NCswamp13 Posted July 28, 2020 Share Posted July 28, 2020 Was playing around with my new m3 last night and realized after I removed the stock it was threaded on the back of the receiver just like the m4, i have a field stock for my m4 that I wasn't using so I tried it out and low and behold it works. Besides some slights differences in contour which doesn't affect the feel, it works perfectly. Sorry for the bad pic, I'll take more when I get off work.
