JP AR-15 Fixed Front Sight Assembly with Adjustable Gas System for .750" barrel (Black Stainless)
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 AR-15 type rifles are over-gassed and the resulting bolt slamming effect is a very significant part of the felt recoil impulse, which slows 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.
This Front Sight Assembly houses the JP gas adjustment system and the front sight post in a very high quality fixed front sight housing made of 416 Stainless with a Black QPQ finish. It includes the complete front sight assembly with a standard front sight post adjustable for elevation. It is secured to the barrel by tightening two hex-head screws which tighten the housing evenly against the barrel to ensure an excellent gas seal.
