Tried my new Saiga 12 19"bbl that I recently received from Centerfire Systems. It has 3 holes in the gas port, all unblocked. On setting #1 it would not cycle anything no matter what mag I used. Switched to #2 and it cycled everything fine depending on the mag used. Factory mag fed everything. Promag 10 rounders fed low brass #8 shells perfectly. High brass shells (slugs, buck, etc.) jammed on the second round, then fed fine. MD arms drum fed everything I stuffed into it. Recently converted to side folding stock and pistol grip.
