Normal 1/2'' coupler (CPVC)
T-Coupler (1/2'' CPVC)
A 4 3/4'' length of CPVC
So, start with these two guns. The underrated DTB and the great NF. (I am aware of the non-stock NF)
I can't go into great detail on how to cpvc-coupler the NF, but cut the coupler in half. Glue / Epoxy the coupler onto the second internal piece that's after the plunger tube. Basically it looks like this.
Minimize the shell using this cutting bit for your dremel.
Take the DTB, remove the air restrictors and cut the posts off the piece that looks like the NF's air restrictor post thing. Wow that was indescriptive, I'm sorry.
Take your ordinary T-Coupler
Take the 4 3/4'' length of CPVC and cut it about 1/2'' in. Like so.
Take the rod from the DTB cocking handle. Get a drill bit the same width or a bit bigger, drill where marked.
