Review: Great magnifyer - Well built and fits well. Remember to place magnifyer before the red dot. Great sight picture and nice and clear. Easy to fit. Not tried in rain yet.
Review: High quality - One of its standout features of it is the flip-to-side mount. This allows us to quickly and easily flip the magnifier to the side when it is not needed, without having to remove it. Another great feature of this magnifier is its durable construction. It is made of high-quality materials that can withstand the rigours of outdoor use, and the black finish adds a sleek, professional look. The mount is also adjustable, with a height of 37/40mm, making it compatible with red dot sights. The last advantage of this magnifier is its high-quality optics. It uses multi-coated lenses that provide excellent light transmission and clear, sharp images （as shown in the video )
