To reassemble Safety Assembly, assemble gun to Stock, depress Safety Rod (140-34) with screwdriver, and press Safety
Assembly into place. Safety can be changed for left-handed shooters by removing the Safety Assembly and replacing
with the lever on the other side.
To replace a 140-31 Lever with a 140-31A Lever, the forearm must be modified.
This is accomplished by lengthening the existing lever slot in the forearm so it extends the full length of the forearm.
