In the past few weeks I've been experimenting with a shitload of different breech designs, and I decided to try to engineer one around an LS clip. Then I looked over at my lonely PAS...
and this is the result:
It's essentially a PAS with an Angel Breech that uses LS clips.
Here's the breech assembly, closed:
Here it is open:
Close-up of the breech components:
The outer piece is 19/32" with 1/2" inside it (like an Angle Breech), and it's the part that moves. It goes back into the plunger chamber when you pull back the pump.
The inner piece is 9/16".
The shell is made from 1" PVC, and the "endcaps" at each end that hold the whole assembly together are 1/2" PVC couplers and 1/2" PVC, held in with screws.
The sliding arm:
The clip just snaps right into place:
This contraption performs beautifully. I can fire the PAS as fast as I can pump it with no jams or dart-cutting. The whole assembly is completely and easily removeable, too. And if I run out of clips, I can just use it as a standard breech, and single load darts.
The ranges at this point are in the mid 70's, but that's only because this PAS only has the stock spring, and the barrel is a little short. I'll be tweaking it further to see if I can squeeze 80's and 90's out of it. Shouldn't be too hard.
Finally my PAS can compete with it's big brother - the Doomsayer.

A couple ammo-holders I added a while back (2 on each side):
