Upgrade your rifle's standard factory hop-up with this Improved Hop-Up Bucking. Designed for spring mechanisms of SP130-150.

Why choose this hop-up bucking?

• Hop-up bucking increases friction on BBs for improved ballistic trajectory
• Hardness of 70° for long-lasting toughness
• Twin-ribbed body prevents sliding and maximized air seal
• Suitable for all AEG models

Why not?

• Harder-degree bucking may tend to over-hop ammo

Pro Tip:
A hop-up is a device installed in airguns to increase the range of a pellet or BB. This system puts a back-spin on the ammo as it passes through the barrel, causing the projectile to fall less over a given distance than it would under normal conditions. Most hop-ups are adjustable to account for the weight of ammo and a player's preferences.
