A there any limitations for upgrading the ics sig 551
It uses a standard V3 IIRC so no.
If i remember correctly the sigs use version 3 gearboxes. If thats the case then there are tons of upgrade potential as v3 gearboxes are almost as popular as v2s.
One note I have to mention is that it has a medium motor, not too much of a limitation but a little harder to find, and resale value for mediums isn't that great.
