Did you ever want to step up and build an AR at home that would be at home in the hands of a professional? It's been said that if you're going to dream then you should dream big. There's something about holding the best in your hands and letting fate take you the rest of the way. When your AR build starts with a San Tan Tactical upper, luck may take a back seat to confidence.

Building A Better Mousetrap

In the quest for the ultimate upper receiver, San Tan threw away the mold, started fresh and set out to design the strongest billet AR upper possible. With the standard AR upper, most of the stress lives in the threaded portion of the receiver. However, the San Tan Tactical upper is engineered to redistribute stress across its entire length instead of focusing on one point. As a result, the entire upper becomes an intricate element of your build.

Professional Build At Home

Aside from the quality of the barrel, your weapons accuracy lives in its upper receiver. The degree of flexibility and rigidity determine the consistency of your shot placement. Of course, consistency is the heart and soul of accuracy. You absolutely have to do the same thing every time, in order to reap positive results. An average billet AR upper may not be up to the task. Okay, perhaps you're not competing on a national level but that doesn't mean you don't deserve top-level results. A great degree of performance comes from confidence, this is what you will feel when a San Tan Tactical upper brings the next round into battery.
