Comes with rings and shims.

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 elev 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.

Installation:

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 a inexpensive scope.

Test Sequence:

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 same number of clicks as you just set forward. Should stay aimed at 100 yds.

Results:

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 sunny and cloudy day, red and green illumination worked fine.

3- Scope Zeroed at 100 yds, 3 shot group 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. Computes to 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 wind. Comes with free flip up lens covers and two batteries.
