Instructions
Engage the rifle's safety and press the small button behind the trigger. The trigger group will release.
Pull back on the bolt and magazine; this will cause the magazine to pivot forward and out of the stock.
Remove the receiver and barrel assembly from the original stock and place it into your replacement stock.
Place the trigger group into the new stock and seat it into position with a light tap to the trigger guard's bottom.
Place the safety into the fire position. This verifies that the trigger group is re-engaged.
