"Bought a URX Raptor a couple years ago and it has this hop up in it. Still using the stock hop up unit after more than $700 of upgrades to the gun. This hop up unit is a incredible hop up for a stock unit. To this day I still look for better parts to put in my Raptor. The hop up unit and 6.03mm Stainless steel stock inner barrel are the 2 things I have not changed from stock parts because their performance is flawless. I have seen the adjustment wheel come loose on one of these units before, all I had to do was put a washer under the screw that holds the wheel on. This was on a friends APS Kompetitor m4 and it still functions perfectly.

- One Piece (Has PERFECT air seal)
- All Metal (Durable will not warp bend or crack if you drop your gun)
- Maintenance friendly (Simple to: take a part and clean/ install custom nubs and flat hop, R-hop, etc...)

- Can't give it 6 stars

Please don't read the negative reviews and confuse product quality with human error.

"This hop-up is nicer than I thought it would be.
It was pre-assembled when it arrived, and fits my m4 nicely.

Easy to install

The skinny spring on mine bent (but it was probably my fault)
The gear that you use to adjust is a bit hard to turn, but there's probably
a way to fix that.

Overall, it is a simple metal hop-up that does its job.

"I did not buy this, but it came pre installed on my zombie killer m4.
After only a couple matches my aim was horrible and after I got home and checked out the hopup, I found out that the gear got completly stripped and therefore useless for retaining any kind of adjustment.
yes all metal but the gears they used for this are super cheap crayon level plastic.
