Saint Michael’s Armament - The Widget - Gas Block Tool - .625
Manufactured by Saint Michael’s Armament
Saint Michael’s Armament (SMA) Gas Block Tool is unlike any other gas block tool. Any gas block that has an appropriate sized journal will fit. This makes installing a gas tube roll pin a breeze. Made of a solid 41V40 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.
