JL Billet AR15 upper receiver is machined out of solid block of 7075-T6 US aerospace grade aluminum on 5 axis machining centers and held to the tightest tolerances and Mil-Spec standards. These billet uppers are design to match our billet lowers to ensure a superior matched set for your next build. These can be purchased in raw aluminum or Type III hard black anodize.

This is a slick side billet upper and is NOT mil-spec meaning many handguards will not fit this upper without extensive modifications due to the flared body behind the barrel nut threads. It fits the JL Billet lower but fairly sure these are extruded and then milled instead of being forged. This won't hurt the average user but it is not as strong as a forged billet receiver (yes such a thing exists). JL Billet appears to want you to buy only their lower and hand guard for the best fit. I ordered mine raw and it appears to be bead blasted but the JL Billet lowers I received are not. I wish there was more consistency in the finish from JL Billet, my lowers needed a lot of work to be usable as they appeared to be rushed during production. These fit very loose on my JL Billet lowers.
