My XS B7 is shooting weak and I think it's a combination of a spent mainspring and worn leather seal. Trying to find a decent replacement spring, I have an Industry B3 spring from Archer but was thinking of getting one of the Titan springs they sell for the SMK rifles. Anyone know the best bet to get something that will be similar to the original Xisco spring (35 coil .120 wire .482 ID)

Found Vortek has one that should fit nicely, may get their leather replacement seal kit also
