Knocked it out the park with this one!
Don knocked it out the park with this offering! Tighter bore for a tighter carrier lock up. Design features to reduce upper flex when firing. Goes great on forged or billet lowers. Tight bore fit around the barrel extension (mine required thermal fitting). Fit and finish is great. Perfect upper for precision accuracy guns.
