Got bored and after seeing the internals of a redux I decided internal air lines would be a slick looking mod.
Had this up on MCB for a while and thought I'd share to those of you who don't head over there to often.
Milled a hole in the bottom of my 86* frame and tapped the top of the ASA for a microline fitting.
Milled another hole for the microline to travel to the new port in the valve.
Milled the last hole in the trigger frame to allow an area for the top microline fitting to sit.
Finally tapped the valve in the bottom for the new air line
I also bobbed the valve to remove the old NPT fitting hole and for a slightly sleeker look.
If the gripframe is milled correctly you can rotate the ASA backwards for Hawaiian style, or normal for using a tank like so:
I did it with a Garg trigger assembly and CCM 86* frame, but other people have successfully done this mod on stock CCI assemblies w/ CCI 45 frames. Your mileage may vary.
