When i started this i knew that i wanted a coupler mod beacause i dont feel like ramrodding a dart everyshot and too lazy to do Pissbacon's Clip mod (even though iven been developing one like that myself).
But i found a problem as i cut the old barrel off you can see by this pic.

there is a space inbetween the plunger tube and a coupler. I wanted the barrel to be closer to the plunger to ensure a better seal and better range.
My answer?...THIS

I measured the distance that i needed between the tube and the outside and the distance "in" that a coupler goes I know the pic is bad put i epoxied the pvc in the coupler than i Gorrilla glued the coupler to the BBB.
After De-Rabiefieing it (gorrilla glue is really puffy and looks wierd when dry) it looked like this

Than i added a few more bells n' whistles and came out with this

PS:Sorry for some of the shatty pics
