Things I liked: Purchased from PA. Mounted this on my Beeman R9 and have to say it has held zero for 1500 shots so far. Very easy to zero. I use the Mantis 1" scope mounts and they are very sturdy. I only paper punch at 45" in my backyard range but have shot it out to 35 yards, at times. If Mantis scopes are ever manufactured with increased magnification, i.e., 4-16-44MM or 4-16-50MM I will the be the first in line to buy one!

Things I would have changed: None really.

What others should know: The reticle is not etched. Mil-dots are very easy to use for holdover.

Things I liked: Picture is clear and there is no distortion around the edges. This scope is built very solidly and looks very high-quality on the outside.

Things I would have changed: The turret adjustments simply didn't work on this scope! I spent 45 minutes adjusting the turrets and could not get within 4 inches of the bulls eye at 10 yards. The turret adjustment knob simply stopped turning and would not adjust any lower. The windage adjustment didn't work either! Another issue is that the reticle lines are far too thick, but that's a design problem. I prefer thin lines over the thick ones on the Mantis.

What others should know: I am replacing it with a Hawke scope with the same specs (4-12x40 AO). It's a little bit more expensive, but I believe it will be worth it. I have not had any problems with my Hawke scope on my Marauder Pistol. Though the Hawke scopes cost more, I believe the quality control may be better. I regret giving the Mantis scope a try.

Things I liked: Good image,easy to focus.

Things I would have changed: Nothing.

What others should know: There were not much reviews on this scope but I took the chance because it looks fine and was at a good price.Beside I wanted more magnification than the usual scope (3-9x).I placed in a Benjamin Trail NP2 substituting a Barksa that after 1500 shots lost focus at 9-12x magnification.After a close look it is identical to the hammer 4-12x40 I put in my Hatsan 1000s vortex.May be is made by the same manufacturer.The good thing is that this Hammer scope is the only one that had resisted the recoil of this gun for > 5000 shots.If this Mantis works like this, will be amazing.I had shot around 100 times with it and is working fine. Will see if stay the same after 1000 more shots.

    Interesting that this is a recommended scope with rifle packages but no reviews and can't find much info on it. Anyone have any hands-on experience with this item?
