So I tried to search far and wide and couldn't get a definitive answer so I figured I'd throw it out there....

 

 

I planned a 22lr AR pistol build using a forged lower using a 7" taccom pistol upper. Since this is a 22, it's a blow back so no need for a buffer tube/spring/etc. No handguards allowed clearly which saves me some weight.

 

My calculations put this at weighing around 45 ounces with an empty mag in it. The barrel comes threaded so I was either going to have the threads removed or add on a compensator and tac it on (+1.5oz) so it looks like grand total it's going to come in around 47oz with an empty mag.

 

So everything looks OKAY so far.

 

What happens when I put on a heavy red dot and it goes above 50oz? Does that constitute manufactured weight? Or does it not count against the weight limit. 

 

 

Just for kicks it'll look something like:

But obviously muzzle device will be different.

The mag does not count in the weight. Neither would an optic.

Well if that's the case I've got plenty of buffer room... thanks.

Also - yo udo not have to pin the muzzle device on a pistol

You raise an interesting situation. Are you actually the manufacturer of the pistol if you build it? The general accepted answer is no. Then if no, why would the "substantially identical" clause apply to you?

It's a good question that I don't want to be the first to challenge , I rather it fit in with the ssubstantially identical clause. Doesn't really bug me too much as I can have a magwell grip if need be and everything else is to my liking.

Or you can get a carbon 15 which shoots .223 and weighs 47oz.

^ I just may know someone who has one in stock................................. 

Never understood the purpose of an ar pistol. Sbr yes, pistol no

Must have never shot one.

Purpose = fun at the range, with big fireballs. That's about it lol...

Actually..i havent. I seem to never shoot anything. I really need to change that this year

You're like me. I rarely go shoot yet I keep buying more guns and ammo.

AR is actually one of the few guns where SBR is not much different than pistol.... if it is an actual AR with a buffer and buffer tube.. the tube makes for a perfectly functioning stabilizing point against the shoulder.. not much different with the stock..

Quick someone should write the ATF a question about that.

maybe they will tell me I have to take the buffer tube off... lol
