Like new Aero AR (was a factory built pistol). Added the Lantac barrel and BCG. Added the quad rail. 3 position forced reset trigger installed. Runs perfectly. Add 150 for the Holosun ARO. Add 200 for the LS117 IR (IR only) laser. Will come with a matching magpul stock detached for you to do whatever you wish with. This was SBR'd but has been removed from the NFA registry. Open to trades for MP5 clones or other interesting trades.
