Gas blocks are small but very important to the overall function of your AR platform rifle. Distributing gas evenly and the correct amount ensures your firearm will fire. It allows your bolt carrier group to travel the correct distance at the correct speed/time. Gas allows for your spent round to eject and a new round to feed properly. As you can see, without a properly operating gas system, you will experience jams or worse.

We carry a huge variety of different gas block systems. There really isn’t a one size fits all system. It’s important to check the diameter of your AR barre first. We carry different sized gas blocks for many different diameter barrels. We also carry different styles including low profile and fully adjustable blocks.
