http://palmettostatearmory.com/inde...psa-16-hammer-forged-midlength-upperpper.html this is the set up i have. Ive shaved the FSB and installed a centurion arms 12 inch rail( id prefer to keep my rail and BCM BCG) What should i ask for just the upper no bcg. Im wanting to go LW 14.5 with permd fsc556 should i just take this barrel i have on here now and swap it? I have the tools and means to do so if needed. Wanna kill these ads? We can help!
