When you want accuracy and consistent performance from your AR-15, you can do a lot of tinkering to improve your results, but one of the biggest factors in the control of your rifle is how you handle the gasses that produce recoil, muzzle rise and even twist when you fire. Muzzle devices are great, but they’re only part of the story.
When you want to manage motion caused by the effects of gas on your rifle you need to limit backpressure too. As they come, most ARs run much more pressure than they need to cycle properly. The best way to reduce pressure and the backward force of each cycle is to add a quality gas block to your system. The 2A Armament Lightweight Steel AR-15 Gas Block is an ideal option for those who are looking for a lightweight, low profile non-adjustable gas block and prefer to stick with steel components rather than titanium.
2A offers this low profile 4140 steel AR-15 gas block to handle your gas limiting needs and still fit under most popular forends without creating concerns about clearance. The precision machined, the open-sided design is sleeker and lighter than many competitors' gas blocks. It won’t unbalance your lightweight competition rifle build like some larger gas blocks can. Control pressure and recoil without compromising the balance of your rifle or your choice of hand guards when you apply the 2A Armament lightweight Steel Gas block.
The 2A lightweight steel gas block applies easily to your barrel with a pair of stainless steel set screws. The blasted surface features a satiny black phosphate coating that stands up to corrosion and blends in perfectly with your Mil-Spec black components.
