Huben Huben GK1. My first PCP pistol

[airgunmike56]

I got a GKi I tuned down to 500 FPS, I get a little over 3 mags on a 4500 PSI fill and do not need a moderator , This rattler I took out was at 880 FPS with a 18.1 gr JTS 22 caliber, Little over kill for one foot shooting , Much happier with it tuned down,

Peskadot do you have access to a 3d printer? I have a stl for a smaller moderator. that works great. even works on my GK1 .25 shorty.
