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.

Reviewer: Anonymous Person from MA  
Excellent customer service! Parts kit was missing trigger guard. I notified their sales team and they had it to me two days later. No questions asked. Great products and company!

5 of 5 Ar15 Obsidian lower parts kit October 29, 2017
Reviewer: Paul Soltero from Anaheim, CA United States  
Shipping was good especially considering its coming from the east coast and im in California. Now i have purchased 2 sets the first was good no problems but i guess people need to know what they are purchasing before u buy. Cause there was little to no instructions but thats ok , so again know what you are embarking on before you buy and cry. So that being said the 2nd kit was shipped with relative swiftness, but as i started to install the kit i noticed something. The 2nd kit which was purchased under same description and kit was not the same it was missing a spring the magazina catch release spring to be exact. So i replied to a couple of emails stating the situation but never have gotten a reaponse back at all. I'm sure just. Simple mixup possibly on my part but its ok . And yes i would rebuy from them and would recommend them to close friends and family. But i would like one question answered asap , What does “TR-Enabling” mean?  Thank you
