Overview

This folding front sight combines an integral gas block with a silhouette-style sight tower, giving an AR-15/M16 setup the familiar look of a standard front sight while keeping the profile low when folded. It is designed for shooters who want a fixed-height front sight that can be deployed quickly and locked open when needed, then tucked out of the way for a cleaner setup. The A2-type sight post matches factory height, so it is intended to work with factory-height rear sights. Built in steel and aluminum with a matte black finish, it fits barrels with a .750" O.D. at the gas port.

Pros

  • Integral gas block and folding front sight in one unit
  • Replicates the classic factory AR-15/M16 front sight tower appearance
  • Folds neatly out of the way when not needed
  • Standard A2-type sight post matches factory post height
  • Works with any factory-height rear sight
  • Fits .750-inch O.D. barrels at the gas port

Considerations & Trade-offs

  • Integrates the gas block and front sight into one unit, so it is not a separate railed gas block plus folding sight setup.
  • Designed for barrels that are .750" O.D. at the gas port, so fit is limited to that specification.
  • Uses a standard A2-type sight post at factory height, which is intended to pair with factory-height rear sights.
  • Folds out of the way when not needed, but it still adds a fixed front sight tower profile when deployed.

Suggested Comparisons

  • Flip-up iron sights
