"I just recieved this hop up chamer and my g*d, the feel and look of it is 100%.
When i recieved it i got all the parts needed to assemble it, even though its spesificly written that theese do not come with it, just the hop up unit itself. Assembly is straight forward and took no more than a coupple of minutes at most.

When i fire the gun however it doubble feeds on every other shot i take, but this i think is the air nozzle and not the hop up unit itself, so ill order up a new nozzle and test it out.

Pro's:

CNC - built like a tank
Great looking, nice colour that adds a bit of bling
Came with all the part to assemble it (O-ring, wheel, you name it)

Con's:

None that i can see right away exept for the gun doubble feeds (but i dont think the unit is responsible for this)


all in all i would say this is a pretty nice hop up chamber and would recomend it to others to buy

"I have already reviewed this, but I wanted to add that it works with a Maple leaf 75 degree bucking, nub and an angel customs 6.01 barrel.

I also recommend 5.98 max precision BB's at .25 grams

"Comment on review above, then review
- Feeding issues other than no feeding at all are caused by the bucking characteristics, air nozzle, and tappet plate. Not the hop up unit.

Pros Works great, and retains setting
Cons the adjustment screw for the hop up unit retention is finicky

-For use in ICS guns you need to shim the unit forward with a neoprene washer then you can replace the nozzle with a TM spec air nozzle.
--additional note, I use G&P magazines that required a 1/16 washer to feed well.
