Compliance Ready: Constructed from mild C1018 steel, the SMX can be easily welded if required for compliance with local and federal firearms laws and regulations. Enhanced Grip: The knurled forend provides a slip-free grip, aiding in installation, removal, and ensuring securement. Aesthetic Enhancement: The Stribog Muzzle Extension not only provides functional benefits but also enhances the overall look of your Stribog SP9 with its sleek and purposeful design.
