Utilized for different types of ammunition and suppressed fire to maintain proper cyclic rates.
Regulator instructions
1. Start with the highest number on the regulator, #4.
2. Place one round in the magazine. Fire and verify a bolt lock. If bolt lock is achieved, use that
position.
3. If the bolt doesn’t lock back, rotate regulating plug to next lower position and repeat the process.
4. The object is to achieve the slowest cycling with bolt lock back. Using the lowest functional
setting will ensure efficient firing and prolong the life of the gun without over- gassing.
