Things You'll Need
Instructions
Remove the rifle's bolt and turn the rifle over.
Use your 5/32-inch Allen wrench to remove the retention screws located on the front of the trigger guard and in the middle of the fore grip stock. If your rifle has a floor plate, open with the release button located at the front of the plate. Opening the plate will give you access to the forward screw.
Separate the stock from the rest of the rifle.
Place the rifle receiver into the replacement stock and install the retention screws.
