This billet upper AR15 receiver from LanTac is ready to build your ultimate modern sporting rifle. The UAR Upper Advanced Receiver is precision machined from 7075 T6 aluminum billet and features the SMOOTHCAM system. It has a special burnished bore for ultra smooth operation that reduces bolt carrier friction. Barrel extension, bore and barrel nut threads are all machined at the same time to ensure they are perfectly concentric and perpendicular to the barrel assembly. The cam pin recess channel is engineered to be exceptionally smooth, ready to accept the included CP-R360 domed head cam pin. This specially designed radial domed head cam pin moves thru the upper with a minimum of drag and wear. The UAR features M4 style feed ramps, a flat top picatinny rail, and a Mil Spec Type3 Class2 deep black hardcoat anodized finish. This LanTac Upper Advanced Receiver is exactly what you need for that next precision AR build!
