With two removable Picatinny rails and four slots on each rail, the modular XTS Quad Rail Gas Block is easy to fit into your AR-15 setup. A gas block redirects gas from the port in the barrel through the gas tube then back to the bolt carrier group, cycling the rifle. A well-adjusted gas block can reduce shooting fatigue, help you shoot faster and allow you to shoot longer without the need to clean your firearm.

"Nice enough made in China gas block. Does not come with an extra roll pin. Good for replacing a gas block if you can keep your old pin in tact not so good for a build. Has 3 screws that stake to the barrel so better than the low pro gas blocks with just 2."
