Secures to barrel with included setscrews. Low Profile 2 is shorter and lighter than the Low Profile, and allows rifle length forearms to fit carbine-length barrels.

    Item Code: #453217907

    Availability: In stock

    Makes Rifle Run Cooler & Cleaner With Less Felt Recoil Kit has everything you need to replace the standard gas system in your AR-15 and convert it to a reliable, positive-cycling, gas piston system. Eliminates venting of hot gases and powder residue into the bolt carrier and receiver for reduced fouling and less wear on the action. Feeds more smoothly, maintenance is easier, and the gun runs cooler, too. Short-stroke piston shaft eliminates concussive gas expansion in the upper receiver for less violent cycling and reduced felt recoil. Easy to adjust for three levels of gas release: normal fire, firing with a suppressor attached, or a single round fired without cycling. Picatinny rail on the gas block provides mounting space for a variety of front sights. Installation requires removal of original gas block, but no permanent alterations to barrel or upper receiver. Remove the piston system at any time and reinstall the original parts. Replacement handguard provides extra internal clearance for piston rod and has internal shield to protect your hand from heat buildup during sustained fire. Separate models for three popular gas system lengths:Carbine, Mid-Length, and Rifle. Pistol kit comes with a Samson 4" Free Float rail.

    For Easy Adjustment Of Gas Flow In The Field Or At The Range Refinement of Syrac's original adjustable gas block enables the shooter to fine-tune gas flow and rifle performance in the field. Designed to fit under free-floating handguards, the block secures to the barrel with two setscrews. The Gen II model eliminates the Gen I's release button, so you simply turn the gas adjustment setscrew with the included Allen wrench to one of 18 pre-set click detent positions. Click detent automatically locks in your setting; also makes "dialing in" predetermined settings for different loads easy. Standard Low-Pro models have setscrews on the underside; requires dimpling of the barrel. Clamp-On model wraps around the barrel and is secured with two side-mounted hex head cap screws.
