My previous tactical shotgun was a Mossberg 590 and when I kept it loaded with 8 rounds, it would not cycle the last round or two after 6-12 months even using Wolf springs. The spring was compressed too much for that duration and it lost some of its tension, so I made a habit of replacing the Wolf spring every 6 months. I wonder about loading all 7 rounds into an M4 with full-length magazine tube -- IF the spring will need replaced once a year or so? MikeSp

Obviously, quite a number of M4 owners are adding the full-length tubes that the M4 was designed for - but isn't there some concern about legalities? What if the owner's M4 was used to protect the family and a LEO noticed the full-length magazine tube? Or what if, in this scenario of the M4 being used to protect a family and the perp was wounded and sues the person because the M4 did not meet BATF standards? Yep--I want an extended tube, but the legal concerns override the practical concerns... MikeSp
