ok I will try that tomorrow. I had JUST charged the red battery, but it could be weak or crapped out.
I should just be able to turn the sear arm out to extend it right? trouble is there is only a credit card thickness between the sear arm and the trigger now, which is what is supposed to be. My silver one travels only half the distance of the red one before it fires in mech mode.
also, if I put my 2K9 body on the red lowers, it fires fine. which means i know the battery at least works and the sear arm length should be fine. It just won't fire with the red body on the red lowers.
I will also swap the silver body on the red lowers and try that too. Thanks.
