“This thing is amazing for the price, sure its not full metal like other hop units but it sure does perform like them! Just goes to show you don't need a fancy name and material list to perform the best.”

“This is a great hop! Solid, Durable polymer. Has a ratchet system to LOCK your hop settings in with very fine adjustments. I have this and a Maxx hop and I prefer this. I put O-rings on the front and 1 on the back and the air seal on this hop is perfect and will hold for hours.”

“I ran this unit for an event with a 6.03 Action Army barrel and maple leaf bucking and it worked flawlessly. Really like how it has numbers integrated into the rotary and allows for a specific power in hop regardless of bb weight.”

“I paired this with a Prometheus 6.03 barrel and purple bucking in a PolarStar Jack build. I love the small increments the hopup dial has to you can get really dialed in.”
