I Have not touched my Saiga 12 (Clone) in many years. Today as I was adjusting the gas block to relearn how it works I noticed it spun almost freely and the "lock" points at the settings were very loose and sloppy. I took it apart and found that the detent and the matching detent catches in the gas block itself are worn to hell.
My guess is I was adjusting it without pressing down the detent. Does anyone have any instructions on how to replace the detent?
I bought the gun in 2018 so I would assume it's one of the "post 2011" models that require drilling?
