ROF + FloMax TS HPA Gun

The ROF HPA Gun with FLO MAX TS and Stock is the complete MechLabs package in one box. It is our ROF HPA Gun, fully built and configured, plus everything you need to carry your air inside the stock: the FLO MAX TS regulator with ON/OFF and the Tank Stock Cover for 10ci and 13ci HPA tanks. No remote line, no tank on your vest, nothing to catch on branches.

The gun

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.

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 gun itself is very solid and ultralightweight: only 1.5 kg. It shoots through a 245 mm inner barrel.

FLO MAX TS regulator with ON/OFF

The FLO MAX TS is the tank stock version of our FLO MAX regulator. "TS" stands for tank stock: it replaces the standard M4 stock connection and feeds the engine from a tank sitting inside the stock. It is CNC machined from aluminum and gives you an adjustable output of 135 to 140 PSI as standard, set with a hex key.

The ON/OFF module is the part you will use every game. Press the button to pressurize or depressurize the regulator. You do not need to unscrew the tank, so you do not stress the threads. It is also a safety feature: turn the air off when you are in the safe zone, during handling or before maintenance, and the gun cannot fire.

Tank Stock Cover for 10ci and 13ci tanks

The Tank Stock Cover turns your HPA tank into the stock of the gun. It fits 10ci and 13ci HPA tanks. The body is light polymer with weight reducing cutouts, with a rubber butt pad for a stable shoulder contact. An aluminum clamp handle locks the tank in place, so it does not move when you aim or run.

Why the bundle

If you want the full MechLabs setup with internal air, this is the simplest way to get it. Everything is chosen to work together, the gun is already built and tested, and you only need to add your tank.

Important Note: the HPA tank is not included. Always check your power with a chronograph before playing, and follow the power limits of your field. Never fill or remove a tank above the pressure it is rated for.

How to Use

Start with the ON/OFF in the off position. Screw your 10ci or 13ci HPA tank into the FLO MAX TS, place it inside the Tank Stock Cover and close the clamp handle until the tank cannot move. Check the clamp again after your first few minutes of play, because it can settle. Turn the air on with the ON/OFF button, load a magazine and fire a few shots to settle the system. Then chrono the gun before your first game, since every field has its own power limit. Finally, adjust the ROTO hop-up for the BB weight you are using. When you leave the field, turn the air off before you do anything else.
