For one, I own a DE UMG M89. This is the hop-up system that is installed when you buy the gun from anywhere. After a month's use, I discovered that my pellets were dropping constantly, and adjusting the hop-up had no effect. I take it apart to discover the plastic barrel snap broken (in half), and the adjuster is disabled [broken]. The spacer basically was completely inside the chamber and wasn't even moving... Also the bucking that is already installed in this may wear down after a few months use so be prepared to buy a new hop-up and new bucking w/spacer. (G&G Hop-Up & G&G bucking highly recommended). You can sometimes fix the bucking problem by greasing it up and using lubricant. I suggest replacing the whole system right after or as you buy this gun for maximum performance.

Hey its the hop-up. Not too much else to say. My old one broke when I was messing around with it trying to upgrade it a little.
Its the hop-up I ordered... exactly what I expected.
