With its low-profile design, this system enables the use of iron sights even when optics are removed, ensuring versatility in your shooting setup. The bases feature full-width and depth recoil slots, offering ample bearing surface for engagement with recoil keys, thereby enhancing stability. To ensure a secure mount to your firearm, the bases come equipped with Torx-style T-15 socket cap screws. It's recommended to tighten these screws to 25 in/lb. of torque for optimal performance.
