Whats the diffrence between autocockers, By Year?

[Quackman71]

I have a 97 cocker, and i was thinking of getting a new body, to spurce i t up a little ;]
But i know the body has changed over the years...would i have to get all new parts to fit the new body?

[darklord]

I think all that's changed is

A) The size of the back block
B) body milling

Doubt any actual specs have changed.

They have changed the following since 97:

1) Body style
2) Front block
3) Back block
4) ASA

and obviously bolt size changes along with the back block. If you get a new body, I would recomend going to fireballmountain.com ...they have some KILLER bodies, and they come with a front block, body,back block, ASA, vert feed....and KILLER annos and mills, all you need is a new bolt I think. If Im wrong with any information, somebody please let me know.

The internal air chamber is larger on all post 2k cockers. They also operate at a lower pressure than old cockers (pre 2k). Post 2k cockers also had a different 3-way, and valve if i'm not mistaken.
