Air america Apocolypse 3k or4.5k??

[Howdy]

Hey,

Sorry if this is the wrong section but this will be going on a mag. Im having a hard time finding out if my Apocalypse regs are 3k or 4.5k. Is there a specific way to find out. These are first gen SS ones. I assume its just a difference in burst disks but how do i know for sure? Can i just replace the burst disks with one for the 4.5k? I don't think they have a difference in internals as they are bricks and i compared it to a known 4.5k raptor rex and its 5 times more beefier and contains the same internals for the most part. Any help would be great!

Thanks
-Mike

I had the 1st generation Apocalypse and I still have the last generation Apocalypse. Both of them were 4.5K. I believe all the internal moving parts are all the same. The only thing that I think was different was the body. I believe the air passage design were improved as the models changed. I don't recall any marking on the 1st generation Apocalypse, but my last generation Apocalypse as marking on the burst disc.
