Special Instructions

This magazine design does not allow for venting the remaining gas by pressing the knocker valve on the rear of the magazine. If you do this it can cause the gas route bucking to fly off the magazine. We advise that if you need to completely vent the magazine, you dryfire until the gas supply runs out.
