King Arms M4 Spring replacment.
Down grading my spring to an M110 so I can play on fields and get a better ROF.
Does anyone how ever have a good VIDEO on how to go about taking the gun apart and getting to the gear box?
Searched here and youtube and no specific videos for my certain gun.
And I would like to do this myself rather then going to a gun doc, I have all the tools needed to to do it just not the know how.
