 Optional Shim Set: The best 5$ you will ever spend! These stainless steel shims guarantee you perfect and hassle free barrel nut / gas tube alignment within the correct torque specs every time. For more information on our shims and a step-by-step guide to their use check out our video HERE.


Optional Bolt: We check every bolt / barrel for proper headspace before they leave our shop. For more information on our bolts click HERE.


Optional Bolt Carrier: Carriers ship assembled and include the gas key, firing, retaining and cam pins. If you purchase a bolt and a carrier, we will assemble the complete carrier group for you before shipping. For more information on our carriers click HERE.


Optional Gas Block Pinning: Only available for low-pro gas blocks. We drill and ream precise holes in the barrel and gas block then press-fit a dowel pin through so that the block will never shift on the barrel. Most military and police weapons are pinned. For more information on pinning click HERE.
