## 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.
