Not bad at all for a "low end" ring - UTG Pro Max Strength LE Grade Quick Detach Picatinny Rifle Scope Rings

I've used these rings before on rimfires & spring / air piston airrifles with no issues, now using on a centerfire (.243) still no issues after 100+ rounds.

The look and finish is nice for that "tacticool look" while not being junky just for looks and are functional. Comes with non slip tape on the inside of the ring, an extra screw, and 2 allen style wrenches (one for the top strap screws, one to adjust the tension on the lever). Though called a "Picatinny" ring, it fits a weaver slot, so not actually a Pic rail size. No movement though on the weaver slot, just bump up against the ridge opposing directions on a Picatinny, they stay put. The cross bolt seems beefier than most HD rings by other manufacturers in this price range, i've had other manufacturer's at twice the price strip out before torque settings where reached, no problem with the Leapers / UTG.

Easy to remove and reinstall, with return to zero. No scope slippages / creep, keeps the scope in place very well when leveling reticle during installing.

Rings are hefty, if trying to build a lightweight or "smooth" appearing rifle, you may want to consider another ring, but if that's not a concern they are pretty fine for the price.

Keep in mind the "low height" is more toward other ring's medium size, they are about a size higher than other rings for the 6 screw variety w/ QD option.

Have had no issues with them either on the rim or centerfire, is my "go to" ring as they have performed even better than rings twice the price that are considered "medium grade". Obviously for serious competition I'd would go with higher end rings, but for regular hunting, plinking, range time there is nothing wrong with them.

Pretty surprised with the performance of the rings on all my rifles as they are considered "low end" in many circles, especially in the centerfire arena. Don't know how they will hold up on a Magnum caliber, but would try them.
