Stock PAS

Cut this orange piece

Add a piece of CPVC in the brown funnel piece for better air flow. I also tied a wire around the end of this to prevent darts from being sucked into the plunger tube.

Add a 1/2" CPVC coupler

There is empty area here that is bad for air flow, so fill it with hot glue (no after picture, sorry)

Add gasket for sound reduction and padding

Now attach a piece of CPVC to the end of the plunger rod (details in ASOF's write-up). Also, add a CPVC tee coupler (not pictured). I replaced the spring with a cut down [k26] spring.

Sand away a hole in the back of the body for the CPVC (new priming handle) to fit into - You want this to be a tight fit, you don't want the CPVC to be able to wiggle too much.

Cut down the stock for the CPVC to fit

Cut some 1.5" PVC in the shape of a grip. I cut an angle on mine to make it look better

Cut down this plastic part of the shell - This is so the stock is a bit more stable.

Cut some 3/4" PVC for a stock - Extra stems are to go into the gap of the piece we just cut down for more stability.

Attach these parts to your PAS with hot glue
Now to get into your PAS, you will need to cut the PVC down the middle. You can also just attach the PVC to one side of the shell, but I think this is more stable and the cuts aren't that visible with the final paint job.

Now to add the grip: Cut down a Longshot front gun's handle so it can fit more securely on the PAS

You will also need to cut down the PAS shell. (you can just glue it on w/o cutting, but I feel it's more stable with the cuts)
