There is a takedown latch (lever) under the forearm. Pull it down, then remove the forearm from the barrels by pivoting away. Carefully slide the lever on top to release the barrels in the usual manner of breaking the barrels open. The barrels can then be lifted off the lug from the frame as you break the action open.
