POF-USA Dictator Adjustable Gas Block AR-15, LR-308 with Rifle Length Gas Tube

The POF-USA Dictator Adjustable Gas Block provides the ultimate range of adjustability and versatility. All suppressors increase back pressure. As a result, your firearm will suffer premature wear of parts and see excess amounts of gas/carbon introduced into the action. This is due to a dramatic increase in carrier speed while shooting with a suppressor. With the addition of the Dictator adjustable gas block, you can now control the rate of fire, gas pressure, and the reliability of your rifle.
