New to the forums and new to the AR platform after years of assorted center fires. I picked up a new compliant M&P Sport and have a question and comment about the stock fitting over the buffer tube. The phony stock adjustment lever does nothing and the stock is held in place by 2 pins, one on each side of the stock. After looking at this it sure looks like they took a normal sport, which is the SKU number of the rifle I have. This model has the permanent pinned,welded muzzle brake, and they put a commercial phony S&W compliant stock over it and pinned it in place. The stock was rocking up and down more than a little so I removed the allen bolt which was only into the plastic stock holding the phony lever and not touching the buffer tube. I measured for a drop in pin to put into the stock and matching buffer hole and once I cut the metal pin and fit to the proper length I put the allen bolt back in which now pushes on the pin and buffer hole and the stock is now tight. When you look at the buffer tube from the stock opening in the rear the stock is very loose on the buffer and was causing the rocking motion. My plan was doing no mods to this sport and shoot it into the summer which should give me minimum 1000 rounds and total familiarity on function, ammo and such, but replacing the terrible fitting stock is something I want to do sooner than later. I'm assuming this is a mil spec buffer, if anyone can comment on that. Also if anyone has any comment on the Magpul fixed carbine stock as a replacement. Thanks
