We are registered with the BATFE as a Type07 manufacturer and headquartered in Southeastern Pennsylvania serving clients throughout the United States.

At our custom rifle parts shop, we build all types of high-performance, bolt-action, and gas-operated rifles. The arms we produce are designed, machined, and assembled to operate under the most demanding of circumstances, including competition, tactical operations, and deep woods hunting.

When it comes to firearms, equipment failure can create a range of unwanted scenarios, including disappointment and even disaster.

Our Growing Partnership to Help Save Lives

Our custom rifle shop has recently formed a growing partnership with Sky High for a very worthy cause. We have been very fortunate to have been graced with the presence of some children who are literally in a fight for their lives under care at St. Jude's Children's Hospital in Memphis, TN. Although very sobering, it makes us realize how lucky we are and how much we take for granted when being around these kids.

Steve Reichert, an Avid Customer

Steve Reichert, a rather well-known US Marine, proudly served his country during the war in Iraq. During this time, he was credited with the first mile-long sniper shot to neutralize an insurgent on the battlefield. Steve is also an avid shooter, and when he wanted the best, he called on us to deliver.
