The Crosman 2100 is scopeable. You will need a scope mount that is 11 mm not a weaver mount. 11 MM or 3/8" is common on air rifles and is narrower than weaver mounts. The scope rings are 1 inch as most all scopes are 1 inch tubes. I suggest a simple 4X10 scope would be sufficient for this rifle. It's inexpensive and won't break your wallet to buy one. You could go crazy and purchase an expensive scope that would cost you 10 times the price of the rifle but that is not necessary.
see the link below for a suggestion. This one has a slightly smaller tube but is communally used with this rifle.
Crosman has the information online. See the link below
Crosman still has parts available for this model. You can order directly from them. I've attached a link below of all the Owners and parts manual for Crosman rifles.

No, none do. But if you buy a Benjamin 392, or 397, (Benjamin is owned by Crosman) those come with a cheapie plastic lock. I've got 3 of them, wanna buy one?

Only if the airgun has a scope rail designed into the gun. You will also need an airgun scope not a firearms scope.
