OK, say I actually did it...

[BattleRifleG3]

At first I was all talk, cause of course talk comes before action, ideas before designs, designs before products...

But after doing a couple common rifle conversions/builds, and designing a couple accessories, and now doing dimensioned blueprints of a semi-auto rifle, I'm thinking some of them may actually take off.

While I'm sure people may be proud that a member of a forum did something like this if it happened, from all the poo-pooing done to interesting stuff out there, I'm wondering what would actually take off.

So here's a few of the more realistic freakish concepts, from simplest to most complicated.
Which ones would you go for?

Ok, so I'm an idiot and forgot to hit the Poll Button. So I guess we'll have to do it the old fashioned way where people actually talk about what they want. Here are a few ideas:

1. Grip/stock conversions. Stuff akin to BlackJack's CAR stock mount for AKs, but far simpler, such as AK grip mounts for the wide range of AR-grips, including SAMCO, ERGO, Duckbill, etc.

2. Daewoo or AR-180 type gas system conversions for AR-15s. Daewoo (fixed piston to carrier) would be most similar to AK, involve the most change to the original equipment, and hurt accuracy a little, but be the most reliable. The AR-180 type (separate two piece piston and carrier) would be more complicated in and of itself, and possibly be more expensive, but be more reliable than standard AR-15 and almost as accurate.

3. Stamped AK parts on a milled Aluminum receiver designed to accept magazines and other accessories that wouldn't fit standard AKs in 223 and 308.

4. Single Stack Romanian AKs in 35 Remington with a proprietary magazine. (involves a mere rebarreling, new mag, and feeding system)

5. Saiga shotgun based AKs in 444 Marlin or 44 Rem Mag. (feasibility all depends on how overbuilt the Saiga 410 is)

6. Standard shotguns like Mossberg Maverick converted to an upside down bullpup configuration placing the tube above the barrel. (involves Moving FCG to fire from beneath the inverted receiver)

7. Standard Pump Shotguns safely converted to 45/70, 44 Rem Mag, and 444 Marlin

8. Pump or lever action carbines in 7.62x39mm or 223 that feed from military mags and basically serve as low maintenance plinkers or for non-semi-auto hunting states like PA.

9. Semi-auto rifle offered in many calibers up to 300 Wby, 375 H&H, and 458 Win Mag. Of course it would be friggin huge and heavy. Smaller versions in 300, 338, and 7mm Mag would feed from 1918 BAR mags, as would versions in 30-06, 35 Whelen, 270 Win, 280 Rem, 25-06, etc. Short action versions like in 358 Win would use G3 or FAL mags. Intermediate caliber versions would probably be impractical to compete with ARs and AKs.

10. Larger caliber wildcats of intermediate and full power cartridges, including 35, 40, and 45 caliber. Includes intermediate 35 carbine round (based on 7.62x39mm or shortened 35 Rem,) 40-308 (or 408), and 45-284.

Big bore pumps and autos would of course be used most by guys who like big guns and they cannot lie, 44 Rem Mag perhaps also for ammo interchangeability with revolvers for both hunting and defense. Might also be good brush-buster hunters. They would probably be marketed mostly as dangerous game control guns for rangers/wardens or wilderness residents.

The whopper magnum autos would also mainly be bought by guys who "like big guns and they cannot lie", but would be marketed to dangerous game hunters, long range snipers, and special police or military forces.

The 30-06 versions would be for those who want a more reliable alternative to the Rem 7400, and less expensive than Benelli or Browning. Saiga 100s and VEPR Hunters may whoop its arse, but being domestically made absolves it from "sporting compliance" that the VEPRs and Saigas have to comply with. It's also not stretching an existing design for a bigger round, but designing a rifle from the start to use it and its big magazines.

Aluminum receivered AKs would allow use of AR furniture, a special scope mount dust cover (hopefully a good one), and AR-15 magazines in 223 AKs. 308 versions could use G3 or FAL mags. Aluminum allows a lighter but more rigid receiver, able to be better machined to be strong where necessary and not have unnecessary material. Also a little more bulky for attaching other items. Hopefully more accurate too. Using stamped parts including trunions would allow maximum parts interchangeability and keep the strongest parts of the original steel model.

Larger caliber wildcats would provide greater short range hunting power at the expense of flat trajectory, and provide big bore options on common semi-auto platforms.

1 and 3 would probably be the best sellers :assult:

Sometimes BR ya gotta think simple AND freakish - such as the twin AK tripod mounted, hand cranked bullet sprayer that I am working on. Freakish definantly works for this'n!

[whirlwind]

id like to see a 50BMG necked down to a 338 in a semi auto! that would be cool!:assult:

I saw one of those on gunbroker....but you say you are building your own?? I sure would like more info on that project!!

Ok, how about the ones I listed?

Forcing high pressure fluid flow from a large diameter channel (cartridge) into a smaller diameter one (bore) results in a phenomenon called throttling, that reduces the energy. The more you throttle, the more energy you lose in the form of pressure. You could build neck down a 50 BMG to 224 caliber, built a gun big enough to take it, build a barrel long enough to use up all the pressure, and still have limits because of the throttling effect. This is why there is no 224 Remington Ultra Magnum and why the 220 Swift is on the high end of 22 caliber rounds.

The smaller you neck it down, the more diminishing returns you get from throttling. I'm not sure, but this may relate to throat erosion.

That said, there was a 35 caliber wildcat on the 50 BMG. I forget whether it was called the Mach 3 or the Mach 5, obviously for its speed. Were it the Mach 3, that would be quite unimpressive. The 300 RUM propels a 180gr bullet at Mach 3. Some of the fastest small bore rounds hit Mach 4.

Seriously, guys, does anyone want any of the above?
