Back in April (2009), DefenseReview has published a short “heads-up”-style article on the FailZero AR-15 Basic Kit, which is a bolt carrier group (BCG) and hammer upgrade kit with a proprietary and patented self-lubricitous/self-lubricating nickel-boron (Ni-B) coating that the company calls EXO Technology.

In the video below, DefenseReview.com contributor Chen Lee a.k.a. “SMGLee” performs a short demonstration of the FailZero “AR-15 Basic Kit” in a desert environment. The demonstration weapon is comprised of a Colt LE 6940 16″ 5.56mm NATO/.223 Rem. AR-15 carbine upper receiver mated to a full-auto registered full-auto lower receiver. In the video, Lee fires two magazines (2×28 rounds) through the weapon on both semi-auto and full-auto (burst fire) with absolutely no lubrication. After he empties the first magazine he pours sand over the weapon, shakes it off, and fires another 28 rounds on semi-auto and full-auto. The video is a bit over-exposed, but it’s good enough for you to see the FailZero Kit in action.

Here’s the full list of AR-15 parts and features in the kit:

– Case Hardened, Shot Peened and MPI Bolt (Magnetic Particle Inspected)
– EXO Coated Bolt (40% more wear resistant than Chrome with a very Low Coefficient of Friction)
– Mil-Spec Gas Rings
– EXO Coated Carrier
– Chrome Lined Gas Key
– Gas Key Hardened to USGI Specifications
– Grade 8 Hardened Fasteners
– Blue Extractor Insert
– Mil-Spec Staked Gas Key
– Firing Pin and retainer
