One of the best micro magnifiers for the money - Meprolight MMX3 3x18mm Micro Magnifier w/ Quick Flip, QD Picatinny

I’m very pleased with this Meprolight product on my Tavor 7, paired with the M22 Pro.

Crisp magnified sight picture - no distortion or discoloration. Mounting system locks into position well behind primary sight. QD mount has nice latches that can be tightened down with included hex wrench. The magnifier also came with two colors of silicone shock guards which is greatly appreciated.
