.458 SOCOM Rock River Arms Rifle with Black Butterfly Ammo

In our years of working with manufacturers to function, test and produce ammunition for the .458 SOCOM, we have built relationships with the manufacturers listed below. We not only recommend them, but have also created lines of communication between our service staff and theirs. By doing this, we provide the resources needed to assist our customers if they have function problems with our ammunition. In most cases, we also have a test rifle manufactured to their specs or have sent them ammunition to test fire in their new builds. Please use the manufacturers listed below with confidence and contact us. If you have any problems using our ammunition in their builds. If your problem is outside our scope of expertise, we will put you in touch with their .458 SOCOM service department representative.  For additional information and or test videos and photos featuring these firearms or barrels listed below, please visit our YouTube channel or our Instagram page.
