Cobratac Billet Match Upper Receiver
Cobratac's Billet upper receivers combine strength and perfection into a rock solid platform and cleaner lines to build your dream AR. It is compatible with all mil-spec bolt carrier groups and charging handles, and will work with most hand guards on the market. It is machined out of 7075-T6 billet aluminum and anodized with a durable Type III hardcoat. M4 feed ramps are cut before the anodizing process to avoid reliability issues down the road. Cobratac Billet upper Receiver yields a 65% increase in strength & rigidity over 6061 aluminum receivers. Additionally, the bore of the receiver has been honed and refined for a silky-smooth action you can feel every time you cycle it.
The Cobratac Billet Receiver is machined on a 6 Axis machining Center to reduce the number of operations/setups required to complete. This machining process allows the highest possible accuracy to be obtained over the traditional 3 or 4 Axis machining method. Barrel nut threads, as well as bore and barrel extension surfaces are all machined in one operation so that they are perfectly concentric and perpendicular to the barrel. This budget friendly Precision Upper is perfect for the long-range or competitive shooter. Compatible with most ambi-bolt catch levers.
