The G&G Bolt Cleaner is where the rubber meets the road. This tool was designed out of necessity and can clean the build up of carbon off the AR-15 bolt tail in under five seconds. Sometimes when you are at the range or out in the field, you don't have the time, equipment, or energy to fully clean your AR-15 rifle but you need it to keep working. Your life may depend on it... The G & G Bolt Cleaner was designed just for those times. It's smaller than the G & G Bolt Cleaner and Polisher, but gets just enough of the job done to keep you in the fight.
