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. Obsidian is capable of operating without lubrication, once the break-in period of 300 rounds is complete, though it is not recommended. TR Enabling recommends a light grease known as XF-7, however any popular firearm-rated lubricant will suffice.

Reviewer: Brant Randall from Imperial Beach, CA United States  
Shipping was fast. Finish is ice slick. And they included Xf-7 lube to get it started. Couldn’t be happier

Obsidian BCG July 12, 2017
Reviewer: Bubba DoDad from Raleigh, NC United States  
I am a returning customer.  I purchased a nickel-teflon BCG from TR-Enabling some time ago.  So, I was intrigued by the newer Obsidian BCG, especially since it has received good reviews.  

While I don't think it will affect functionality, the Obsidian BCG I received had some "rough" tooling marks on the front surface of the BCG.  In short, it appears QC overlooked the tooling marks, before it was sent to the coating process.  

Again, it probably won't affect functionality, but given the price, I would have expected better QC.  Lastly, despite this minor hickup, I fully support veteran-owned suppliers.  And, I am willing to overlook something that is not "perfect", as long as it performs to expectations.  

Sidenote:  my previous BCG purchase was flawless in its appearance and functionality.

I got this for my home defense build and have to say the quality of this bcg is absolutely superb. Super easy to clean and maintain even after 10,000 rounds, and I appreciate the lack of a logo; makes it look more professional.

Wow July 4, 2017
Reviewer: David Doster from Cartersville, GA United States  
The coating on this BCG is slick as a whistle.  Even with no lube at all, it glides through the fingers better than most regular BCGs that are fully lubed.  And the bolt came pre-lubed, too.  All in all, this is a great BCG and I don't regret one penny that I paid for it.  The free sample of XF-7 was much appreciated, and I'll probably switch over to that in my other ARs as well.  Shipping was extremely fast, too.  The guys at TR Enabling seem to be good, regular folks to do business with, and I'll definitely be back for my future AR builds.
