Product Description
The Strike Industries R.E.X. Riser is a low-profile, lightweight Picatinny riser designed for AR-platform rifles. Optimized to achieve ideal co-witness height when paired with the SI Reflex Exoskeleton (R.EX) mount, it works with A2-height sights using the included spacer or with Sidewinder sights without the spacer. Machined from durable 6061‑T6 aluminum with a Type III hard anodized black finish and secured by a steel clamp and hardware, this 3-slot riser provides a solid mounting platform for a wide range of Picatinny-compatible optics. It measures 2.09 inches in length, requires five rail sections for proper mounting, and weighs only 2 ounces.
