As long as it has an 11mm ring mount then Yes. And I think it does, or you can order 11mm scope rings for the scope.
Yes. I currently own an LG Optimus V and it has a Body Glove Case on it. Any case that is designed for the Optimus S will fit the Optimus V.
The R-76 is NOT scopable so a Red Dot will NOT fit on it.
Cost prohibitive
Yes
Yes.
The Crosman 357 is modeled after the COLT PYTHON. If the Python fits the holster, then the Crosman 357 may also fit. Your just going to have to try it.
I have not tried this particular combination, but the 459 is the same size as a regular 22 scope mount. (I own 2 of them) I've mounted scopes on both of these mounts and I see no reason why the Gamo 650 shouldn't fit.
Yes, all scopes that fit on the 7/8 rail will fit on the salvo.
Yes and no. BSA scopes fit on a couple of grooves machined in to the top of the air chamber. These grooves don't exist on the BB but you can get blocks that have the grooves on and could glue or otherwise fix this block on the BB then the BSA scope would fit.
Any 12 oz C02 cylinder will fit. They are all made the same.
In Cabela's Outdoor Adventures, you can equip different scopes by accessing your inventory or weapon customization menu. Select the firearm you wish to modify, then browse through the available scopes in your inventory. Once you find the desired scope, select it and confirm the attachment to equip it to your weapon. Make sure to check compatibility, as not all scopes fit every firearm.
