I have a lightly used b&t apc 9 pro with the standard end cap you can attach a brace to as well as the colapsing stock. It also has a reptilia grip, spare mag, sling, b&t magwell, Aimpoint t2 on a qd mount, and b&t vertical grip. All original parts/ manuals are included with original box. I planned on turning this into an sbr and never got the time. You would have to sbr it in order to use the grip and collapsing stock. I will piece out but would rather sell everything for 3400 that’s a huge discount from buying it all new, or 2700 with out optic. Call or text me at 281-802-711two with any questions/offers. Not really interested in trades unless it’s in my favor or a volquartsen mini mamba. Check out my other listings.
