"When I was deployed we had a saying, "Ounces equals pounds." The amount of extra weight we carried around equipment wise was always a limiting factor when it came to movement. I wish I had a gun like this when I was deployed. The weight, accuracy, and reliability are second to none." Johnny Primo


Spec'd personally by Mr. Primiano.

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. This doesn't mean that our rifles won’t run with various types of ammunition, including custom loads or hunting grade products, it's just simply no guarantee that they will. 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.
