hi,
I'm new owner of a nice KJW M4 A1, and I'm wondering if there is a
special maintenance guide available somehere here, like I found for my WeM4CQBR (really nice cleaning guide made by a member here).
Just want to know which are the critical parts to dismount, clean and lubricate, and wich lubricant to use on specific parts, for a continous trouble free operation.

thanks!
