link to gearbox ???
Thought G&P weren't exactly $hit hot internally
Lonex boxes seem to be built more precise but not cheap - think they use 16:1 gearing
SRC guns "can" be a bit qwirky - but tbh that could be said for a lot of so-called TM compatible badge
SRC gearboxes come in 3 gen's or types - you could have a cheapo 1st gen with 6mm plastic bushings
or a 3rd gen with 8mm metal bushings/bearings in
I personally buy say a £50-£60 box to see if that works better if fully 101% compatible
then strip and service your old SRC box - normally the box that came with your gun if ok is the one that should work best or best fit/operation
nozzle lengths, box shell thickness even, everything all perfectly lining up 101% is stuff we all take for granted
but numerous factors and different boxes can be a nightmare or headache to sort if there are differences between two gearboxes
A lonex box is reported to be a very good sound box for people seeking a great drop in replacement but not cheap - over £100 - £135
(dunno if I'd ever pay that much myself)
could get a £50 one from Hong Kong but they might come with a high spring
could get a quick change spring gearbox but some of these use micro switches and can burn out trigger contacts on higher batteries
it will be ok for a while on 7.4v or 8.4v but no more tbh
whilst that is in your gun you can look at servicing your old box
Or - maybe just send it to a tech coz so called "upgrading" is not as easy as we all think and often make an ok gearbox worse if you don't take great care
£100 is nothing in upgrade terms - a £50 box with £50 upgrade parts is really only as good as how they were fitted and only as reliable as the weakest component inside
