Looking for a great Hopup Unit for your AEG or PolarStar PR-15? You have just found one of the best on the market. 

All of us here at Amped Airsoft either use the Prometheus Perfect Chamber or the Systema Hop Chamber in all of our personal replicas.  This unit is by far hands down one of the best out there when it comes to performance and quality.

This hopup comes with the strike chamber which allows you to adjust your hopup to a finer degree.  It also holds it's position once it is set. 

Please note that you will need to provide 2 of the 3 hop gears from your previous hop unit.  This produce only comes with the Orange Hop Components and Chamber pictured above.
