I'm currently using this scope on a S&W M&P15-22. The optics are almost as clear as something in the $300 range, but it's just $29.99! It zeroed nicely and I've not had a bit of trouble out of it. Good luck on your decision!

I use some of the Pinty reflex sights on 22’s. Good luck with them so far and in the $20 range on eBay
