I dont know if this is in the right place, so mod's feel free to move it. Anyways, I don't know how to clean and re-lube my Double Eagle UMP M89's gearbox, and I hear they come with crappy industrial grease in them, so I wanted some help, or someone of knowledge to grease my gun. The grease and other materials are needed. if anyone wants to or will do this for me plz PM me with a price!
I live in Oro Valley near 1st and oracle.
UPDATE: I personally installed the hop-up bucking, I just dont have the lubricants to re-lube the gearbox, its a standard V3 gearbox. so all thats needed is someone with a knowledge of V.3 gearboxes and the time/patience to clean and re-lube the gun for me. Will pay for the work, PM me with an estimate!
