So, In the last month I have had 3 customers with the same issue with all of their guns and I am seeing a pattern.... They were all APS, all EBB and they all have electrical contacts that get carbon build-up very quickly causing the gun to have no electrical flow at all. So i cleaned the contacts and re-adjusted them so they make better contact
The weird thing is all the guns are virtually new (about a month/ only gamed 2-3 times), and they are all APS.
The 2 i have already fixed have been running well and the customers say they have been running great. But this keeps becoming a reacquiring problem with these APS gun users and i was wondering if it was a APS quality control issue or is this just common with EBB guns?

Im puzzled, I'm not sure if its a quality control issue, or the contacts build carbon quicker due to the extra load in the middle of the cycle (blow back)???

O and i forgot, 2 of the guns were ebb m4's and the other was a ak-74 ebb
