K-SPEC Enhanced AR15 Carrier- Side Vents, Slotted Carrier Rails, Nitride

K-SPEC Carrier With Side Vents Slotted Angled Carrier Rails aka sandcutterFor enhanced functionality in adverse and rugged conditions such as sand, mud, dirt, and grime. These rail cuts are designed for debris disbursement, resulting in ultra-high functionality in the toughest conditions, including suppressor fouling and foreign contaminates. Strategically located angle cuts in the rails result in fouling and debris being moved into noncritical areas that are not in contact with the receiver and do not affect the function of the firearm. Designed to function reliably in the toughest conditionsAngled Carrier Rail Cuts for flawless function in adverse conditions and prolonged suppressed use aka sandcutterFull Auto ProfilePermatex added between Gas Key and Carrier Mating SurfaceCarrier- 8620 steel, outside rails, bolt runs, and gas bores ground to .0002 tolerances, nitride finishGas key - 4130 steel, heat treated, secured with T25 torx fasteners, torqued to spec, staked with hydraulic staking machine9.5 oz Machined in house and assembled using only the finest steels and components.
