Frequently asked questions about GBB hop-up chambers & buckings

Are all GBB buckings and chambers compatible?

No, compatibility varies by brand and platform. Always check whether your chamber is suitable for Tokyo Marui, WE or another brand.

What hardness of bucking do I need?

Soft buckings (50°-60°) are ideal for lower FPS and provide extra grip, while harder buckings (70°+) perform better at higher Joule settings and with heavier BBs.

Should I get a CNC hop-up chamber?

This is not a must for standard builds, but CNC chambers offer much finer adjustment and long-term stability – especially interesting for high-performance setups.

How often should I replace my bucking?

With regular use or intensive skirmishes, it is wise to replace your bucking at least 1-2 times a year to maintain the best performance.

Combine your GBB hop-up upgrade with an Inner Barrel for maximum precision or choose Airsoft BBs in various weights to make optimal use of your bucking. Want to make your setup even more consistent? Then take a look at our Gas & CO2 bottles and capsules or complete GBB Parts.
