Recently got my first autoloader 12 gauge. It's a baikal mp155 with 3.5 inch chamber. I looked online and it seems to have an adjustable gas system but can find any instructions on how to adjust it. I mainly shoot 2 3/4 shells the only reason I ended up with a 3.5 inch changer is because I got it used for a great deal. Does anyone have one of these who could help me with the gad system? No manual came with the gun
