I have a new in box, never assembled AR-15 lower receiver made by Doublestar Corporation. I purchased 4 in April of last year. I built a 16" KISS rifle and sold it, a 7.5" AR pistol and sold that and kept my 20" NM AR. I also have a new Rock River Arms Lower Parts kit. I will sell separately or together. Doublestar lower, Cal 5.56mm $120 RRA LPK $75 Both for $190 FTF. I would also prefer to sell to CHL holder (I'll show you mine if you show me yours - no bill of sale needed) Only trades I'm considering are air rifles in .22 - RWS, Gamo, Air Arms or similar.
