Build that custom AR10 you've always wanted with our matching AR10 Uppers from McKay Enterprises machined from 7075 billet with a blackType 3 Hardcoat Anodize .002" finish. Machined to Mil-Spec dimensions, caliber 7.62 X 51 MM (.308). These uppers will take standard DPMS style barrel, barrel nut and bolt carrier assembly.
The McKay Enterprises upper receivers are machined to the same precision as our highly praised AR15-A2 receivers as covered by numerous reviewers: (http://www.majorpandemic.com/2012/04/mckay-ar15-lower-receiver-review.html)."Just recieved 6 AR lowers that a friend ordered and had shipped to me. As a full time machinist I have to say they are PERFECT! VERY impressed!!" - Vance.
