LANTAC Upper Adv Receiver Milspec Type3 Class2 Deep Black

Safely build your firearm with this Lantac Advanced Receiver Multi-Caliber to ensure smooth operation with every shot. Lantac machined these Rifle Parts from a billet 7075-T6 aluminum billet and then hard anodized them for complete ruggedness without the heavy weight. The Lantac Smoothcam Receiver Multi-Caliber is a precision-machined upper that uses their patented SMOOTHCAMTM system to greatly reduce friction and create ultra smooth operation. This upper receiver has a burnished bore that eliminates the majority of overall roughness whereas standard bored or milled uppers have an average roughness of 32-63microns/cubic inches. When used in conjunction with the CP-R360TM low friction cam pin, you'll notice decreased wear on the bolt carrier due to reduced friction against its internal surface. Also, the barrel nut, bore, and barrel fixing assembly are all machined in one operation so that they are perfectly concentric and perpendicular to the barrel and fixing assembly. Install the Lantac ARCA Advance Receiver Multi-Caliber to upgrade your rifle build with one of the best in the business.
