Magpul MBUS Gen 2 Front Flip-Up Backup Iron Sight — AR-15 Picatinny, OD Green

For a complete sighting system, yes — you'll need a Magpul MBUS rear sight too. Front + rear together gives you a usable iron-sight backup if your red dot fails. You can also run just the front with a fixed A2 rear, or just the front for a co-witness with an RDS.

The MBUS is A2-height which is the standard for AR-15. It will cowitness with most red dots mounted on absolute-cowitness mounts (T1/T2 height) or 1/3 cowitness mounts. With most red dots and a standard mount, you'll have either absolute (sight tip at dot center) or lower 1/3 (sight tip at the bottom of dot window) cowitness.

Polymer MBUS is lighter and more affordable. Steel MBUS Pro is heavier but more rugged for true duty/combat use where you'd actually drop or impact the sight under load. For 95% of civilian and patrol-rifle shooters, polymer MBUS is the right balance of cost and durability.

The MBUS front post adjusts for elevation via the A2-style tool-less adjustment ring (twist it with your fingers). Windage adjustments are made at the rear sight. Magpul printed the standard A2 dope on the manual to get you in the ballpark.

Magpul backs the MBUS with their limited lifetime warranty against defects in materials and workmanship.
