Impact-Resistant Polymer Construction: The front sight is constructed from a high-strength reinforced polymer blend, making it lightweight and durable. It is designed to withstand operational abuse in various conditions.

Detent and Spring Pressure: The sight is equipped with a detent and spring pressure mechanism that keeps the sight erect when deployed but allows for unobstructed folding under impact or other circumstances.

Compatibility: The front sight can be clamped to most MIL-STD-1913 Picatinny/STANAG 4694 railed handguards. It provides the same height-over-bore as standard A2 iron sights.

Protective Wings: The front sight features protective wings that shield the spring-locking A2 front sight post, adding durability and protection.

Elevation Adjustment: The sight comes with an elevation adjustment tool, but most aftermarket A2 front sight adjustment tools can also be used for fine-tuning.

Elevation Adjustment:

~1.6 MOA (1.886"/100m) per click with a 14.5" sight radius
~1.2 MOA (1.367"/100m) per click with a 20" sight radius
