MBUS Back-Up Sight, Rear – Generation 2 GEN 2 - Mag248
The MBUS (Magpul Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The dual aperture MBUS Rear Sight is adjustable for windage and fits all mil-spec 1913 Picatinny rail equipped weapons, but is specifically tailored to the AR15/M16/M4 platform.
These are GEN2 MBUS sights. Excellent compatibility with all other standard AR front sights. These sights are super tough and extremely durable. Don't let the polymer technology fool you. These are extremely well designed and have been put to the test.
You will not be disappointed with these low cost alternatives to the old school heavy steel sights and the easily damaged aluminum sights common to the AR market.
Made in U.S.A.
