Hi, I had owned 2 bshmasters that I had bougt 10 years ago or so, One an A3 CPM with the heavy barrel and target trigger and the other a stanard A-2 with iron sights. I still have the CPM but it is heavy, whic is ok for the club shoots. I want to get eiter an A2 upper 16" with M4 barrel profile or standard weight 20" A2. I live in NYS which means NO byonet lug no flash hider (no collapsible stock either but this is just about an upper). Muzze Breaks are OK and I definetly want one on this. What are the quality MFGS nowdays that make these...I loved bushmaster they were the primary mfg's of military grade (harduse) rifles, now I hear that is no longer the case.. any suggestions on MFG's. I want to get another hard use military grade upper in 5.56 Thank You Wanna kill these ads? We can help!
