Buy Failzero.Com Ar-15 Bolt/Carrier Group

The Failzero.Com Ar-15 Bolt/Carrier Group is only 9.99 at Brownells these days, which seems to be a pretty good price.

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 treatment 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 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. Complete Bolt/Carrier Group comes fully assembled and ready to drop into any mil-spec AR-15 upper receiver. Includes bolt, bolt carrier, hammer, firing pin, extractor, cam pin, and gas key. Every kit is test fired for proper function before leaving the factory. Separately available Carrier comes with gas key installed and staked. Bolt includes extractor, ejector, and gas rings installed. Add the firing pin of your choice. SPECS: Heat-hardened carbon steel, EXO-treated surface, silver finish. Fits mil-spec AR-15 upper receiver. Carrier does not have provision for auto sear trip.
