So, if a G&P SPR with a 150SP spring and 9.6V 3300mAh battery, that is prone to seizing up in the way you describe, and the trigger is pulled full back each & every time, how is it that it still seizes every couple dozen shots?
I've worked on one, was told by the owner that the problem is only pulling the trigger halfway at times, and/or til it fires, then releasing it. My answer was to pull it every time full through. Yet after I fixed a bad install of a Carrot grip, I was putting it through it's paces and found that even when pulling full clean trigger pulls all the way back, it'd still lock up once in a while and have to go to a full burst to fix it. Is it still normal for a mechbox to lock up when shot properly? My MP5 never locks up when fired repeatedly on semi, nor have I experieced any others doing that until the SPR came around.
