Hey gang. I love my stock barrel, but its a little short.

I would really like to get myself a deadlywind, but the back of the barrel has that plastic that will hit the actual pump handle. I've heard that Colin makes them specific for the phantom, but I would prefer not to buy an undercocking kit and I havent really been able to find much info about them.
My thoughts were to modify the pump handle(perhaps make the hole a little bigger in the back to accomodate the plastic) so that it would fit around that plastic, or perhaps cut a section out of the pump handle to help with this.
Anyone have any experience or knowledge as far as any of this goes?
Any and all information would be most appreciated.
