Worried about damaging Crucial Parts Running CSS puck

[theorangeplanet 968]

A CSS tappet with a concave face would increase the power transferred to the piston. I had assumed (incorrectly) CSS was trying to increase surface area on the face, like KA & MD, but the nipple facing backwards gives the CSS tappet the same length as a regular puck but with less weight. Since it has less mass it can be moved with less force than the standard puck but still contacts the piston at the same time as the standard puck.

 

The KA & MD pucks have a concave face, giving them more surface area than a flat face of the same diameter, which means less force is required to move it than a standard flat faced puck. A CSS puck with a concave face, KA or MD puck with a nipple, would have both the reduced mass AND larger surface area on the face. That would be one fast moving puck! Combine that with an auto gas plug & you could shoot 22's & your bolt would probably still cycle.

 

IIRC, Mike stated in his booster puck thread that the 'boosting' effect of his puck had more to do with the weight than the shape... hence why his 'booster puck' and 'stainless puck' are the exact same shape, just different weights.

The CSS puck is longer than a normal puck. That is how it works. The MD puck works off of being lightweight. The KA puck works of of a dished face, although its effect is controversial; some say it works great, some say it makes no difference.
