Things I liked: Good fit on the factory dovetail. Numbered slots on the rail. Comes with proper wrenches for installation and good instructions. Good amount of elevation change, and the scope is not too high if mounted with low rings. Looks good on the rifle, which can't be said of a lot of other airgun mounts.
Things I would have changed: I would make this rail slightly longer, with more adjustment to the front. RWS 48 rifles have a short length of pull, which requires the scope to be mounted further forward for proper eye relief.
What others should know: This is a good quality scope base at a very reasonable price.
Things I liked: These .177 pellets are accurate from my RWS 34 and 48 rifles. They have great terminal effect on gophers (most pass through) and red squirrels. Recovered pellets are found against the hide on the off side and display expansion that has to be seen to be believed. Excellent hunting/pest control pellet.
Things I would have changed: Nothing.
What others should know: Very good shock; pests hit with these don't go anywhere; these are much more effective than wadcutter, domed or pointed pellets.
