If you look at the very back of the receiver on the left side there will be a small tip of the bolt stop showing in the left bolt guide channel, push it down while the bolt is open and pull back on the bolt. Should fall out .
. to remove the bolt on this model you must lower the tube assembly,there is a screw under the stock, remove stock first.
