About this item
Impact resistant polymer construction provides light weight and resists operational abuse
Spring-loaded flip up sight easily activated from either side or by pressing the top
Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.
Clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 rail and provides the same height-over-bore as standard A2 irons
Protective wings shield the spring-locking A2 front sight post; Elevation adjustment tool included, but most aftermarket A2 front sight adjustment tools may be used as well
Product Description
Reliable Backup for Battery Failures: The Magpul MBUS Front Back-Up Sight Gen 2 is a low-profile, adaptable sight designed for AR15/M16 platforms.

Crafted from impact-resistant polymer, it withstands harsh conditions and is compatible with most Picatinny-railed handguards, providing the same height-over-bore as standard A2 irons. It's a dependable backup sight for tactical or emergency situations.

I'd be very careful about buying some of these sights. They are one of the most fraudulent copied sights made and sold as authentic when in fact they're Chinese knock offs. They're sold all over the Internet and the good ones even come with packaging and literature. Always buy from a reputable source, not from Amazon, AliExpress, eBay, temu or other sites like that. And no, I am not saying this particular sight is fake, I'm simply saying make sure any of the magpul flip ups are authentic before you buy them.
