does the ban on having a higher shell capacity than 5 with a telescoping /pistol grip stock exsist today. march 09? are there any conditions concerning this rule? like location or before a certain date or after a certain date ...? second question is which of the m4 models has the heavy gauge bbl? 1014 or 11707, etc. i am "almost" sure the heavy bbl model comes with one choke installed(1014) instead of the model that comes with 3 chokes i believe. my m4 came with one choke installed in it but it does seem to have visible knotches for removal. for all i know , maybe my choke does'nt come out. i have not tried. i have to look to see if it came with a choke wrench. i cut out the label off the box but i must try to find it to be sure what model designation it is. it has a "tm" marking on the bbl and a "y01" prefix for a serial number. i figured the wright person would be able to resolve these questions for me. would be great to know the differences in these models as they have evolved. anything i can learn would be great. i can not find a running chart any place. seems the info on the benelli forum is sparatic at best and it seems hard to get all parts of these questions answered at one time. believe me i tried.
