yes... lube is good for your gun.
would real gun lube work?
DO NOT USE ANY REAL STEAL LUBE! Unless you know for certain that it's petroleum free and/or will not harm rubber & plastic. I'd stick to 100% silicone spray or gel to lube your GBB.
the whole interior is metal except for the hop, and i aint lubin the hop...but ur right...I'll just use that silicon spray
get some oil or grease if you can. it works real goot.
