"Just bought this gearbox because my stock classic army one broke. This is a great gearbox, except it has a plastic spring guide and when i received it the fuse box was broken. Overall this is a good replacement gearbox, but not really a upgrade. 4.5

"ordered this 1/22/14 and received it 1/27/14 so the time for delivery wasn't bad. however upon receiving package i knew immediately something was gonna be broken without opening it up. the gearbox came in a 12x9.5 flat rate "ENVELOPE" let me repeat that...ENVELOPE. not a cardboard box with packing peanuts, bubble wrap, even rolled up paper would have done, but was put in an envelope. im not a airsoft technician but i know the gearbox is the most important part of the gun any gun. not to mention its the most expensive part. i wish a little bit more common sense was made on someones part when they decided "hmmmm envelope or cardboard box with packing hmmmm"??? i just called them and and they are starting my return. gave 2stars because it came in 5 days.
so this review to be continued.
