New site looks great! Come a long ways since the SpudTech era!!

At any rate, playing around with a piston build for the first time in a decade. I've used the basic air compressor blow gun plenty of times in the past, but they just feel like they are made of $1 worth of chinese steel (odd, right?). I accept that a valve will never feel as nice as a sear based system, but hopefully there's something a little more precision? Doesn't need to be very big... GGDT is still showing plenty of flow with a 0.15" dia exhaust. (the design has an assist piston, so I only need to introduce a 15psi pressure difference between chamber and pilot, and the main exhaust will dump out the side).

If the options are all rather expensive, I will just stick to the blowgun for this test bed.

lift off valve, sear release:)

Trigger feel as you design the trigger-sear geometry

Also saves on a blow gun ( I am extremely cheap)
