## Description

desertcart.com: Feyachi M37 1.5X - 5X Red Dot Magnifier Focus Adjustment Optical Magnifier with Flip to Side Mount, Black : Sports & Outdoors

Review: Exactly what I need it to be - This perfectly mounted and lined up with my Eotech XPS2 without any need for adjustment. I haven't had it mounted for over a year, in different conditions, so I can't yet speak to its durability, but it definitely feels solid. I have it set at 5X, and keep it there. I don't worry about adjusting my eye relief; variable magnification is a nice feature, and a great option to have, but I don't normally adjust my magnification in and out with a red dot - I'll switch to my LPVO for that. For zeroing my red dot and/or bench rest shooting, this is exactly what I need it to be.
Review: Great value - Only red dot magnifier offering 1.5x-5x adjustable, nice quality machine work clear lens holds zero on my ar 15 556 easy to use and install fit is nice and tight after 500 rounds still holding.

## Questions & Answers

**Q: Can you put it left or right?**
A: Yes you can...but...the button faces the wrong way.  It makes it unusable.  Flipping to the left is the wrong way.

**Q: Wondering if i should get the m36 or m37? is the m 37 worth the extra 20 bucks?**
A: I have only ordered the M37.  I cannot speak to the M36.  I have ordered these for 4 different firearms and am very happy with the value they provide.

**Q: Will this coexist with the Romeo 5?**
A: No, it can coexist with the red dot sight comes with .83 inch riser mount.

**Q: Do your magnifiers distort dot on 3-5x?  i tried 2 different magnifiers on a romeo 5 and a vortex sparc ar and both dots distorted into a line at 3-5x**
A: Mine does not. I have the M37 magnifier paired with the Feyachi V30 red dot, no issues at all except for my astigmatism. I’ve found that turning the brightness down helps that.

### ⭐⭐⭐⭐⭐ Get what you pay for.
*by P***L on February 19, 2025*

I have this five stars because it does what it says However, it isn’t super clear and at x3-x5 you’ve got to get pretty close to see through it. As such I wouldn’t use it on higher power guns. On my .40 carbine, I think it’s pretty good. As a budget magnifier behind a dot that I like, on a fairly inexpensive gun, I can’t complain AT ALL.
