My mag tube is bobbed to half length, resulting in a "button style" wherein only a very little bit extends beyond the fore-end wood. It is hung from the barrel in the fashion of the MX/XLR series, with a factory Marlin MX mag tube hanger boss utilized and a corresponding slightly oversized dovetail slot cut into the barrel to accomodate it. I retained the rear carbine band, which was relieved for barrel clearance and D&T'd on the bottom for a swivel stud. About a thrid of the mag tube spring was cut off, and a new Hornady FTX friendly plastic follower was utilized.
The result is a solid MOA performer with factory Federal 170's and 1.5 inches with my preffered FTX bullets. The former tendency to vertically string shots has been eliminated.
