Currently available mods?

First, those who know how I type, no explanation necessary. To all you new guys, take 2 Aleve with a beer right now.

So. ~8? years of evolution and I am having the hardest time finding out who still makes stuff and what rates they would go for. I’ve been out of the loop for longer than most on this forum have owned an AF gun, this makes a nightmare for deciphering memories of past or current mods. For instance, I don’t think anyone here knows about the Sandman Chrony/endcap, which I think was a pinnacle achievement.
Perhaps having a living sticky of what people can do/make/buy?

Who is willing to create things for others (ie. milling work).

What my poorly researched and listed findings are.. Please correct me if wrong.

The guns from the factory have changed a bit. Valves, stock, o-rings, ect…
dyodat? is the current big valve maker?
Tony has a solid valve. Among other things, as always, great work.

Who has replacement breech’s or are factory good enough? What threading are the bolt handles so I can re-tap mine… I didn’t have this info on my BIG FILE backup, the formatting and misc info was lost.

Adam got copied by AF with a butt stock, but makes 2 great things still.

25 cal is a standard, LoL (who wouldn’t think AF would copy that…) Why are the barrels so short now in .25+cal? Modded valves that awesome? Frame flex from long barrels?

Are regulators any good with these guns?
Do full frame bushings decrease flex?
Reservoir adapter that moves it down an inch from inline (any good?).
Full body stocks, look great. even an ugly frame replacement would sell to the hardcore.
308? Yum, not sure if anyone makes any but maybe AF will copy it and name it Pterosaur? HA!
800/1000cc bottles? No more?
Remove choke and re-crown improve accuracy?
