Magpul MBUS Backip Sights
Magpul have developed a low cost backup iron sight (BUIS) called the Magpul MBUS (Backup-Up Sights). They are designed for the AR-15 platform but will fit any firearm with a picatinny rail.
The front sight will sell for $39.95 and rear sight for $59.95.
Hat Tip: MrMojoRising for the scanned advertisement.

Nice… especially since I’m pricing up a new AR build.
I’ll probably going to pick up those sight.
Magpul’s ACS stock is hot.

Definitely going to be getting a set for the Sig556, as the back-up sights that come on the rifle are terrible.
I really like these sights, any idea when they will be available for retail sale?
