They don't make lighter recoil springs. From what i've heard HFC is similar to TM M9s, so you could try getting a stock TM recoil spring. However it might not be strong enough to move the weight of the metal HFC slide. The HFC is pretty tough, you shouldn't have any issues with the slide cracking with regular propane usage, just keep the GBB oiled regularly. And there is no airsoft C7s or C8s. If you want a GBB C7 or C8 rifle you should try looking for a Sun Project M4 gas rifle and do some modification work on it.
