Umarex Komplete PCP Conversion From Air Venturi
Since the beginning, people have been asking for a Umarex Komplete PCP air rifle conversion system. And now one is available Air Venturi.
How does it perform? Let’s take a look…
Umarex Komplete PCP Conversion From Air Venturi – Overview
As we can see, the Air Venturi PCP Conversion for Umarex Komplete comprises a black, anodized High Pressure Air tube. It’s around twice as long as one of the original NitroAir cartridges and about 3 Oz heavier. The scoped gun used in these tests weighed-in at 7 Lbs 11 oz.
The PCP conversion uses an identical screw mounting thread to that of the NitroAir cartridges. It screw directly into the Komplete.
At the other end is a standard 1/8-Inch NPT “Foster” male quick disconnect. There’s a substantial cover that screws into place to protect the connector when not being charged with High Pressure Air. Very good!
Operation is extremely simple. Screw the Air Venturi Conversion onto the Komplete, remember to shut the de-gassing screw, connect your HPA supply. Disconnect and shoot!
Well it’s nearly as easy as that but for one thing. The Umarex Komplete does not have a pressure gauge. Neither does the Air Venturi Conversion. So it’s essential that you use the gauge fitted to your HPA tank, pump or compressor so as not to overfill the gun.
For simplicity and safety, I set the automatic pressure cutoff on a portable compressor to 3,600 PSI and filled that way.
Umarex Komplete PCP Conversion From Air Venturi – Performance
To test the Air Venturi PCP conversion, I used the same Komplete as I have for previous tests. That way we have an “apples to apples” comparison.
It’s in .177 caliber and here’s how it performed when shooting one full NitroAir cartridge in our comprehensive Hard Air Magazine test report.
As you can see from the graph above, the Umarex Komplete delivered 60 consistent shots from the NitroAir cartridge.
To test the Komplete PCP conversion, I used an identical test setup. Same gun, same range, same temperature, same chronograph, same pellets, same shooter. The only difference is that our Komplete was now shooting High Pressure Air.
Here’s the shot string. Again very consistent until the regulator set point was reached. After this the Muzzle Velocity dropped away as expected. (There’s no significance to the extra shots at the “tail” of the NitroAir graph. They just weren’t necessary for the HPA test.).
If we now combine both graphs at the same scale, we see the following. Our Komplete gave a slightly higher Muzzle Velocity when using High Pressure Air (green dots) in the PCP Conversion than it did with the NitroAir cartridge (red dots).
As all other parameters were the same, this slight difference must be due to the action of compressed air in the gun, compared to Nitrogen.
Next we’ll look at the same data but “zoom in” to part of the graph. Now we can see the differences – and similarities – more clearly.
We’ll analyze the data over 60 shots per fill. This is 5 magazines worth of pellets in .177 caliber and most people would probably re-fill at about this point if they wanted to stay on target.
When firing with High Pressure Air, our Komplete produced an average of 990.6 FPS for 60 shots. That’s an average Muzzle Energy of 18.8 Ft/Lbs in .177 caliber.
Looking at the green dots, we can see that the regulator set point was reached at about shot 50. After this point the Muzzle Velocity fell away rapidly.
Again the red dots show performance using NitroAir. As the graph makes clear, the regulator set point was reached at shot 54. After that, the FPS fell away more gradually than it did for High Pressure Air. The average of 976 FPS equated to an average Muzzle energy of 18.3 Ft/Lbs when using Nitrogen power.
Umarex Komplete PCP Conversion From Air Venturi – Summary
Overall, the Air Venturi PCP Conversion For Umarex Komplete works well. It provided very similar performance in the test gun to using one NitroAir cartridge.
Priced at $99.99, this PCP Conversion would pay for itself after about 522 shots, compared to using NitroAir cartridges. So long as you already have the HPA charging equipment!
Here’s the calculation…
NitroAir Cartridges $22.99/pack of two. Equals $11.50 each.
$11.50 x 8.7 = $100.05. So 8.7 NitroAir Cartridges cost the same as the PCP Conversion.
At 60 “good” shots per cartridge, 8.7 x 60 = 522 shots.
So you’ll break even after about one tin of pellets when using the Umarex Komplete PCP conversion in .177 caliber. After that you’re ahead compared to shooting NitroAir cartridges. But of course the equation will be a good deal less favorable if you do not already have a hand pump, HPA tank or compressor.
Here’s yet another reason that the Umarex Komplete is the most versatile air rifle ever in terms of its propulsion capabilities. The Air Venturi PCP Conversion is yet another reason to buy a Komplete.
It’s a great little gun!
