looking for info on the 2 orings for the inlet valve in the stock, that the gas resevoir valve pushes into
can't find it on the parts diagram
sadly 1 of mine had shredded and the gas dumps with only 1 in
can anyone help me save $200 on an AG m4 resevoir purchase by
helping me with a $2 oring
also looking for a replacement butt pad unit
