TR Enabling introduces Obsidian, its latest offering in high performance coatings. Obsidian is a revolutionary coating that offers outstanding performance and appearance. This new coating recorded a coefficient of friction of .06, outperforming all other currently offered bolt carrier coatings. Because of its application process the coating is evenly applied, at a thickness of .0005”, on all surfaces of the assembly. TR Enabling’s Obsidian coating is rated at a hardness of RC70. Obsidian is rated to withstand prolonged exposure to extreme temperatures, far beyond that which a bolt carrier is exposed. Possibly one of the most notable features of this coating, for the average user, is the extreme cleanability it provides. Resisting carbon build-up and maintaining its performance between cleans is where this coating truly shines. After several thousand rounds, the shooter simply wipes the carbon from the surface. The coating can be cleaned by all conventional means (solvent bath, supersonic submersion and more) however, these methods are generally not necessary. TR Enabling recommends a light grease known as XF-7, however any popular firearm-rated lubricant will suffice.
