Have you ever gone mad trying to tune your AR gas system? You kind of had it for a minute, then it just disappears. The thing is, all those internal parts simply re-act to impulses started by gas from the round being fired. You must control the gas in order to control the system. The Seekins Precision Select Adjustable Gas Block helps you do just that.

Antacid Can’t Help This Problem

Most ARs come out of the box severely over-gassed, to increase reliability. When you run a 300 blackout adjustable gas block, you take control of the gas. By reducing the amount of gas allowed back into your weapon, you reap several rewards. With a Seekins Precision Select Adjustable Gas Block the felt recoil is greatly reduced, and shot recovery time is faster. Your weapon runs cleaner and smoother, resulting in less fatigue on those costly internal components. If you reload, when you properly use a 300 blackout adjustable gas block it will tame down your weapon, and you will have less banged up brass to deal with.

Tuning Is Everything

Installing a front adjustable gas block, means you don’t have to remove your rail to make adjustments. The Seekins front adjustable gas block gives you a revolutionary gas switch so you have truly tool-free field adjustment luxury. Running a Seekins adjustable gas block for suppressor applications lets you quickly switch components or ammo without major issues. With a quick flip of its switch, the Seekins adjustable gas block for suppressor use allows you and your weapon to achieve a Zen-like balance, and you can finally tune your rifle for optimal performance.
