listen folks, i've been trying to build this AR for about 4 months. all i lack is a barrel and a bcg. the barrel is easy to acquire. the bcg on the other hand, is a different story. just about every retailer online is sold out with no eta of new deliveries on bcg's that are reasonably priced. sure i could get a nickel boron coated bcg right now, but i'm not paying $200+ for a damn bcg. if anyone has an extra bcg that they would like to sell at a REASONABLE price, plz contact me. i would just like to finally get my first AR rifle finished. thanx.
