Got tired of the rattling play in the cocking arm of my prophet compact. Pulled the arm and broke out the calipers to see how much play was milled in. Had .013" of difference in the cocking arm and the milled slot it fits in. Broke out the feeler gauges and found .012" was a good fit. Drilled a hole in the end of thw gauge for the cross pin, cut the end flat to fit against the inner most edge, about 1/2" length total. Put it on the underside so the ball detent didn't lose any of its grip for keeping the handle closed. Lubed up and much smoother, less clunky cocking effort now. Did it all with tin snips, hand drill and emory paper to knock off the rough edges.

Great idea! I was wondering if a nylon washer would do the same, or some better wearing polymer. Hmmmm, .012 you say…

Just take off the shroud and start sliding feel gauges under the cocking arm to see which one takes out the slop and still stays smooth if you don't have calipers.

The feeler gauge is what it looks like finished when you cut on the black line and drill hole. If you look under the pivot arm you can see the feeler gauge under the cocking mechanism.

Weird, I have the opposite problem. Mine is tight and has now started to grind away at the bottom piece. I've only had it for about a month. May have to give AOA a call and see what they can do.
