Building a 12 inch Grendel that is going to be suppressed
#3
I did the same as you while I was waiting for my TBAC Ultra 5 to clear NFA's terrible system.

I used the Maxim PDW brace with tiny buffer and their really stout, short spring, and it runs like a raped ape with 120-123gr Federal OTM and Hornady AG ammo.

I have a Group Buy barrel with a .068" port.

I shoot it now suppressed with the Bootleg ABC carrier turned all the way to suppressed setting, with my TBAC can.
