  • If you need a custom length let us know! When ordering choose the barrel that is closest to the size you are looking for. Give us the details and we will be in touch!

  • Check Barrel Profiles This link will take you to the barrel profile page.

  • To reliably cycle both Sub-Sonic and Super-Sonic Ammuntion it is necessary to drill the port large enough to cycle Subs, and to be able to tune the size down to allow cycling for Supers. We strongly suggest you purchase an adjustable Gas Block for most reliable cycling.
