You would not think a scope you pick up at Walmart, in a clam shell plastic display, selling for $69.00 could function as well as others costing 3 times more. My Simmons scope 1.5 x 5 x 32 was dropped and became bent. Simmons scope had a diamond reticle, and the windage and elevation were not adjustable by fingertips. the scope new cost $110.00.
The first part of any purchase is a bit of research. CenterPoint is Crosman. http://www.centerpointoptics.com/
Checks of the web had most people liking the scope or at least the brand.
It came with weaver style rings and plastic shims. I had to use the rings that came with my SKS, but I did use the shims. Nice touch for an inexpensive scope.
1- Will the scope Zero, optics clear, red green illumination works
2- Will the scope hold zero over multiple days
3- Will the scope hold zero at 100 yds, dial in elevation change for 200yds,
Hit target 4-inch balloons multiple 4 targets, then reset elevation back a same number of clicks as you just set forward. Should stay true at 100 yds.
Testing over 3 separate days over a 10-day time span.
1 & 2 -Scope held zero at 50, 100 yds over multiple days.
Optics were clear on a sunny and cloudy day, red and green illumination worked fine.
3- Scope Zeroed at 100 yds, 3 shot groups confirmed. the ballistic table says the bullet will drop 7 inches. With the scope 1/4 moa that will be 1/2 at 200 yds. 14 clicks up. Clicks applied 14 up. Should aim for 200 yds. 1 shot – missed 4 shots hit 4 inch balloon.
Scope was adjusted down 14 clicks for reset to 100 yd. A 3 shot group confirmed the zero was held.
Step 3 was repeated multiple times.
This scope functioned fine. I like the illumination, Mil-Dot, the easy turret clicks to set the elevation and the wind. Comes with free flip-up lens covers and two batteries. The group below was 1.94 inch. The scope is mounted with a crappy mount. I did move up to a Choate drill/tap mount and the group came in at 1.5 inches.
