You'll need to get your Materials which are
--A Screwdriver
--Hot Glue Gun
--Cpvc
--Goop
--Maverick
--Hacksaw
--Coupler
Start By opening up your shell

Next you want to cut down your Maverick shell like so.

Next hack it down so that way the two shells fit.

For the next bart you need to do this mod... http://nerfhaven.com...?showtopic=3666
Next you want to take your couplered Lbb and stick a peice of cpvc in it so its connected to the maverick air chamber measure and cut.

Now you baisically just glue and goop the crap out of it.

Now put everything back togther and and you should have a beast of a gun
