JP Enterprises Adjustable Gas System

The JP Enterprises Adjustable Gas System is an integral part of our “recoil management” system. Most rifles are over-gassed, and the resulting bolt-slamming effect is a very significant part of the felt recoil impulse, which impedes sight recovery. We found that controlling the bolt velocity made for a much smoother shooting rifle. This easy-to-install gas manifold allows you to tune your bolt velocity to a particular load and optimize the feel of your rifle. If you enlarge the gas port, it is possible to tune up or down in case you want to use reduced loads or 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 at the range.

Price range: $78.00 through $158.00

JP Enterprises Adjustable Gas System

Description

Prior to purchase, please note the dimensions that we publish for each gas block to ensure that the part in question will be compatible with other components in your rifle. On rare occasions, you may encounter difficulties with fitting a low-profile gas block under a non-JP hand guard, and we can only guarantee compatibility among our own components. We have the opportunity to test many of the products on the market, but have no notice and even less control over any design, dimensional, or tolerance changes made by other manufacturers. It is therefore difficult for us to comment via phone or email as to the compatibility of our components with those of other manufacturers. In the end, ensuring the compatibility of parts rests with you, and some quick measurements prior to purchase can save a good deal of inconvenience later on.
