E3 Accuracy Guarantee:

Whether you're shooting steel, providing for the family, or hunting bad guys, we're 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’s 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.

BrillantReview by Dr. T.
I purchased this rifle to get my hands on the receiver set and I am very happy the whole kit. It is extremely light with carbon wrapped barrel and all. All components are of the highest quality and finish. The titanium small bits are receiver the best ar components I have seen. But the receiver set completely sets it apart. This set is absolutely BRILLIANT! Than you EraThr3. (Posted on 4/6/2016)

I purchased this rifle to get my hands on this receiver set. The entire rifle is excellent, from the carbon warped barrel to the titanium small bits. The receiver set however is absolutely brilliant! - Dr. T. (Posted on 4/3/2016)
Brilliant!Review by Dr. T.
This rifle has not spent night in my safe since I bought it. It is so meticulously crafted I just can't put it down. And, so incredibly light. Part from the carbon barrel which not only looks great it is also precise. The titanium small bits are so fine. But the receiver set, the receiver set is what makes it. So trim and so light. I bought mine just to get one of these receiver sets. This receiver set is absolutely brilliant in design. - Dr. T. (Posted on 3/22/2016)
Brillant!Review by Dr. T.
Mine has spent more time out of the safe lately than any other I've built myself. This thing is incredibly light. It is meticulously assembled and mine arrived flawless. The titanium bits are so cool. The carbon wrapped barrel is bad ass. But the receiver set what sets it apart from all others. This is the best use of billet manufacturing for an AR receiver I have ever seen. Too many billet receivers are bulkier than the forged counterparts. This thing is light and trim. Industrial engineering art at its finest. Just brilliant! (Posted on 3/16/2016)
