Good morning all,
I would like to build/buy a 9mm SBR similar to the the Sig Rattler SBR, is this possible? if so will you please provide me where to look for an upper. I am new to this build idea however, I have believe I would need a piston upper, is this correct? if so does it exist? where?
Thank you for you time and input.
