Hi all, I recently got a Magpul CTR stock, but it is a mil-spec size so none of my DPMS or Bushmaster commercial buffer tubes will fit it. Would like to purchase one or I have a commercial tube I'd trade if you need one. New or Used, it doesn't matter. A CMT, LMT, Stag, VLTOR, or Colt buffer tube would work as they are all mil-spec sizes. Thanks!
