Why you say 10.5" run the best?
5.56 or .300 blk? Does it matter?
I'm prolly gon get 1 of both, or 1 pistol (buffer tube) with 2 uppers (one 5.56, one .300blk).
I want 1 AR pistol & 1 AR rifle
What I said was my 10.5 runs the best out of the piston uppers I have. I'm talking in terms of maneuverability, reliability, and being suppressor friendly. I have had issues with gas blow back with my D.I. Ar's, when used in conjunction with suppressors. Piston driven uppers gas systems are adjustable, they can be set to the shooters liking.
I have a 16" and 8.5" 300 BLK, both are D.I., so I can't speak for the piston variants.
I have owned AR and AK pistols, they aren't practical in my experiences. They are meant to be shouldered, which doesn't lend well to pistols.....

technically you don't own any guns...so you bought all your weapons through private sales?
@ the sbr thing yeah I would admire the SBRs from afar if you are opposed to paperwork. Thing is (which you probably know) having an upper less than 16 inches in the house with a functioning rifle lower is a no-no. Yeah sure you're not gonna get popped unless they kick in your door for something else and find it but I don't need those type of problems or do I even like thinking about giving them bitches 10 years of my life on some dumb shit.
