My goal was to create a neat, clean BBB with full modifications, no dead space, and appropriate reinforcements. I also wanted to keep it as fool-proof as possible. I give you:
The Big BAMF Bow
This mod is extremely comprehensive, so I’m gonna break it down into steps. Please note that this mod involves doing lots of permanent alterations to your gun. Don’t start unless you’re sure you can finish, and do it properly.
Step 1: opening the gun.
Open the front half of the shell. See these tabs? Put them and their associated springs in your "tiny annoying parts" holder.

Now for the challenge: the inner shell. This thing is glued together, here.

There are also pegs and slots that are glued into each other, and usually end up breaking off.
Now, you don’t want to break the gun, so don’t jerk on it. Any pressure applied should be firm and steady. Lots of small (and not so small) parts will get jostled out/removed while you’re trying to open this sonofabitch, so keep up with them. The catch, the catch spring, and the trigger spring are small and important; watch out for ‘em.
Remove all the screws, and open the shell as much as you can. Insert a small screwdriver into the crack between the shell halves, and slide it forward, spreading the halves as you go.

The idea is to overwhelm the glue joint while avoiding damaging the surrounding plastic. TAKE YOUR TIME.
Step 2: Internal PVC Coupler
Take out the front of the plunger tube, and remove the air restrictor assembly. You don’t need any of it.
Cut off the stock barrel.
Dremel out the large orange piece until 1/2" pvc fits through it. Keep checking; you don't want to remove too much.


Cut a ring from your ¾â€pvc coupler, about 3/8†long.
Now smear a good amount of goop around the barrel opening. Don’t be shy; this needs to be strong. Take your reducing bushing, and push it down into the goop, removing any excess goop from the inside of the bushing. Get it more or less centered and straight.
