I just received it in the mail and have put less than 100rds through it. I am getting rid of it because I have an M4A3 upper on the way and I dont need 2 M4's. I paid $499 plus shipping for it, it includes the bolt, carrier and charging handle.
I am looking for other uppers, lowers(local, dont want to deal with transfers), ACOG, Aimpoint, BUIS, Beta Mags, or?...
bottom one, UPPER ONLY.here is the link to the post from CMMG
