The simplest and quickest way to do what you are proposing is to remove the gas tube from the gas block. Then turn the gas block around and install it backwards. In this manner the gas port in the block and the barrel will not line up thus no high pressure gas will escape the barrel. Returning the gun to SA function is as easy as reinstalling the gas tube and mounting the gas block in the proper orientation.
Sounds like a winner. Before I order my free float tube and some other goodies, I'll just verify with a proud Saiga 308 "manual action" owner if there are any issues. Would save me $27 in parts, plus some labor lol
Self-threadjack: Any issues with running a rifle or mid length free float tube over a low profile gas block assuming I don't plan on running irons? This is for a bit of 3gun fun while I can still have it, in Canada
