Magpul MBUS MAG245 Front BUIS






The MAG245 MBUS (Magpul Back Up Sight) is a robust and economical front flip up iron sight solution in polymer.  Extremely light at 1.1oz, the MBUS fits all Picatinny rail equipped weapons but is specifically tailored to the AR15/M16 system.  Folds to 5/8" tall and is spring loaded to firmly snap into up position when released.  The front flip up sight accepts standard AR-15 front sight posts (such as Tritium posts-NOT INCLUDED but optional).

-Tritium Front Sight Option-


Green front night sight for M16/AR15. Installation tool included. Green lamp is warranted for 12 years from the date of manufacture. Trijicon 3 Dot night sights are designed and assembled with the optimum combination of strength and safety. The patented aluminum cylinder and sapphire lens construction cannot be equaled. The brightness obtained from the tritium content is focused through the sapphire lens to give the maximum possible illumination. Because the sight blades are machined from steel rather than cast, their strength is unsurpassed. Trijicon night sights are the brightest, strongest and safest.
