Armorer’s Services

We’re proud to offer the services of factory certified technicians and qualified armorers. We can install triggers, replace sights and do many jobs that are only to be performed by an armorer. At our new service counter, you can watch us mount your scope, install and time your muzzle device, replace furniture and much more. We charge reasonable flat rates for our work, which is all done with correct tools and procedures. Most accessories purchased from us are typically installed free of charge, as a courtesy.
