[Eye Catcher 1]

I shot a few 3 3/4dr 1 1/4oz outta my COMP barrel on a Trap receiver. It cycled the bolt so fast it would either close on the empty shell (shell catcher installed), kick the shell out through the shell catcher, or kick the shell out through the shell catcher and re-close the bolt.

I dont know if I would recommend it. Prob a lot of premature wear.
