For a pop in arm, you could try wrapping a bit of paper tightly around the arm. Self adhesive paper is probably the best bet.

With the screw in type you might try putting a spring (underneath the arm) in the whole the arm is mounted in. This is a fender trick and allows you to have any arm mobility / lack of mobility you desire.
