Aero Precision 308AR OEM Rifle Brownells Exclusive

Aero Precision 308AR OEM Rifle

Aero Precision OEM 308AR

Aero Precision 308AR OEM Rifle – As I have previously mentioned on our AR-15 site I really like the concept of these Aero Precision OEM rifles. They consist of completely assembled rifles without sights, buttstock, and handguard at cost savings greater than the sum of the omitted parts. Basically we are not forced to buy parts we never use. Well, today I decided it was time to see what was going on at our best supporter Brownells and low and behold they have a ” Brownells Exclusive” Aero Precision 308 AR OEM rifle. Priced right about the price of the no-frills least expensive 308AR rifles from other manufacturers. In my opinion, the Aero Precision 308AR OEM Rifle is a better quality value.

The Aero Precision 308AR OEM Rifle is not available directly from Aero Precision and is currently available as a preorder from Brownells. Any visitors purchasing one of these please join the 308AR forum and share your build results and pictures with the group.

Aero Precisions October limited run builder set is for the AR15 platform and NOT 308AR/AR-10 (At times the M5 308 AR versions are available). Too interesting not to share here though. BlownDeadline is certainly taking Cerakote to a new level these days and the “Battleworn Orange Grey” finish is a testament to that. This picture above reflects a 15″ KeyMod handguard, M-Lok is also available. Visit Aero Precision for ordering information.

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.
