StrangerDanger Posted February 14, 2021 Share Posted February 14, 2021 Hold the unlock button in while doing the install. The stock should install onto the receiver extension at about 45 degrees rotated to the left. The stock should slide on, then stop. Rotate the stock 90 degrees to the right until the stock stops. Now you should be able to slide the stock up and down the receiver extension assuming you have a 3 position receiver extension. If you only have a one position extension, the stock will only pull out a short ways, then rotate 45 degrees to the left. Think of the adjustment notches as gears in a manual transmission.

StrangerDanger Posted February 14, 2021 Share Posted February 14, 2021 Can you post pictures of the receiver extension? Are the steel pins present in the collapsible stock? If you have another M4, try installing the stock on it to see if it functions correctly. Photo for reference. Note the steel pin just to the left of the unlock button.

StrangerDanger Posted February 14, 2021 Share Posted February 14, 2021 That spring looks mangled too. 1 Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted February 14, 2021 Share Posted February 14, 2021 It appears your stock came from the original M1014 1-2500 run. Those old stocks had Phillips head screws that held the cheek riser in place. The newer production use allen head screws. Be careful not to loose the lock washers that hold the cheek riser in place.
