For: Magic Box Miracle TOT Inner Barrel BAR10 & VSR10 & AK (433mm)Product Information:
Went to the AirsoftGi store to pick it up for my KWA SR10. Brought it back home, installed it and it works better than the stock sr10 barrel. It increased my range about 30-40 feet. The accuracy stayed the same. Everything in my sr10 is stock and i can hit a 6 inch sign from 240ft away 2/6 times with .25s.
not sure about fps
accuarcy increased a tiny bit
overall i would reccomend this for any gun
may stick out of the flash hider on the sr10, but its un noticeable.
