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.
