if youre reading this, i got around to trying out the o-ring on the 392 transfer port. i did some testing on it and everything. i ended up gaining about 25 fps. i think i could get more if i had done a better job fitting the oring. it's a bit loose. i need more practice to work up some courage to do it to my brass valves
