| JP AR Adjustable Gas System, .750" barrel
The JP Adjustable Gas System is an integral part of the JP “recoil management” system. It works for both AR-15 and AR-10 style rifles. 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. JP 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. Gas will be adjustable up to the full level you currently have and down as far as you want to match your load. You can even shut the system off if you want to manually cycle your rifle. If you have the gas port enlarged by a gunsmith, it is then possible tune the gas up as well as down in case you want to use reduced loads or in the case of some very short-barreled AR versions, which are somewhat ammunition sensitive.
The JP gas block also gives a very professional looking way to eliminate the front sight on flat top rifles. The intent with the rail on top is to allow for quick-detach front sight, but this also allows for use of flashlights, lasers or any other accessory item you may have a use for. Don’t be confused by cheap imitators. There are a number of copies of JP's product out now that are not as well made or are not adjustable. If it doesn’t say JP on the side, forget about it.
