Simple in its execution, yet robust and reliable, the revolutionary Strike Latchless Charging Handle offers forged 7075 construction, efficient side gas venting, and a solid, comfortable interface for the user. Reliable receiver lockup is achieved through a novel hidden spring mechanism that uses the Charging Handle insertion slot in the upper receiver charging handle channel. This channel features a natural radius that will not wear rapidly like the external, 90-degree edge of the standard CH latch area of the upper receiver. The flat spring bearing surface is much larger than a steel ball bearing, spreading force and wear out over a larger area. Increased service life is one benefit of this type of system, as is the comfort and peace of mind that come from a lack of moving or external components that can break or snag/catch on your gear and foreign objects. The solid aluminum construction is durable and provides a solid mounting point for the ISO Tabs, an add-on component that increases surface area for those using large optics and/or gloved hands. Note: For standard mil-spec AR15 rifles only. Not rated for suppressors and/or full auto fire. Not for use on SBRs or pistol length barrels (<14.5"). This model has a black finish.
