I have been wondering about the o-ring behind the top hat trick. It sounds like the B-Staley modification that is popular on Crosman pistols. I'm using the B-Staley mod on my 1701 pistol with good results.Sounds like a pretty good idea to me.
Unrelated......I just tried the oring on the top hat trick and it certainly quieted down the shot, and also slowed it drastically. Was just a few shots and no Chrono but they're hitting about a foot lower @ 100yards than they were without the oring. MUCH quieter report. Probably worth investigating further.
I have the TT shim kit on hand but haven't tried them yet. The kit includes 3 plastic shims. A single shim is 0.0645" thick, 0.478" diameter and a 0.25 hole in the center. Looks like they just limit the top hat/valve opening travel. An o-ring would also have a bit of buffering.
I'm not as fast as you on modifications but am trying to keep up!
