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!
