  • Great scope for the money
Color: Black
I received a water filter instead of a scope on the first try. I returned it and l’m happy with the actual scope. Compact. Clear glass and good illuminated reticle. Easy mount up and dial in. This is an excellent scope for the money. I would buy this scope again.

  • Great inexpensive scope
Color: Black
This is not an EOtech or Trijicon. That being said this is a phenomenal inexpensive scope. This is a perfect scope as a starter or for an inexpensive build. I mounted the Monstrum 3-9x32 AO on a custom 10/22 to be replaced eventually. Pretty sure I’m going to keep this one on it. Parallax is adjustable which is great at this price point. Zoom is low enough for inside 10-15yards and out to 200. Zero has held after 4-500rnds of .22, minimal adjustment. Eye relief is pretty good, didn’t measure but you can use with an AR. Glass is decent, not like my high end ones, but that’s why they’re 10x the price. Windage and bullet drop work well and are consistent. Illuminated cross hairs are nice in both green and red. Reticle is great. The zoom throw is great, large enough and replaceable if you wish. Very well built scope, I’ve beat it up pretty good and it’s delivered consistently. All and all, a great deal for the money. I’m pretty sure it would hold up to recoil on AR. Well made piece of glass as a starter or otherwise. Do not hesitate ... show more

  • Typical Monstrum optic
Color: Black
Bought this because I have 2 other monstrum scopes on a .350 and .223. These are some of the best scopes for the money. My .350 with a good barrel and Monstrum 3-9 will have 3 shot groups touching all day. Purchased this one for my Legacy Howa Citadel .17hmr and can’t wait to see the grouping with this. ... show more
