Prometheus - Air Seal Hop-Up Rubber - Hard Type

If the hop-up adjustments have no particular effect on the BBs, it may be that the hop-up rubber is worn or wrong in relation to the rifle. 

This rubber from Prometheus is a hard type that is well suited for rifles that shoot 400fps or more. Harder hop-up rubber ensures that the bullet grips the rubber well even at high speed. 

If the rifle shoots below 400fps, we recommend a softer hop-up. 

We recommend this rubber especially for sniper rifles and to improve your semi-auto accuracy!
