Now let's start with getting your supplies.
What you'll need:
►1/2 inch CPVC
►1 1/2 CPVC coupler
►One pipe cutter (not pictured)
►Adhesive of your choice (not pictured)
►And of course your favorite set of screwdrivers
Start by removing the two orange rings. This was easy for me because I was able to simply twist off the cap on the front of the gun, and used a screwdriver to remove the ring on the pump's end.
After the rings are out of the way, let's open the gun up. Use your pipe-cutter to cut on the line where the AR is placed. (thanks to man_with_many_guns for the internals pic)
It should look like this when you're done.
Next, I've hot-glued the trigger spring like many before me have done.
Cut roughly 1 7/8 inches of CPVC and wrap it with e-tape until it fits snugly in the cut barrel.
If you didn't guess, slap that coupler on the end of the pipe. Make sure to glue everything in place then set it to dry.
After you've put that back in the shell, let's take a look at the pump. I took out the pump...rod and found these four corner-esq. pump stoppers. Let's sand these away and extend the length of the pumping distance roughly a quarter of an inch. I've not seen anyone do this in any of the mods before mine, but I might've over looked something.
This is the pump sanded down. I've actually found doing this slight extension to the pump length enables me to have to only pump it three times instead of the usual four while still having maximum ranges.
And I have of course plugged the pump. (I apologize for the slightly blurry pic)
Once you've finished that, put all this pack into place inside the shell.
As you can see, the coupler is flush with the original shell and it's a perfect fit!
