Hmm.. tricky. Basically, the hopper goes into a transparent tube which bolts onto your gun. This tube is made of really brittle plastic (check out a pic) and has 2 bolts, top and bottom. I managed to overtighten mine and the damn thing broke!
Typical eh!?
Well I called PlanetEclipse (I'm from the UK) and got a replacement in the form of a tigher neck tube that just squeezes over the feeder tube and the revo... Much better!
The Revo is needed as it's cheap, not too fast and the marker is really pretty fast and needs its regular meals !
OH MY! I just remembered the most important thing! When you get your marker, unscrew the trigger unit using the 2 hex bolts and loosed the small screw in the recess on the trigger.
You can't see it or adjust it from the outside.
Test it for a few clicks, but you can make that trigger gap free, so it'll rip at the slightest movement! If you have any probs wirth this try me at

Always happy to help!
