Kaw valley .625 dimple jig - Kaw Valley Precision AR-15 Gas Block Dimpling Jig

Works great on all .625 gas block journal barrels. I use superlative arms gas blocks and their spacing is .500 I learned this as another site recommended a gas jig with that block and sent me a .375 jig for a .500 spread. That was my first run at using a jig. This jig works on almost any size spread you could think of plus locks in either at the existing dimple or off the gas port itself. Fast and easy.
