In designing the Genesis 308 Upper Receiver, great care has been taken to ensure a high degree of precision. With special attention taken in the barrel extension area. The precision machining in the face of the barrel extension seat and bore diameter will allow you to build a more precise rifle.

With our Gen-2 308 Upper Receiver, the current owners of  high-end rifles such as LMT® / KAC™ / La Rue™ / Les Baer™ and Armalite™ now have the option to change the configuration of their rifle to meet their needs. Whether you wish to set it up for competitive shooting, Hunting, or set up a Long Range Precision Rifle without having to purchase a complete new rifle.

With our new Gen-2 80% 308 Lower Receivers the rifle-building enthusiast is now able to build up from scratch a second Lower which is compatible with the above mentioned manufacturers, many of whom do not offer their Lowers by themselves.
In this respect, our Gen-2 80% Lower Receiver offer the customer another option, which until now, has not been readily available in the market.

The Gen-2 80% Lower Receiver creates the option for current owners of Armalite™ 308 rifles to convert their rifles to accept PMAGs® and other SR series magazines. Our Gen-1 80% Lower Receiver required an Armalite® Lower Parts Kit, Armalite™ AR-10A® Bolt Stop, and AR-10A® Magazine Catch. In contrast, we have designed our Gen-2 80% 308 Lower Receiver to accept a DPMS™ Lower Parts Kits, with the exception of the rear take-down pin. Genesis will NOT include Rear Take-Down Pin.

Generally, this design change not only creates significant cost savings for the customer but also the DPMS™ Lower Parts Kits are more readily available for purchase.
