First Strike FSC w/ T8.1 barrel and magazine
31.5 Joules. 12g co2 in the T8.1 magazine. Stock T8.1 barrel.
Milsig oring won’t increase the power but it won’t break as easily at high power.
Grimburg HP68 T9.1 over 400 FPS shoots thru Pig Skin
Felix shoots thru pig skin with almost 60 joules, using his T9.1 on co2. The only customization… Milsig firing bolt oring!
