.50 caliber pistol and rifle bore measurement >>> a Cali legal .50 BMG alternative!

[bwiese]

Thanks for the clarification, Jack!

Impactco,

Why not something on a 1911 frame? It has been done before. We might even be able to find the prototype if it still exisits. Or we could design a completely new semi auto handgun. I'd like one with a magwell in the PG. Now to design a a mag and feeding system that would allow the ammo to be loaded parallel to the PG. A to shot mag would not protrude much and give the shooter the ability to triple tap a threat.

Maybe we should all get together at some bar in Vegas on Jan 20 and toss some ideas back and forth.

yes, it already has happened to the .308 pistols. That is why .308AP ammo is not available to the public. .308 pistols were available long before people started making .308 AR pistols.

If .50BMG ammo was declared to be pistol ammo, then it would ban all steel core .50BMG ammo (basically all surplus ammo) and all the monolithic solids.

OK, thanks for that clarification. That would be a terrible result for everyone in the BMG community since they rely upon a consistent supply of milsurp projectiles. Our rental business relies 100% on .50 cal monolithic solids being available as well.

I'm liking the idea of a tripod mounted non-rifle/non-pistol in either semi-auto or bolt configuration.

So let me understand - I could order a .50 BMG AR compatible bolt upper. It would be tripod mounted with no shoulder stock and spade grips like this:

I could get Rich at Beltfedshooters.com to design a mount for the gun to either function on a military tripod like the M2 or on a bench mounted device. See here for a listing of his stuff:

I don't know if any of this is really practical. Just tossing out ideas. Recoil is going to be an issue even with a really effective brake like one from the AR-50 or Ferret.

Two questions:

Could it have a pistol grip or no?

Would this upper need to be on a rifle or pistol lower?

Bump for clarification on my last two questions.

[CHS]

Could it have a pistol grip or no?

Since it wouldn't be a rifle, the pistol grip would not be a prohibiting feature. Yes, it could have a pistol grip. To be cautious though, you may want to cut it down so that it only holds in the selector detent and is not actually a pistol grip. But legally, yes it could have one.

Would this upper need to be on a rifle or pistol lower?

You would want to build this gun up from a stripped lower. You don't want it to ever have been a rifle, or the resulting gun may be classified as a rifle. Just start with a virgin stripped lower DROS'ed as a long gun, and you would be fine.

Excellent, thanks!

A lot of people will be very pissed off if a couple people start making .50 pistols and get the surplus ammo banned. It should be viewed in the same way as the 5.45 pistols -> don't do it and/or don't advertise it

Yep, I am not building any.
I could make some money from those builds, but at what cost to the people who are more or less my brothers in arms?

The people who would build these are the same type as the people who do not want the May 86 machine gun ban abolished, right?
They have big money tied up in pre 86 guns and would lose a lot of money if the 86 ban went away.

I don't think your right about the type of people who are building 5.45 handguns. Most of the one's I know just like building different AK variants and have zero intention of selling them. As far as people who have .50 cal handguns which use a .510 projectile (mainly 50BMG chambered handguns), The one's I know of are just big into .50s and wanted a challenge.

I don't think the ATF&E will change the classification of any .510 bullets or 5.45 ammo based on a few home builds. As long as it's not done commercially, we should be fine.

I wasn't talking about the people who build 5.45 handguns.
I was talking about someone who would produce the 50 BMG pistols in large numbers, well large enough to kill certain ammo.

There we go. Thanks John and Bill!

So....pending written ATF agreement, a .50 BMG pistol would be legal in California since it is not a DD in Cali or at the Federal level. Plus it would not be a ".50 BMG rifle", so it would not violate the Cali BMG rifle ban.

Yes, I'm aware of the armor piercing ammo issue, but this has not happened with the few .308 AR pistols that are in existence. Obviously, if some manufacturer were to make a boat load of BMG pistols, it might cause a stir. Obviously, there is no big market for something like this.

I'm not saying that I'm going to do it, just final clarification that it is legal to do one....today.

This would need a forward grip to be manageable, hence an AOW transferred to a trust or corporation. It would also need a bullet button....Hmmmm



I love this:



It needs a bigger, more effective brake.



Let the firestorm of comments begin...now.

That's a great video. I thought that the guy firing the pistol was going to fall over. Recoil much?

I'm not sure why the fire suits were necessary other than for dramatic effect. When firing full power movie industry blanks from a short barreled DTC gun with a brake, there is a much larger fireball (about 4' across). They leave scorch marks on the concrete benches and set off every car alarm in the parking lot.

Thanks for everyone's input in this thread and beating back the FUD!

that is because the original video was cut down and you are missing the story,

here is the original.

Thanks for that!

oh, and Birdman originally registered his ".50BMG Pistol" as an SBR, so as to not trigger a .50BMG "AP" ban.
