Tippmann ASA Regulator (?)

[devilzcall]

On my hunt for a cheap on/off ASA (in Germany) I stumbled upon this curious spare part.
It's listed in two shops for 14,99 and 19,99 and looks like it'd screw on a standard ASA mount and also allows for a dovetail to be used, but the listings give stupendously little information.
What really struck me as odd was the adjustment screw in the front. Is this a regulator, or just a shitty way to design an on/off?

It is indeed a regulator, although more of an LPR than a HPR. Pictured is the unregulated HP outlet, coming directly from the tank. On the passenger side ia a small outlet, threaded for a barb, where the pressure is regulated with the front screw.

This ASA/regulator can be used in sleeper Pneumag builds, for example. As to what specific Tippmann it was used with back in the day I can't say, but hey - this is the forum to get it explained in detail.

Used with the 98 E-Bolt kit.

As expected - an informed answer. Thank you, Sir.

So I could use one to individually adjust the pressure for my trilogy SF sear piston... Interesting if they weren't sold out. (Not sure if they were from the beginning or I just got unlucky)

The SF sear piston requires quite a bit more pressure to fire than the ram would need to cycle comfortably.

I used one for a pneumatic assist pump using an SF body. For the purpose of an e-bolt, they were terribly inconsistent which of course led to wild velocity swings, but for a pneumatic assist, or what you're doing, or pneumags (I hear they're popular for those) they work just fine. They're pretty uncommon and a bit pricy, so it would probably be easier to just run a second LPR off your bottomline ASA.

I had one and it was junk. The rail it comes with, the set screw pushes into, and bends the thin body of the reg, and then the piston assembly becomes stuck-ish. Very inconsistent. A CP style rail would fix the issue.

Holy shit it's natural newbie

Since this post has gotten a few comments, I wanted to let you know that I eventually tracked one of these down and put it on my Trilogy SF to separate the sear piston and front pneumatics. I like the idea that this would allow me to put the (e-) pneu grip on any cocker without changing any of the hoses, but I don't own another one currently and the whole assembly is very bulky. Also this not having an on/off doesn't help.

Funnily enough I actually did mount it with a PE rail worth about as much as the ASA because the original rail was missing.

hi devil, been digging through my archives, here is more info, hopefully helpful, to keep your cocker running smooth.

Thanks for looking that up! I have noticed the piston on my reg poking out quite far and not always the same, but since it only feeds the sear tripper piston, that inconsistency wouldn't be reflected in the markers velocity.

[Natural Newbie]

you are welcome. yes, in your case, as long as it has enough force to trip the sear, all is good.
