For: G&G UMG Metal Hop Up
This is a full metal UMG hop-up. Compatible with TSD, Double Eagle, and obviously the gun it was made for, G&G. This is very well built, and so is the plastic the plastic barrel fastener, which is a high quality ABS plastic. (Not the cheap kind). Double Eagle makes an imitation of this - which I already have a review on. Overall the performance of this hop-up is exceptional in my UMG so far. No jams or feed issues whatsoever, and raises distance overall. The adjuster is an ABS plastic slide, no gears. Also installation is a breeze if you know your stuff. fits very well into the gun. However, in TSD and DE UMG's, use caution when inserting the magazine, because if you shove it in there harshly it might not connect to the hop-up feed properly and hit the metal part, wearing it down quicker.
Sturdy metal frame
Good barrel fastener
Overall high quality
(Not many cons to think of...)
