I have a 9mm AR PDW that runs like a charm (6.5" barrel, runs on blowback).
It has a mil spec carbine buffer tube. I am considering putting the BAD Sabertube on it to cut weight in the rear. I realize the Sabertube is a "mid" length buffer system. Will I need to put a spacer in the tube for my carbine buffer to run or will I need to move to an A5 buffer for this mid length Sabertube? Thanks for your time, |
