BEST Fittings have responded to customer demand and produced this bespoke adaptor to convert your SIG SAUER MCX or MPX to run direct from a screwed in Co2 or HPA Paintball tank. It does require the removal of the stock in most cases, and additional parts will be required to complete your conversion.

During trials, we discovered that power output and 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 body of the unit, and designed a fast flow actuator, and discovered that we had achieved fast fire capability with a standard 850 – 900psi regulator output. A great result in our book!

We are also producing a dedicated paintball remote line connection kit that allows you to keep the stock on the gun and run your paintball remote to the stock. A very minor and easy to do stock modification is required.

IMPORTANT NOTE:

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 advise operating this unit with a regulator running at 1100 psi +/- 50psi.

We recommend that 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!
