The Gas Block Tool Widget GBT-625

The Patented Saint Michael’s Armament (SMA) Gas Block Tool is unlike any other gas block tool. Any gas block that has an appropriately sized journal will fit. This makes installing a gas tube roll pin a breeze. Made of a solid ANSI 4130 or 4140 chrome-moly vanadium steel bar with a salt bath nitride finish, this is the last tool you will need to buy for installing gas tube roll pins. These are made slightly undersized to fit the widest variety of gas blocks. Once the set screw is tightened down, there is no movement of the gas block providing a secure platform from which to work.
Made in the USA
