Aim Top hop-up rubber will allow more accurate hoop-up adjustment. AIM TOP enhanced type hop-up rubber is designed to match high power upgrades at 400fps+.
High power upgrades require a harder hop-up rubber since softer material may deform from the higher power.
However, if your gun shoots below 400fps, then stay with AIM TOP Original Typ hop-up rubber ( blue or white) since otherwise, this hard type will not grip the BB properly on low power configurations.
Especially recommend using this hard type hop-up rubber onto upgrade sniper rifle as well as improving semi mode shooting effectively.
Dedicated to springs with power M150-190 / 495-630fps
The set contains two hop-up rubbers and two spacers.
