barometric Posted December 28, 2009 Share Posted December 28, 2009 what MODEL M4 should I be looking at as far as choke, number of ports, etc? I aint young and am getting a headache trying to keep it all together. It looks like a changeable choke is desireable? (and the M1014 doesnt have that.) It looks like people want the 2-port tube- and there are some model(s) without that. Some models have a 3-position tube for possible collapsible stock,if i want to keep that option open, and Im not sure but I might have read somewhere that some models were MADE for collapsible stock, so the gun is properly drilled for that tube (but i dont know what he meant- are there some models that its a mod to try to add that 3-position tube?) ahhhh! Im trying to digest this all fast because my son is home on leave (SEMPER FI) trying to help me out, go to stores, etc. Quote Link to comment Share on other sites More sharing options...
