"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.

"This is a great hop up chamber! I installed it in my Polarstar and it feeds flawlessly. It's got a very precise adjustment so I can get the perfect amount of hop for my BB's and it also looks awesome when I pull back the charging handle. All in all I think this chamber is well worth the money I paid!
