Description

BEST Fittings have responded to customer demand and produced this bespoke kit to convert your SIG SAUER MCX or MPX to run on High Pressure Air (HPA).

NEW 1100 psi Output Regulator.

With all of the components included in one low cost package, all you need is a dive cylinder or stirrup pump to fill the tank. No additional parts will be required to complete your conversion.

Weighing in at only 650g there is hardly any difference when compared to a full 88g cartridge and the standard butt-stock. (565g)

All of the parts of the kit are also available separately should you already have purchased one of our adaptors.

Tank Only.

Adaptor Only.

Butt Stock Only.

Filling Connector.

During trials, we discovered that fast fire capability was not so much about pressure, but more importantly it’s about air flow. We trialled our own standard Air Magnum to Co2 or HPA adaptor with actuating pin, and found that even increasing regulator pressure to 1100psi, the fast fire capability was very unreliable.

We then re-designed the HPA Adaptor with a fast flow actuator, and fast fire capability with a standard 750 – 850 psi regulator output was achieved. A great result in our book!

However, following up on customer feedback, and further product research, we have concluded that although fast fire capability is possible, a drop in performance is also noted when running at the lower 750 – 850 psi regulator output, so we now supply our kit with a NEW 1100 psi Output Regulator.

As a service to customers that have already purchased one of our kits with a standard 750 -850 psi regulator, we are happy to modify your existing bottle and return it to you. If you would like to take advantage of this service, simply send an email to: [email protected] and we will explain the procedure for returning the bottle.

IMPORTANT NOTES:

  • We recommend that one or two drops of silicone oil be placed into one of the holes in our bottle adaptor between recharges to maintain good internal lubrication of the action. DO NOT OVER LUBRICATE!
  • The weapons were designed for use with Co2, and the operating pressure of Co2 varies greatly:Co2 @ 22ºC is approx 855PSI
    Co2 @ 30ºC is approx 1050PSIThe regulators are fitted with a Burst Disk on both the Low and High pressure side of the regulator. In the highly unlikely event of the regulator failing, the low pressure (1.8KPSI) burst disk would rupture and vent the bottle contents through the Burst Disk Port. It is commonplace in industry to use Regulated High Pressure Air bottles in Co2 applications, as the gas is far more stable under changes in temperature.
  • You may invalidate the manufacturer warranty in fitting this upgrade, and do so at your own risk.

    Converted my Sig MPX using this kit,It works very well and only adds a bit to the weapons overall length.The supplied stock cover fits well and the valve is clear and easy to see.
    The valve convertor fits like a glove.The bottle is top quality.
    I haven’t noticed a drop in round velocity and the unit came in record time and was extremely well packaged..
    Best Fittings are an absolute pleasure to deal with and I would use them again without hesitation and would recommend them
    Sam and his staff are the gold model with regards to customer service.
    I have absolutely no connection with this company just a satisfied customer
