Pretty basic build, built it for coyote hunting got less than 50rds. 16inch criterion core with surefire closed tine muzzle. Aero bcg with aero m4e1 upper and lower. The lower has a small drill hole for front take down pin had a small blemish not allowing the spring to come back out. Other than that pretty basic has a geissele trigger in it believe its a ssa. B5 and BCM furniture.
