MAXIM DEFENSE SWC BCG Listing ID: 2974132

I am selling a Maxim Defense complete bolt carrier group for a Maxim Defense AR15 SCW pistol. These bolt carriers will not work in a standard AR15. A friend sold his SCW pistol and gave me the extra bcg that came with pistol kit. This bcg is for 5.56/300 BO and was slightly used. I want to trade for a standard bcg for around the same value. I am located in Navasota Texas and can meet in College Station.
