Overview

Cryptic Coatings specializes in ultra-premium firearm coatings, and their Mystic Black DLC bolt carrier group represents the pinnacle of coating technology. The proprietary Mystic Black finish achieves an astounding coefficient of friction of just 0.01, making it four times as slippery as lubricated Teflon rubbing against itself. This is accomplished through Chemical Vapor Deposition (CVD) Diamond-Like Carbon coating, which provides exceptional hardness, wear resistance, and remarkably low friction even under dry or deficient lubrication conditions.

The Mystic Black DLC coating excels in reducing friction on sliding surfaces and increasing lubricity throughout the operating cycle. This translates to noticeably smoother cycling, lower operating temperatures, and easier cleaning compared to any standard finish. Carbon deposits wipe away effortlessly, and the coating's extreme hardness means it maintains its ultra-slick properties even after tens of thousands of rounds. The coating will not chip, crack, or peel, providing years of reliable protection and performance enhancement.

The steel version is machined from mil-spec 8620 aircraft quality steel with a shrouded firing pin and mil-spec chrome-lined interior. The gas key is chrome-lined and heat-treated for maximum durability, secured with Grade 8 fasteners, and properly staked. The bolt assembly uses Carpenter 158 steel, is shot peened, and is HPT/MPI tested. For competition shooters and enthusiasts who demand the absolute smoothest cycling and easiest maintenance, Cryptic Coatings delivers unmatched performance.
