I built my first, and so far only, AR with a 20" bbl and rifle gas. The lower has a spikes T2 buffer in it, which is 4.1 oz I think.
I'm building another upper - this upper is 16" with mid length gas. There is no muzzle device on it or planned. Am I going to get away with my T2 buffer using this upper? |
