SLR Rifleworks Adjustable Gas Block

Sentry 0.936" ID / Melonite QPQ finish 4140

An adjustable gas system is an integral part of your “recoil management” system. Most rifles are over-gassed and the resulting bolt slamming effect is a very significant part of the felt recoil impulse. We found that controlling the bolt velocity made for a much smoother shooting rifle while reducing muzzle rise and minimizing the abuse of critical components. This easy-to-install gas manifold allows you to tune your bolt velocity to a particular load and optimize the feel of your rifle. It is possible to tune up or down in case you want to shoot reduced or hot loads, run suppressed or unsuppressed, or open up your gas port in the case of some very short-barreled AR-15 versions, which are somewhat ammunition sensitive. You may also shut the system off if you don’t want to chase brass or give a hot brass shower to your neighbor on the firing line.
