Charging the cylinder and filling the magazine
Charging the 50cc cylinder is made super easy, because Reximex utilises the probe stick. One end inserts into the gun’s inlet, just forward of the trigger, and the other snaps straight into a Foster connector. This means for anyone with the standard Foster airline fitting already in use, no other threads and components are needed. It’s the way to go, and well done Reximex!
Reximex specifies a maximum fill pressure of 250bar for this model, and it’s stamped on the action too, so I stuck to that for my test – insert the adaptor, fill, bleed and remove adaptor/airline. No dust cover is included for the valve, which is silly given how PCPs hate dirt, but a minor detail in the big scheme of things, and annoyingly a regular omission! A manometer is recessed into the front of the cylinder, and it’s nice and clear to read – green working zone and red danger zone – which is probably the most logical design. Let the needle drop to the lowest part of the green and you know it’s time for a refill.
Users can opt to utilise a single-shot tray or use the magazine, which is as it should be. I opted for the magazine for testing purposes, and the Reximex design certainly looks stylish with that yellow internal drum. These magazines are nine-shot in .177 (tested), and seven-shot in .22 calibre. Filling is pretty simple – just twist the cover anti-clockwise, then drop the first pellet into the first hole, twist and repeat until full. One mag on test was very tight to rotate but the other worked perfectly.
Sighting options: open sights, MOS plate and scope
The fibre-optic open sights fitted here are excellent, with the green dots of the rearsight combining perfectly with the red foresight element. The rearsight is adjustable for windage only, incidentally, via a small screwdriver, but with a super-long sight line afforded by the long body profile, the Mito Race is off to an impressive start.

As mentioned earlier, this pistol comes supplied with an MOS plate, and for those unfamiliar with the term (that included me before this test), it stands for Modular Optics System. The small plate is designed to fix to the rail, and it can then accept various red-dot sights and the like. That’s attention to detail from Reximex for sure, and a measure of its thorough approach these days.
I’d already decided that this model deserved to be pushed, so I dug out my trusty 2x pistol scope, and since that only uses one ring mount, it easily bolted into place using the 11mm dovetail rails up top. OK, 2x magnification is super low, but it’s so user-friendly that it gives a good idea of any pistol’s potential.
Handling, side-lever and trigger
And so to the business end of this report. We referred to the new side-lever being larger on this version, and it works really well, being comfortable, easy and smooth to operate. With the lever withdrawn, a full magazine can be slid in using the guide groove from the right side. Incidentally, the same magazine that proved tight to fill was also an irritatingly snug fit in the breech. The other magazine, however, worked perfectly throughout; so if this were my gun, I would just get the other swapped out as a suspect item.
With the mag in position, close the lever, and we’re good to go for nine shots, just as fast as we can cycle the lever. That’s pretty fast and smooth since you asked, but of course, that’s hardly the point here. This pistol deserves methodical, deliberate aiming to make the most of the obvious potential on offer.

The revised trigger looks the part, with that ventilated blade, and my test gun came perfectly set too – with just a small amount of movement on the first stage, then a little creep and a gentle release for the second stage. I favour a short first stage, so this worked well. That tasty Turkish walnut grip is technically ambidextrous, but despite being, in theory, all things to all people, the fact that a palm swell features on both sides and a shelf sits at the base means the hand is cosseted and supported perfectly. Handling, therefore, is hard to fault.
How does the Mito Race perform on test?
And so to those all-important performance figures. The Mito Race feels very crisp to shoot, and while it is fairly noisy, the air delivery feels quick and efficient, with no rasp to speak of.
From that 250bar fill, this regulated Mito Race recorded 117 shots, before residual pressure dropped to 80bar. I reckoned this must be near to the reg pressure, so called it a day. 5.5 ft/lb is pokey, given the air pistol power limit, and with a total spread of 40fps – not amazing consistency, I grant you – this is still a very usable tool. Like many regulated airguns, though, velocity started a bit lower and gently climbed before dropping, so charging to a slightly lower pressure is well worth experimentation and will increase consistency.
That said, accuracy was quite simply superb on test: a literal ragged hole at 10 yards was a great start, but over 20 yards, the hole only grew to a quarter inch, using quality Air Arms Diabolo Field ammo, admittedly. Basically, I can see why the Mito has been such a hit for Reximex, and with such a blisteringly accurate action, it’s a shame that the shoulder stock available with the synthetic-stocked versions doesn’t appear to be an option with the walnut. Looking closer, the synthetic grips have moulded recesses for the stock’s protrusions to snap into. Never mind – it’s a customisation project and many enthusiasts will consider it well worthwhile, I’m sure.

- Clear, recessed manometer
- Excellent fibre-optic open sights and a long sight line
- MOS plate supplied for red-dot sights
- Smooth, larger side-lever and a well-set trigger
- Supportive Turkish walnut grip
- 117 shots from a fill and quarter-inch groups at 20 yards on test
Weaknesses
- No dust cover for the fill valve

Verdict on the Reximex Mito Race
As it stands, the Reximex Mito Race is a classy piece of kit. Smooth and easy to operate, and deadly effective. That shoulder stock omission apart, this new Mito Race is a pleasing evolution of a classy target pistol. No longer a cheap option, but operation and performance are hard to fault.
