Motor straining while firing
I have this exact rifle. It has the blow back feel to it as well.
Lately while trying to fire it, it sounds as if the motor is straining, it fires intermittently and freezes. The batteries are fine and i have occasionally put a drop of silicone lube on a few BB's.
Before i use the guide to take it apart, i would like to know if there is anything specific i need to be aware of or if there are any known issues with the rifle which could be causing this.
