300 blk SBR upper - 05/04/16 05:02 PM
was going to build one to utilize my silencerco hybrid. however, i am seeing a good many uppers assembled for very reasonable prices. i am thinking 8-9" barrel with slim forearm coming flush to threads. any advice on what to stay away from or what you liked? not needing match grade stuff, as this gun is obviously not a 1000yd match rife.
