Very nice...I find it funny/ironic that the pop-off valve acts as an anti-safety in the configuration it is used in :lol: .

Increase the barrel :D Longer barrel (provided you have the power which im sure you do) is more accurate. How does the modified pop off work?

This is what I did to the pop off valve. First I drill out the hole thats on the side..I think its to keep the cap from being unscrewed.. Second I made a special tool so I can unscrew the cap.The rod thats inside this valve I threaded,but the one thats on my gun now is not. I just pinned on a bolt coupler to the rod and screwed on a hook bolt for the trigger. The spring in this photo is the original, but the one thats on my gun is way stiffer..I think you can get adjustiable pop off valves. They come with different springs..The tool is just a 3/8" or a 5/8" wood drill bit...I heated it up to get rid of the hardness of the steel so I can cut it..I cut a slot in the center so I can unscrew the cap around the rod..I hope Im explaining it correctly..Its kinda hard to explain things in writing. I think I can explain it better verblely..Also I am almost asleep..Its 2:00am here. As for making the barrel longer, I would ,but the brass pipe I got is kinda pricey$$$ Im going to trash the laser sight its garbage. I think Im going to make peep sights. I would think that would be good enough for sighting in. I'll post new pix of it when its done. :salute:

Right now Im expermenting with a breech loader..It came to me in a dream..I think It will work? I will post pix soon. I think it will be a easyer way to reload. : The only draw back it adds an extra 1 or 2 inches to the gun. :idea:

nivekatoz, firstly very nice gun, clean and functional, If you add a spring to the other side of the pop off to increase the pressure at which the valve pops, you might be able to increase the power slightly, a catch might also work, a sort of trigger assembly, also last idea is if you reduce barrel diameter and connect it to a continuous airsource you might just have a auto on your hands..
