We shave down and repark your standard A2 FSB to fit under most Handguards. We do not offer this service for non standard, surface hardened, milled FSBs, such as those offered on DD and Ruger rifles. This service also includes shaving off of the bayonet lug. You must remove the FSB from the barrel for this service. You will be charged $15 to remove the FSB if you send it attached to a barrel. Remember to send the pins if you are not sending the FSB w/the barrel. If your handguard isn’t listed, select DD. This is a functional/economical service to get a pinned type gas block to fit under your handgaurds. This is not artwork, and there will be visible sanding/machine marks in the metal.
Turn around for this service is 3-5 business days.
