Airsmithing Part 3

The adventure continues. So we got the mp5k fully functional again. It's not that impressive of an fps increase with the sp120 spring but that is just because of its short barrel length. If CQB City allows its use indoors with an extended barrel then I will throw one in and see a better fps increase. Its currently shooting at 250-260 fps which is still better than the stock 230.

The m15a4 is fully functional now. Chronos in at 365 with the m120 spring. We happen to have another m15a4 that is not functioning with an upgraded cylinder and piston head so I'm going to throw those parts into mine and see if I can get some more power out of that m120 spring.
