    Umarex Gauntlet: Super Tune Kit Installation (VIDEO)

    I am not disputing your experience with QB. Once the momentum of the hammer breaks over poppet inertia, poppet spring and air pressure , the surplus of that momentum controls the dwell timing of that valve. The small changes of the hammer spring tension could account for big changes of the...

I wish I took all of the measurements while it was apart. The seat diameter is a little over 5 mm. That is where I got 30 lb air pressure when closed. The air path around the poppet body is much larger than other much more restrictive air passages I don't understand the term "easier to...

I agree with this in theory. But in case of Gauntlet, if you enter numbers, the light poppet does not sound convincing. Kinetic energy of the hammer has to overcome: inertia of 8 gram original Gauntlet poppet, inertia of the poppet spring, force of the poppet spring 5 lb and air pressure 30 lb...

The weight and the shape of the original poppet could be easily altered on the lathe or drill. The air pressure on the valve poppet is a function of the surface of the valve port only and that did not change. My concern that a new poppet in the kit is a downgrade due to lack of the seal and a...

    First pcp airgun

    I would get a moisture filter for the pump. Also that brand of the pump is hard to pump above 2500 psi unless you are over 250lb.

    I am wondering about a poppet in the kit. As far as I could see it makes the spring a little relaxed. Would it be a better to shave the original poppet to recess the spring seat? At least it has a seal. Anxious to see the shooting test.
