Adjustable AR-15 Gas Blocks

Adjustable gas blocks are crucial for controlling the the amount of gas that enters your AR15 build. You can use Adjustable gas blocks, such as SLR Rifleworks and Superlative Arms to tune down an over gassed rifle. Being able to fine tune your recoil system is a major advantage because of the large variation in barrel port sizes and dwell time. Being able to control the amount of gas with a simple turn of a set screw will allow you to shoot a wide variety of under powered and overpowered ammo. Adjustable gas blocks are almost a must when shooting suppressed. Suppressors cause your AR-15 to be extremely over gassed and you can control the gas from the source, rather than using a heavier buffer or spring, which just puts a bandade on the gas problem.
