I need some help . new to the forum but not new to the benelli. I got experience but these m4's are confusing. This is what I want .... what model do i need ??? skeleton stock.. don't care if it collapses, brugger/thomet, and 8-shot mesa. i'm going with a aimpoint compm2x.green j-tech laser on a side armor mount. and i am researching a surefire dedicated rail mount light on the brugger. what model number do i need and i prefer the heavier barrel even if i half to sacrifice on acessories , but i really want that 8 shot mesa. been saving for a year , and taxes are coming.
