Lubrication tip for M4 GBBR's??
I just acquired a M4 GBBR and I'd like to learn how I keep the gun in good shape? I know how to care the GBB pistol but GBB rifle is my first time.
I've already tried to find a source or video on the internet but all I found was for real AR-15...
So if you know how please let me know where to spray the silicon oil and where to apply the grease. I want to keep my GBBR for a long time.
Thanks for your time.
