I currently own the recoil cqc scar l. this is the second one that I have owned but I have a problem after two uses the gears have gone and this issue happened on my first one aswell. I absolutely love the weapon but it is totally unuseable due to the gears and the fact its electronically dead is this a common fault or have I just been unlucky with this particular model I will be up grading it but need to know if it will be worth it in the long run
