14.5" Carbon Supreme Rifle


We're proud to offer the most refined rifles on the planet. And after months of R&D, we've developed multiple configurations that cover a broad range of requirements, yet focus on one thing... Absolute dominance in the marketplace. EraThr3 gas guns are assembled with a free-float handguard, single-point cut 416R PROOF Research barrel, and a hand-selected group of top top-notch component parts. Meticulously built on our own billet receivers, each assembly is hand finished and proven on the range prior to delivery.

su·preme /so͞oˈprēm/
1. (of authority or an office, or someone holding it) superior to all others.

With blatant disregard to the masses, we set-out to design and build what "we" wanted in a modern-day AR-15. Rather than listen to some metrics pushing sales team, or rely on their boring market research data, we opted to do this one our way. And what we've found, is that those pencil pushers aren't always right. We're passionate about what we do, and what we do is win. Most every rifle out there is gonna go "bang", we get that part. This one just happens to do it with a new sense of style and greatness, one that you can have as well.

E3 Accuracy Guarantee:

Whether you are shooting steel, providing for the family, or hunting bad guys, we are here to support your efforts, and provide you the competitive edge required to prevail with a "Match Grade Rifle”.

To achieve the expected level of accuracy, every unit is hand-crafted with extreme attention to detail in its fit, form, and function.  Building an E3 rifle starts with a match grade barrel, chamber… and so on. We can guarantee the quality of our products and stand behind trusted suppliers to do the same, however we cannot guarantee the skill level of every shooter, quality of sub-par ammunition, and/or choice of optics & aftermarket accessories. 

Every rifle is tried, tested, and proven with "Black Hills Match" ammunition prior to delivery. Our AR rifles will not pass final inspection without having achieved a three-round, 1” or better MOA group @ 100 yards. This doesn't mean that our rifles won’t run with various types of ammunition, including custom loads or hunting grade products, it is simply no guarantee that they will. Tight tolerances equal tight groups. Simply put, we don’t build bullet hoses, and never will. Match grade rifles are just that, and should be treated as such. 

Rifles, just like your favorite pair of pants, have a lifespan. Even with easy use, and great care, things break, wear-out, etc. We stand behind our goods, and will support them to the end. However, we also expect that you understand the definition of “normal wear and tear”.

We highly recommend the training component to all of our customers, and follow the same advice ourselves. Being good at one’s craft takes good equipment, hard work, and dedication.
