Things I liked:These shoot very straight in my RWS Model 48 Things I would have changed:The coating on the pellets is a bit messy...but it's a small price to pay for a good pellet. Not really a big deal.
Things I liked:1) The price is GREAT
2) Like Listerine...Says what it does, Does what it says. Things I would have changed:Can't think of anything. What others should know:After finding the true center of my scope, it shot 14" low. This base fixed that. When sighted at 30 yards, it shoots flat enough from 10-40 yards that I don't have to worry about compensating for pellet drop while hunting.
I'm very happy with this mount, especially after spending WAY too many hours messing with an adjustable one.
