LANTAC UAR Upper Advanced AR-15 Receiver
The LANTAC SMOOTHCAM system is optimized for use with a Lantac NiB Nickel Boron BCG due to the domed Campin head for smooth operation. The Receiver features a blended cam recess for that BCG. Upper comes completely machined from Billet 7075 T6 Certified Mil-Spec Aluminum in Milspec. It has been Type III Class II Deep Black Hardcoat Anodized. Everything about the internals is machined for precision from the special burnished bore that gives a compacted internal surface with a roughness of micro inches of 16 as opposed to standard uppers with 32-63 so guaranteed smooth!
