What is in my on/off assembly space?

[koleah]

Back story:
Bought a 68Automag on Ebay, got it, put some gas to it earlier tonight, pulled trigger, nothing happened. Pulled it apart, pulled out "on/off assembly" to find out it looks like no other on/off assembly I've seen (I have another 68Mag and a Minimag).

Picture:

On the right is the normal on/off assembly from my other 68Mag, and on the left is what I pulled out from the space where the on/off assembly goes (part insertion order is top down/ what I pulled out first is at the bottom) (and yes, in both of them, there is another little white and slightly larger yellow O-ring, which is why I left them out of the picture)

Question:
Anybody know what this is and what its actually for? Is it another style of on/off that I'm missing a part to or something? Also, where's probably the cheapest place to get another on/off assembly for a 68Mag?


Thanks

Reactor valve apparently.... another question

I think I'm missing the second metal part. Does anybody have a reactor valve that they could make some measurements on the other metal part? I have a machinist friend who could probably make me the other metal part since it looks (from pictures) like its just a thick washer.

Maybe you should just buy a new AGD on/off assembly, saves a lot of trouble and is not that expensive.

There is parts missing from the reactor valve. I have some that have been removed from nonworking guns and replaced with the stock assembly to the customers satisfaction. Do yourself a favor and use the stock , but if you want to use it I can get you the dimensions.
