How do you dissasemble marines SP01 airsoft pistol?

Answer 1

I'm assuming you mean the Crosman SP01 Marines pistol.

First: go to Crosman.com. See if they have any manuals, disassembly guides, etc.

Second: normally I would say go to YouTube, but I doubt you'll find anything.

Third: Take it apart yourself at your own risk of destroying your gun.

I might ask: why do you want to disassemble the gun? Most of the time, when you do so, it invalidates any sort of attempt to return the product. I'm guessing you got this at a sporting goods store or online. My advice: if you got it at a store, return it to the store. If bought online, save yourself the time, money, and hassle and buy one from the store. It will end up being cheaper to buy a new gun than to send the gun back and pay for another shipping fee.
