Do the new production M4 collapsable stocks have identifying marks on them ?
I have an older style stock that had the marking on the right side and I bought a new what I think is a new Colt M4 stock but it has no markings on it. It slide fine on my old tube. I heard that non Colt stocks aren't interchangable. Thanks in advance for any help.

There is no marking on new style Colt stock.

  There are no markings on the new Colt's buttstock, but if it fits your original tube, it's the real deal.   The RRA and BM stocks aren't Mil-Spec and won't fit on a Colt's tube.
  I have the earlier Colt's Fiberlite stock and I bought 2 of the newer Colt's stocks and I like them a lot.

Actually, thats backwards.The Colt receiver extension is smaller diameter than the RRA/BM (the same). A RRA/BM stock will fit on a Colt tube, but a Colt stock will NOT fit on a RRA/BM tube.
