Magpul MBUS AR 15 Front Back-Up Sight Gen 2 – MAG247



The Magpul MBUS AR-15 Front Back-Up Sight Gen 2 is a reliable and durable backup sighting solution designed specifically for the AR-15/M16 platform. Crafted from impact-resistant polymer, this front sight is built to withstand the rigors of demanding shooting conditions while remaining lightweight and easy to operate.

The front sight features a spring-loaded flip-up design, allowing for easy deployment with just a small amount of pressure on the release tabs or by pressing the top. The polymer construction resists impacts and operational abuse, ensuring stability and accurate alignment. Compatible with most MIL-STD-1913 Picatinny/STANAG 4694-railed handguards, this sight provides the same height-over-bore as standard A2 iron sights.
