Correct Bob. When you order the Scheel roller delay it comes with the proprietary buffer tube. The slots that are pictured above are where the rollers sit.ACD what you are saying, just to be clear, the scheel wont work in the FX9 in stock form. It requires a proprietary buffer tube. Right?
Take Care

Most fx-9 bolts hover around the 12-12.5oz mark. So an 8oz buffer makes a big difference (the lowest I would use) from a factory 3oz. Every ounce up you go makes it shoot better and better until you hit the 22-24oz plateau. After 24oz there is no felt discernible advantage.7oz is too little IMO, from memory the FX9 bolt is ~11oz (whereas the Raven bolt is ~16oz).
11oz bolt + 7oz buffer =18oz, like you said ~22oz seems to be the sweet spot for PCC.
There is a TON of info on Blowback9 with data from his extensive testing that supports 22oz being where you want to be for non locking buffers in a PCC.
Mine was a little light in that case. I switched to a Kynshot hydraulic buffer and 2 weights which added another 11oz exactly (22oz total).Most fx-9 bolts hover around the 12-12.5oz mark.

Wow. Mine is 12.4. The others I've weighed all run the 12-12.5... gen 1 or 2? Wondering if that makes a difference.Mine was a little light in that case. I switched to a Kynshot hydraulic buffer and 2 weights which added another 11oz exactly (22oz total).

Gen 2Wow. Mine is 12.4. The others I've weighed all run the 12-12.5... gen 1 or 2? Wondering if that makes a difference.
If it's a gen 2 then I'm really shocked that there is a possibility of a 1.5oz difference in bolt weight
I might be interested. Which model did you order and what would the price be for it?anyone interested in the Kynshot, I have an importation of them comining in the next 2 weeks
