ROF HPA Gun

The ROF HPA Gun is the easiest way to get the complete MechLabs system. We started from the polymer body of the Poseidon Theseus, then replaced all the internals with our own. Everything inside was installed by us: the XX-Mod engine, the ROTO hop-up chamber, the ZERO Cap Alignment and the Step Nozzle 67. No parts to source, no install to plan, no workshop time.

Everything comes installed and configured. That means it is a true play out of the box HPA gun. Connect your air, load a magazine and go. You do not need to learn how to fit an engine or align a hop-up before your first game.

Why this setup? Because these parts were made to work together. The XX-Mod is our fully mechanical HPA engine: no battery, no solenoid, no wiring. The ZERO Cap Alignment joins the engine and the ROTO hop-up into one unit, so the nozzle is always perfectly aligned and the receiver tolerances no longer affect your shots. The Step Nozzle 67 then improves BB positioning and the seal inside the ROTO. The result is a replica that shoots consistently from day one.

The result is a very solid and ultralightweight HPA gun: only 1.5 kg in total. It shoots through a 245 mm inner barrel. You feel the low weight after a full day on the field, when your arms are still fresh and the gun is still easy to move with.

And the price makes the decision simple. If you were planning to buy the full system anyway, the ROF HPA Gun costs only a few euros more than the XX-Mod, ROTO, ZERO Cap Alignment and Step Nozzle 67 bought separately. For that small difference you get the complete body as well, already built and tested. It is the best deal in our range if you want the full MechLabs experience.

Important Note: always check your power with a chronograph before playing, and follow the power limits of your field.

How to Use

The ROF HPA Gun arrives ready to play, so getting started is quick. Connect your HPA air source and set your regulator to the pressure you use for your field. Load a magazine and fire a few shots to settle the system. Then chrono the gun before your first game, because every field has its own power limit. Finally, adjust the ROTO hop-up for the BB weight you are using. Once that is set, you are ready to play.
