I have the V2 bolt, I opted to use the custom steel one I got already since it was CNC'd not cast
They should both hold up though.
The mags themselves do not fit, however, the part that holds the BBs fits perfectly in my Pioneer Kar98k clip pouches if that matters lol... Considering each CO2 charge can shoot approximately 40-50 shots, it's not too bad if you mind slightly slower reloading times, but not too bad.
