If you need a new upper receiver for your AR-15, consider the LANTAC UAR upper advanced receiver. This upper receiver is specifically designed to meet the needs of avid AR-15 users. Machined from billet 7075-T6 aluminum, this upper is sturdy and durable. The aluminum surface is treated with hardcoat Mil-Spec Type III anodizing to ensure a corrosion-resistant surface. M4 feed ramps ensure smooth operation of the firearm.
The bore of the LANTAC upper features a specially burnished surface that gives its interior a roughness average in micro inches of 16 instead of the common 32 to 63 or more. The extremely smooth bore internal surface greatly reduces bolt carrier friction, leading to a more fluid operation than would be otherwise. The SMOOTHCAM system featured in this LANTAC upper receiver includes a domed head CP-R30 cam pin to ensure smooth, seamless operation.
The CP-R30 cam pin used in this upper receiver contains no moving parts. The elimination of moving parts removes the risk of part to break or lock up. The circular head of the cam pins features a flat face to permit them to be used in any bolt carrier without the need to remove the gas key. Other machining details help reduce internal wear and tear to the cam channel.
The receiver of your firearm is responsible for containing most of the moving parts that enable your AR to load, fire, reload and fire again. Don’t skimp when it comes to one of the most important parts of your AR-15. The LANTAC UAR is an ideal choice for your black rifle.
