These Crosman airgun models do not have any sort of base on to which you can fit standard rifcle scope rings, a fact often not know until the owner decides he or she wants to fit a scope!

Pro blox solve the problem by fitting on to the air gun to provide a "standard" air rifle dovetail grooved base onto which you can attach scope rings and then the scope.

So to be 100% clear you STILL need scope mount rings to suit 11mm base in order to set your scope up.

Each adapter block has 20mm of 11mm rail.

Sold as a pair.
