The Small Arms Thread, Part 8: 2018; ICSR to be replaced by US Army with interim 15mm Revolver Cannon.


Recommended Posts

So I completed my ultralight AR15 build. I could shave off a half pound but it would cost me quite a bit (titanium BCG, buffer, receiver extension, misc other small things).

 

Parts:

Rock River lower with their two-stage trigger

A2 grip (was the lightest option I had, it formerly had a magpul)

MFT minimalist stock

Random endplate with sling loop

Standard Colt M16 BCG

AERO precision upper without forward assist

14.7" pencil barrel with pinned gemtech suppressor adapter

Aero precision lightweight mlok handguard

Holosun optic

 

Shot it this weekend with no problems at all. Gun works and shoots great, and my goal was to have a rifle under 6 pounds I could actually use for stuff.

Bone stock 6920 for comparison (with issue nylon silent sling)

Let's all take a trip back to the late 1970s and early 1980s.  This was the time of punk.  This was the time of despair.   Punk was all about minimalism; strip everything down to a few chords, wear

Stechkin's Abakan (TKB-0146). https://www.kalashnikov.ru/abakan-stechkina-avtomat-stechkina-tkb-0146/        Bullpup, system of "recoil impulse shifted in time", 2-stage

So what, my 5.56 rounds are groundbreaking too if I shoot the dirt.

I have seen only a pushback, that was only directed to the idea "many .50 bad", many didn't have a problem there with the focus on speed, altitude, evasion.

But making a B-29 from a B-17 is like removing the 37mm gun turret from a M3 Lee and name it M4, needs more than that and most important time.

 

How much would an B-17 win in altitude, speed without the defensive armament?

(I stop here, very off-topic.)

 

The point is that the B-17 needed to be replaced with something higher performance, but casualties still would have been less with faster, higher-flying B-17 variants.

   Mexican police killed 4 militants of the CJNG cartel in the south of Veracruz. The police noticed a gangster moving around the city in a military plate carrier. He was under surveillance and he brought the police to the shelter of the cartel. A large number of weapons, helmets and other equipment were found.

The Modification of MAS-36 rifles in #Idlib is fascinating. 

This modernised gun has a replacement MG barrel (Likely 7.62x51), new aluminium furniture & stock, AR-15 grip, as well as what may be 3D printed parts. These rifles are reportedly very accurate- this is suppressed too.

Yet another victim of the merciless modification of the huge amount of unneeded French MAS-36 rifles in Syria.
Now a WW2-era bolt-action rifle has become a pistol. Moreover, it seems that it uses 7,62x51 ammo, but not the original 7.5x54 due to its rarity.

   Lazarev's video on MP9. Not much, some video of shooting. 800-1000 RPM, used by French president security service, pretty good standart kit (aimpoint and suppressor). Very big amount of smoke in shooter face is spewed by gun during firing with suppressor, especially in full auto. Suppressor is mounted on special device, which is not directly connected to a barrel. Have some problems with durability of charging handle. During studio recording weapon is airsoft version, real one is only in parts of video on shooting range.

So as featured above you can see I got a wild hair and decided to build a light (sub 6 pound) AR variant. It worked. Weighed it today again:

So then I remembered my old (1980s) Colt AR15a2 carbine w/ 2 position stock and all that.

I weighed it with sling attached:

CAR15 wins by a fucking lot. FML.

Remind me to show you a picture of my lightweight build.

Well, it is not MP, so they probably have something in their MRAPs.

      There are many who feel that the 5.56 NATO is a superlative rifle round. Much has been said about larger alternatives to 5.56, such as various 6.5mm and 6.8mm rounds among others. Less has been said about smaller rounds. Off the top of my head, I can recall that there was a German 4.6x36mm round, used in the HK36, and the British 4.85x49mm round. Neither of these rounds managed to gain widespread acceptance. My knowledge of the voodoo that is ballistics is somewhat limited, so I'm uncertain as to whether these failures were caused by flaws with the rounds themselves, or because they were below some lower limit of effective bullet size, beyond which performance decreases rapidly. Could we see a resurgence of these concepts in the future, or do they represent an evolutionary dead-end?
