A few questions on King Arms m4a1
 

I have a few question about the King arms m4a1 :rolleyes:

What will be the first upgrades needed to make it ''Last Longer''?
Any tips about opening, Putting grease on it and how to shim the gears?
Is $265 a good deal?

Thank you for all your help, Aldo 69

Want it to last long? Leave it as it is. Unless it comes with an overpowered spring, then you would have to oppen it to replace it.

alright, I'm changing it to a m100

Once thats done it should last you years and years.

Grease with proper grease if it comes out of the factory with "cakey" white lithium.

I personally like the Modify PTFE grease or Echo1 grease set (gear, airseal and bearing all in one pack) if you want to go with an "airsoft" grease but go with whatever is available, there really isn't too much difference between the different brands. Also, gear grease for bikes is a trick that I use as well (love that FinishLine Teflon "Dry" Lube or Ceramic Wax lube).
