Ok, I am not that much familiar with gas guns so I could use some opinions about my idea: Buying a CO2 kit for the A&K SVD and converting it to a self-loading blowback rifle. Would it be possible? I have thought that i would have to machine the bolt from aluminium and maybe do some other modifications to other parts of the gun. Main reason for my idea is that there isnt any proper gas-blowback SVD's on the market. Thank you for helping!
