Sun Devil Manufacturing released their new Adjustable Gas Key at the 2015 SHOT Show. Dubbed the ADIGS (adjustable drop in gas system), their new gas key is compatible with both AR15 and AR10 bolt carriers. It’s adjusted via a self locking adjustment screw and is available in both a retrofit kit or already installed on one of Sun Devil MFG’s bolt carriers. Sun Devil MFG claims their new ADIGS helps reduce felt recoil and muzzle climb as well as help solve over gassing and cycling issues. The ADIGS kit retails for $59.95 over at Sundevilmfg.com.
