A new hop-up packing will allow more accurate hop-up adjustments. AIMTOP enhanced type packing is designed to match high power upgrades at 400fps plus . High power upgrades require a harder hop-up packing since softer material may deform from the higher power. However if your gun shoots bellow 400fps, then stay with AimTop original (black one) since otherwise this hard type will not grip the BB properly on low power configurations. Especially recommended to use this hard type hop-up packing onto upgraded sniper rifle as well for improving semi mode shooting effectively.
