Riptor's Review of Magpul Industries MBUS Rear Flip-Up Back Up Sight Gen 2

Purchased for a set of backups for a build. I put gray and black XTM panels on it so I bought this Gen 3 front sight and a Gray gen 2 rear to keep with the aesthetic. Easy to install, easy to use, affordable, high quality...everything Magpul has been synonymous with. Only thing getting used to with mixing generations is the gen 3 front it actuated from the front of the sight and the gen 2 are actuated from side paddles. I usually buy the MBUS Pro steel sights but I wanted to try the polymer. 5 stars.
