VFC Scar-H problems.

AnthB · September 22nd, 2013, 15:34

Was shooting 330 fps (.25s) before bringing it in for upgrades ( maybe a month old and I only play once every 2 weeks. I'm a semi-auto type of guy )

Has an m120 spring new piston and longer barrel and I bought a 11.1v 1000mah Lipo.

Burns up a battery with-in 5-600 shots, something like 360-370 fps with .25s.

Not exactly ideal. Could anyone give some ideas on what could be the problem? I bought it in for upgrades but it couldnt reach what I wanted (400+ fps w/ .25s). Im sure some of you read my previous thread on this but its probably better that I put it here anyways.

Is it an M120 or an M130 spring?
400+fps with 0.25 ~ 447fps with 0.2g. You're not going to hit that with either spring. 360-370 with 0.25 is about right for an M120 spring.

Since you have poor fps and poor efficiency, your issues could vary wildly: anything from poor shimming, poor wire quality, poor electrical connections, poor choice of motor, low-quality battery, poor air seal on the piston head/cylinder head/nozzle/hop-up rubber/hop-up unit, improper selection of cylinder size.

A SCAR-specific observation is that the SCAR-H has a retardedly long nozzle which is proprietary, and last time I checked it didn't have an o-ring on it so that might be an air seal problem. Also, with a long nozzle you may run into air seal issues with fully-loaded mags causing ammo to push upwards on the nozzle, creating an air leak.

Contact myself or a reputable airsoft gunsmith to fix your gun.

I wanted a m130 spring but it got brought down to a m120. That fps also was before the upgrades. My spring was compressed for too long or something like that.

Quite possibly a very poor shim job. I've seen a gun that required too much torque to cycle, but once I reshimmed it because the previous "gun doc" couldn't shim for shit, noise levels went way down, rate of fire doubled and the battery ran for much longer.
