Aero Precision Nickel Boron 308 AR Bolt Carrier Group

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

Nickel Boron coating by Fail Zero. Learn more about Fail Zero Nickel Boron Coating Services.

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.

338 Federal 308AR Stripped Lower Receiver

I just saw this at Brownells. A .338 Federal Marked Stripped Lower for $109. This can be used for a 308AR and is a great price.

 

338 Federal 308AR Stripped Lower Receiver – Rugged, fully machined 338 lower is ready to be the foundation of a hard-hitting long-range tactical, competition, or hunting rifle built to meet your exact specifications. Precision milled from a solid billet of high-grade 7029 T6 aluminum, with extra metal in the right places to handle thousands of rounds of full-power ammo without flexing or stress-cracking. Mil-spec hardcoat anodized for extra surface strength and corrosion resistance. Beveled mag well aids in fast reloads, and the integral, straight triggerguard milled from the billet with the rest of the receiver provides clearance for a gloved trigger finger while adding to the structural strength of the receiver.

Accepts standard 308-AR upper receivers & components.
