You send us any AR-15 platform barrel, any caliber, along with your preferred upper receiver, BCG and charging handle and we build you a custom pump action rifle upper assembly. Custom designs generally require some minor gunsmithing on your barrel and upper receiver as well as full assembly. Kit components are finished in a combination of DuraCoat matte black and Mil-spec annodizing. Other colors available for additional costs. Call or email to start a conversation about what we can do for your project. Pricing shown is for a standard carbine barrel.
