Did we have the capability to build a modern AR, magazines, ammo, etc, during WWII?

The AR-15 is an absurdly simple firearm compared to an M1 Garand or an FG42.  It would have been quite easy to produce.

Thompson sub gun required way more machine work. I think it could have easily been done. I mean most of us are building lowers in house with routers and a jig.

Well.

It would be wood grips, wood furniture.
Parkerized steel receivers. Chambered in 30-06. Weigh about 15 pounds. 15-20 round capacity. Box magazines doubling as a kudgle to bludgeon Japanese and Germans to death with.

Damn thing would be quite robust. No rapid fire. Hand guard would spontaneously combust. Maybe not. They'd probably use asbestos back then...

It would have failed miserably. But it could have been built.

remember all the sub standard powder that fucked with the early m16s in the 60s?  Where do you think the pencil pushers found it?

that and " aircraft aluminum" is a pretty wide term mettalurgically. IIRC we did not have the quality that we have now.

I don't know how much plastic was around in those days, but I'm sure that bakelite or something similar could be used for the furniture.

I'd imagine that it would have been chambered in something more intermediate back then, like .30 carbine or .351 Winchester.

easily, tolerances would be looser compared to stuff now, might be more finicky, oh and most likely have wood instead of plastic.

capable? you realize that the AR is a pretty simple, straightforward rifle right? both in terms of design and ease of manufacture.
Link Posted: 10/23/2018 11:10:05 PM EDT

Yeah, but it'd be about a pound heavier because of all the steel and wood we'd have slapped on it.

Bakelite is a trade name taken from its inventor, Leo Baekeland, who invented Bakelite in 1907.

Because resting on your laurels means you get surprised when, say, the StG-44 comes out, or the Soviets are fielding AK-47 and AKM and you're still using the best rifle available in 1936.

Yeah, the M1 was definitely The Rifle To Have when adopted, but by 1942 in the middle of a war...you might want to make sure you're still working on the next rifle. Because the other side is (or you damn well should assume will be) working on improvements, too.

And as much as I love my M1, the AR-type is definitely superior to it. Even an AR-type in Caliber .30 (i.e. 30-06) would be an improvement as a combat weapon.

Nope.

Even if it had been designed, it never would have been adopted and no major manufacturing firm would have been able to get a contract to sell it to the government.   And most likely wouldn't have been allowed to sell it to foreign governments.

People don't think the 1942 war economy be like it was, but it did.

Sure.

Could they be mass manufactured to equip an army?

Probably not.

Forged 7075 aluminum receivers isn't something our industry was really geared up to make in WWII. Likewise 7075 impact extrusions for the buffer tube.

Lots of advanced polymers and composites too.

30 Carbine was made from Day 1 with non-corrosive primers due to the M1 Carbine's gas system. No real reason why the '42-AR couldn't have the same treatment.

He makes a good point about the powder though. The cleaner powders enjoyed from the 50s/60s onward were often products of WWII chemistry research.

The first 7075 was developed in 1943 in Japan.

Even if the allies had access to the Japanese process, it was rather late in the war effort to invent the AR, tool up manufacturing for it (in a material that was brand new), and get it out to the front lines.

Nevermind having to develop a new cartridge, or the problems we faced during Vietnam associated with poorly selected powders being used to load 5.56.

The '42-AR would be constructed with a material not invented by mankind until 1943.

Agreed. Didn't help the post-war travails of the AR-10 and AR-15 (and the early members of the M16 family...) that Ordnance insisted on using "reclaimed" WW2-surplus powder, though, to include stuff remade from scavenged cannon powder, from some stuff I've read.

Okay, so? Receiver can be made of other materials than 7075-T6, albeit with a cost to weight or durability, depending on what you specifically select. But stainless for gas tubes existed (ref. the problems keeping the M1's gas cylinder darkened and non-shiny in the field) and the lack of 7075-series aluminum really isn't a big deal for the receivers.

Cost cutting measures fucking with not having a chrome lined barrel probably played as huge a role in fucked up M16 reliability as did powder selection.

The select fire Armalite AR15s fielded BEFORE Vietnam actually kicked off seemed to have worked well enough in the hands of SOG.

It took actually getting adopted and type classed the M16 to get properly ficked by Nader.

Replace some uniquely AR parts that are aluminum with steel and 1940s era weapons makers likely would have done just fine.

Look at the M3 Grease gun in terms of what kind of furniture an AR could wear.

Easily.

I think problems with materials and powders could have been pretty easily overcome. This was a time in which quite a few more ridiculous ideas were floated and then implemented.

You could probably cast the metal parts from the aluminum available if you didn't wanna make them from steel; and the powder issue could probably be overcome. I'd be surprised if you couldn't jury rig some sort of adjustable gas block to go with it as well.

I think the end result would probably still be a little lighter than the rifles of the time as it'd be shorter and more compact.

The underwood typewriter company designed the stamped type 4 trigger assembly for the M-1 carbine. Imagine what they and GM’s Guidelamp division, who designed the m3 grease gun and I believe the folding stock for the m1-a1, could have done with an AR-18.

Never would have been accepted thanks to the Cult of the .30/Cult of the Rifleman.

They still exist and still are trying to kill anything less powerful than .308.

M2 Carbine in 5.7 Johnson would have been tits, and the Garand in .276 (as originally intended) would have been better than .30-06.

DIGAS was already around, and France built the MAS49 just a few years after being conquered and blowed up twice.
