Things I liked: This mount produced full lock down support on the existing ?" grooved barrels for scope mounts and compensated for "barrel droop" with strategic shim placement. Would be ideal higher caliber rifles (.22,.25 and .22 rim fire). I would highly recommend this product...
Things I would have changed: great as is -- need not change anything
What others should know: Used on two .177 air rifles -- a Gamo Bone collector (1300 fps) and Savage (1000 fps). Both have grooved barrels for scope mounts. Had tried a variety of ?" scope mounts that continually shifted on both rifles (Drove me crazy!!).
Things I liked: Quickly reloading my break-barrel air rifles has been a problem but, now, instead of fumbling with the tin of pellets, I can rapidly reload using the Crosman Pellet Loader. This loader, unlike a competitor, has a metal tube that holds sixteen any style .177 pellets and has a convenient pocket clip. The pellet loader is easy to fill by removing the plunger and loading the gun just as easy by positioning the pellet loader over the breach and pressing the plunger.
Things I would have changed: Nothing I can think of.
