Aero Precision M5E1 FDE 308AR
There are a couple simple reasons to utilize a Nickel Boron 308 AR Bolt Carrier Group in your 308AR and AR-10 rifles. The Nickel Boron Coating by FailZero is super slippery this means the bolt carrier group can operate with much less lubricant, the bolt carrier group will be easier to clean and the coating should allow the bolt carrier group to outlast the weapon under normal operating conditions. Less wear will also occur in the upper receiver. The finish also looks pretty slick.
The Aero Precision upgraded .308/7.62 Nickel Boron 308AR Bolt Carrier Group BCG is an eye catching addition to your AR build. Mil- spec dimensions and coating ensure the highest quality and correct component interface. Visit Aero Precision

Drop-in bolt and carrier group has a self-lubricating surface that eliminates the need to apply oil or grease that can attract dirt, dust, unburned powder, and carbon and lead to cycling failures. Proprietary EXO-treated Nickel Boron finish produces an exceptionally hard surface that’s 40% more wear resistant than chrome plating, with an ultra-low friction coefficient. Surface is actually harder than the substrate underneath and will not peel, flake, gall, or rub off. EXO-treated Nickel Boron finish bolt/carrier groups have been tested to function reliably without additional lubrication up to 50,000 rounds. Reduced friction also means less heat generated by metal-on-metal contact, so the gun runs cooler and parts last longer. Easy to clean, too—fouling brushes right off. Before treatment, parts are shot peened for surface uniformity and magnetic particle inspected to make sure there are no hidden flaws. Gas key is hardened to USGI specs, chrome lined to resist erosion, and comes already staked to the carrier.

Machined from 7075 T6 aluminum, the CMT 308 AR STRIPPED BILLET UPPER LOWER RECEIVER SET is ideal for starting an AR-style .308 rifle build. Receiver set uses standard DPMS type .308 lower parts, bolt carrier group, charging handle, and dust cover. Upper receiver is compatible with DPMS high profile style .308 handguards. Bolt catch assembly uses a hex head screw instead of a roll pin for easier installation. Upper tension screw is built into the lower so tightening the upper to lower is quick and easy. Ultra flared magwell on lower is wire EDM cut to accept P-Mags. Receiver set includes take down pin detent spring retention screw and a Mil-Spec hardcoat anodized finish.

Genesis CNC is proud to offer our Gen-2 80% .308 Lower Receiver and .308 Stripped Upper Receiver which now provides the market with increased compatibility and options across the board.
The Genesis CNC .308 Upper and Lower Receiver pair is not only the foundation and starting point for the Rifle Builder, but also our parts allow current owners of LMT® / KAC™ / La Rue™ / Les Baer™/ Armalite™ .308 rifles to add another compatible Upper Receiver and build on their platform. Generally speaking, this has not been a readily available option.
We have re-designed our Jig Assembly with dowel pins and a single base which is a far superior design to our previous model.
In the future we will be offering our jig with and without drill bushings with a cost reduction for jig assemblies without the drill bushings for the single user.
The Gen-2 80% Lower Receiver is not only compatible with LMT and KAC .308 Rifles, but also creates the option for current owners of Armalite™ .308 rifles to convert their rifles to accept PMAGs® and other SR series magazines.
Designed to accept a DPMS™ Lower Parts Kits, with the exception of the 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.
With our Gen-2 .308 Upper Receiver, 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 the shooter wishes to re-configure for competitive shooting, Hunting, or set up a Long Range Precision Rifle…without having to purchase a complete new rifle. The Genesis option provides a significant cost savings option for the individual.
