Aero Precision Nickel Boron 308 AR Bolt Carrier Group

Aero Precision Nickel Boron 308 AR Bolt Carrier Group

308AR Nickel Boron Drop-in bolt 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.

AR15 PMAG Vs 308 AR LR20 PMAG

AR15 PMAG Vs 308 AR LR20 PMAG – PMAG

One of the subjects that often confuses shooters about the AR15 and 308AR is the size differences in the platform. We often hear “Can I shoot .308 in my AR15?” and the answer of course is no. I think one of the easiest way to illustrate the reason why is with AR15 PMAG Vs 308 AR LR20 PMAG size comparison. In the picture above it’s easy to see that the larger .308 Winchester cartridge requires a larger receiver, chamber and of course a larger magazine. A 308AR magazine cannot fit into the magazine will of an AR15.
