PDM 91 Posted December 27, 2016 Apologies in advance, because I know this has been covered elsewhere, at least in part. I have an M&P 15 sport, NJ compliant model (obviously). I have been having a heck of a time finding a sling attachment mount that will work without removing the stock. Tried the tango down pr4 and it simply didn't fit. Then ordered a tactical link two piece but just found out that I still need to remove the stock. So that got me thinking, why don't I just remove the stock and replace it with a fixed model while I am at it. Thinking about the ACE skeleton stock (I think it has QD points built in). My questions are: 1) removing the butstock -- is it simply a matter of drilling out the pin and pulling it off? Any other issues? 2) Any recommendations on a fixed stock other than the ACE? 3) Anyone familiar with the M&P 15 sport (original model) with any insight about milspec/non-milspec issues or other fit issues? And yes, I am fully aware of NJ law and have no intention of "unpinning" the stock on my rifle to make it adjustable. Quote Share this post Link to post Share on other sites
MacDan 20 Posted December 27, 2016 The Sport compliant model uses a buffer tube that is longer than a normal carbine tube (from what I have gathered). So if you want to change the stock, you need a new tube, it will not work in any other stock. I was going to get the tango down pr4 for my rifle, why doesn't it fit? The tactical link does not require removing the stock as far as I understood. It's two pieces and it goes around the tube. Quote Share this post Link to post Share on other sites

Displaced Texan 11,652 Posted December 28, 2016 You do not need to remove the stock to install the tactical link z-360 mount. I have them on all of my carbines. Quote Share this post Link to post Share on other sites
