I am getting ready to Form 1 my first lower. What is a good caliber to get an upper in for an SBR? I have a 30 cal can so I will want to suppress it also.

I bounced back and forth between 9mm and 300BLK I'm going with the 300BLK in 8.5 to 10.5 length. Till the SBR paperwork comes back.

are you allowed to swap uppers on a sbrd lower?

with the assumption that barrel length/caliber is different than what the stamp has on it...

Probably not what your looking for but my dream SBR would be one of the glock mag lowers.

A 9mm glock mag fed SBR would make me so happy. I know you can't swap out uppers doing that but I still think it would be badass.

9 = .354
7.62 = .305

I would say no go for that one and be safe.

This is why I shouldn't post from work. Little sleep and no coffee makes me say backwards things. I knew it was one way or the other. Thanks for correcting me.

I have a 7.62x39 SBR. It started at 7.5" but I wasn't comfortable with the short barrel and my can so I changed it up to a 10.5" barrel. It does everything my 300 BLK SBR did since I never used subsonic ammo in my 300 BLK. What are your questions?

Is it worth it? is it reliable on the AR platform?
