    Yes. It's inversely proportional. Look up Boyle's Law.

    Does "ballistic rated" mean they can stop a bullet without breaking?


    Quote

    Protector failure criteria will be based on any of the following:
    • Piece fully detaches;
    • Device fractures;
    • Penetration of the rear surface;
    • Lens not retained; or…
    • For the high velocity test, if any piece of the device sticks to contact paste or if contact paste is on
    the projectile or on the complete device.

    High Mass and High Velocity Impact forces to be tested remain essentially the same as the prior
    standard. The high mass pointed projectile is pointed and weighs 500 grams and is dropped from a height
    of 50 inches. The high velocity test uses a steel ball .25 inches in diameter that is fired at 150 feet per
    second at the lens in the test frame.

    One was a well known aftermarket brand, I won't say which. One was an APEX barrel (taking these pics requires destroying the barrel of course). I have others I could post up too, but they're all similar.
    Anodizing the aluminum creates this finish. If you look down the bore, they all look quite shiny and smooth, but they're not actually.</div>

    To give some scale to the above pics, here's 1mm gradations on a ruler-
