Overview

Designed for AR-15 setups, this optic mounting system extends to the end of a carbine-length handguard and adds a raised rail position for a more adaptable sighting arrangement. It also protects the rifle dovetail rail while keeping the sight angled to fold rearward if dropped. That layout is intended to help preserve zero and reduce unnecessary wear in hard-use rifle applications. For hunters and shooters building a compact, practical carbine, it offers a purpose-built mounting solution without unnecessary complexity.

  • Raises the rail by 1/2", which adds height to the optic mounting position and may change your sight picture.
  • The rear-leaning fold direction is a design feature, but it also means the mount is purpose-built rather than a universal low-profile option.
  • Premium-priced accessory at $269.99, so it makes the most sense for rifles that specifically need this extended sleeve-style mounting system.
