I'm getting ready to build a new pistol upper (eventual SBR), and am trying to weigh the value of a 7.5 inch bbl with a noveski pig (kx3) vs. going with a 10 inch bbl with a mini-compensator. I figure both options wind up to be about the same overall length, but wanted to see if there are any other key factors which put one over the other (velocity loss is one obvious consideration).


Any thoughts?
