Things I liked: adjustments easy, tight adjustments, looks good, price, no electronics or exposed knobs, parallax adjustable, shock resistant.

Things I would have changed: Not much for the price.

What others should know: I have used it about 500 rds with a R9 and haven't broken it yet. Next I am trying it on my R1. We'll see. I seem to bust many scopes on medium to magnum springers. These are not dial up scopes. Not many are. It would be a fantasy to think that at this price range you can just adjust your scope by target measurements. No doubt a good way to start but scope still needs to be shot in to the new adjustment, and play it by ear while slowly easing into your desired zero. Publications are recently filled with rifle shooters dialing in their targets and holding right on. Many, and I mean many of us, do not feel this is the best way to go (ever). Get the scope where you want it, leave it alone and hold accordingly. Range and adjust for wind as needed by holding off target, but don't mess with your zero. If this is the way you operate, and I feel it is the best method, this scope seems to fill the bill at a affordable price. Medium rings were tight but even with the adjustable objective cleared

Things I liked: The things I like: - The full knob sight adjustment knobs. Much better than the COIN OPERATED type. -The Mil-Dot Reticle. -The light transmission of the 40mm -The size is an inch or so shorter than models of similar power (minus the Bug Busters)

Things I would have changed: The reticle is not perfectly straight. I do not mean that it is canted, I mean the verticals line a slightly bowed. I expected a few degrees of cant so I prepped a wall level and mounted a bubble level on the tube. The cant is negligible but there is a slight bow. Since I am a backyard and short range shooter (Mostly under 30-yards) this is not a big issue but it exists and I notice it every time I shoot. Also, the tube is not as strong as a more expensive scope. I put small crimps in the side of the scope tube torquing to normal scope mount specs. Could be a little sharper at 8-9x zoom. The fringes get a little blurred at max zoom. I used it at 5-6x mostly.

What others should know: Overall, you get a lot for the money with this scope. I got it as a Combo with my Beeman R7 and have since moved it to my Gamo Maxxim Swarm since I like shooting the little R7 with globe sights. It has turned the Gamo into a half-inch grouper at 25-yards. If you want a perfect scope, pay more. For this amount of money, you get a good scope that holds zero and makes even a Gamo a single hole shooter. Speaking of holding zero, I have shot two-to-three-hundred rounds through the Swarm since putting it on and I have not had to rezero it.
