Hello everyone,
I've been trying to find the difference between the S-12 and S-20 gas block and from what I can find all the internal parts are the same. But are the barrel OD's where the gas block presses on the same? Can someone measure the barrel OD (or block ID) on a saiga 20 for me?
If there is a difference, could a saiga 20 block be reamed out to 23mm (for the saiga 12)? From the pictures I could find it at least looks like they used the same casting for both models, so I would assume it could be made to work.
Thanks
