Air rifle porting! will it gain FPS?
in this video I tried an idea I came up with late one night and wanted to test it out. with a background in modifying and tuning everything (Brotuned) I can't leave stuff alone or stock for long, i was brainstorming on how to get more performance out of my 495 fps air rifle. with engines if you open the ports you allow greater volumes of air/exhaust in and out of the engine. An air rifle is basically a spring actuated air pump. so why not open up the port from the compression chamber to the barrel. this port was very small upon examination.
I then disassembled the rifle and examined its internals. I wanted to check on a mod I did about 10 years ago also DIY jb weld piston mod. which to no surprise is holding up perfectly. sit back and enjoy the pursuit of fps.
