machspass Posted November 4, 2009 Share Posted November 4, 2009 I bought and installed a Socom guy produced magazine extension tube for my Benelli M4. It looks great and functions well, however I wanted a Standoff device as well. I bought a standoff device from Vang Comp Systems (the one used by the USMC) and was unable to install it on the end of the mag tube. It screwed about 1/3 of the way down and that was it. I had kept my old stock tube and it fit perfectly on that one. My best guess, after working with it for about an hour, was that the Socom Guy tube is ever so slightly larger than the stock tube. I am now searching for a new mag extension tube that will work with my Standoff. Any suggestions? Carriercomp? Quote Link to comment Share on other sites More sharing options...
