throw, enhance face-to-stock contact, etc.
detachability and return to zero without
extraction (and possible loss) of any screw or

extension, when needed, achieved through base
design rather than ring design, the economical
but much less stable "solution" adopted
by other mount makers.
four-point attachment to factory-drilled gun

for ring lining, PSA pads are
provided with rings for shooters wary of
metal-to-metal contact with expensive scopes.
