I bet that would be fun in a SBR.

Yes, the AR is a great platform for the GI, as can be seen in the video the recoil is stright back and very little muzzle rise. With the 1-4 power scope on it I never have problem watching the target during recoil. It seems now when going to the range I shoot the GI more then any of my AR’s.

I believe I’ve read in one of the glossies that the law says you can’t have anything bigger than .520″, which means you can have things like a .512″ diameter bullet in your .50 Alaskan or something and still be legal. .512″ is actually about 13mm, so maybe the law actually says “Nothing bigger than 13mm…” or something.

What’s wrong with the .50GI as a pistol caliber? Assuming the .45ACP is a good self-defense caliber a bigger bullet should be even more effective, right? And as long as it fits in a single stack pistol magazine I don’t see why not.

Is larger than 50 caliber weapons legal in the US? I think there is some upper limit for rifles at .50 (BMG). Does this apply to handguns?

Finally, a practical use for the .50 GI. I would buy one. This would make an excellent SBR PDW.

9mm then .40 then .45 and now .50 – with that train of reasoning, I fully expect to buy a .75 AR-15 upper by next April.

If I had a dollar for the number of times I’ve wished I could fire a .50 pistol cartridge from an AR-15, I’d have .37 cents.
