barreled AO-63 (I wish we could reverse engineer one in the US but noooo semi-auto laws would make it pointless).

Why is this cool?:

Just you wait the ATF will get their grubby hands on it and ban it even if it's legal.
