Got this as a kit. Packaging Accidents happened, but FF team responded fast. Manage to complete the build with spares from last build anyway, using prok26, .509 anodized 16” barrel, purple worker g3, got max 305fps. Stabilized at 240-270fps after a few shots.
Only complain is top rail section and rear pistol grip needs o-ringed for a snug fit. Other than that, am satisfied

Mine is amazing. I got a pre-built. It came to me and it fired perfectly. so just an amazing blaster.

4.5 stars. Blaster arrived good, wait wasn’t too long. The orange tip arrived cracked, but they quickly sent out a replacement. Print quality could be slightly better but that’s my only gripe. Happy with my purchase.

It’s very strong, nice. I’m happy and looking forward to getting the Woozi! The Caliburn is powerful and sleek, my wife is all like, “that doesn’t look like a toy!” Hahahaha. 😊
