Overview

This front sight is built for shooters who want a low-profile backup sight that can be brought into use quickly when needed. Its metal-reinforced polymer construction with steel apertures keeps the design lightweight while adding durability, and the spring-loaded mechanism allows it to snap up and fold down with one-handed operation. It is intended for mounting on a handguard rail that sits on the same plane as the receiver rail, and it is not designed for use on a gas block. With the rear sight sold separately, it fits well into a modular setup where the user wants to choose matching components.

Pros

  • Tough, metal-reinforced polymer construction with steel apertures.
  • Flip-up design deploys instantly under spring pressure.
  • Can be folded down easily with one hand.
  • Matte black finish offers a low-profile, subdued look.
  • Designed for handguard rail mounting on the same plane as the receiver rail.
  • Rear sight sold separately for a modular setup.

Considerations & Trade-offs

  • Designed for a handguard rail on the same plane as the receiver rail, so it is not intended for gas block mounting.
  • Rear sight is sold separately, so this front sight is only one part of the sighting setup.
  • The sight is designed to lean to the rear and should not be expected to sit fully vertical when installed.
  • Deployed height is 1 3/4" and folded height is 5/8", so it adds a compact profile when stowed but still requires enough clearance when raised.

Suggested Comparisons

  • AR-15 iron sights
  • Flip-up backup sights
  • Handguard rail-mounted sights

Suggested Accessories

  • Handguard rail
