Effective, efficient, and well-designed - Meprolight MEPRO FRBS - Self-Illuminated Flip Back-Up Rifle Sights

These polymer sights seem to be very well built, with very easy to access adjustments for windage and elevation. They are robust, and they have a unique and modern design to them. They fold, perfectly, out of the way. They don't feel cheap or flimsy, rather, they feel robust and very durable. I opted to add some loctite to the mounting screw, which hasn't come loose after nearly 800 rounds out of my Tavor 7. The tritium does its job, although the window for the vile seems very small. Based on what I paid for these, I was not disappointed. They are excellent backups, don't add much weight to your build, and they do the job you need them to do.
