Bushmaster/Prof Ord SBR/Pistol Upper It has a 9 inch Barrel and comes with the QD adaptor so you can use a std AR flash hider. Includes B/C/CH. Fits nice on my Bushy lower. I have not fired it. I bought it from another member here last week and now I have a family problem and I need some quick cash. I paid $400 for it last week. I will sell it for $350 shipped.
