Adapter Mount Picatinny Rails fasten to the accessory mount points on
the sides of Mesa Tactical High-tube and Low-tube telescoping stock
adapters, not on the shotgun receiver. The can also be used with our
new barrel and magazine clamps, which feature the same mounting hole
patters as our stock adapters.
Standard profile rails like the Stubby adhere to the minimum height
requirement of the MIL-STD-1913 specification, and should not be used
for mounting optics with the High-tube telescoping stock adapters.
Tall profile rails are designed to mount optics for use with
High-tube telescoping stock adapters, or to mount accessories slightly
away from the receiver when fastened to the telescoping stock adapter
side accessory mount points. When used for optics, the elevation of the
tall profile rails is similar to that of a flat top AR-15.
Adapter Mount Saddle Rails
Our adapter mount saddle rails are secured to both sides of a
telescoping stock adapter, cantilevering forward over the receiver.
They provide a convenient means of attaching a Picatinny sight rail to
shotguns equipped with our Low-tube telescoping stock adapters; or, for
High-tube adapter shotguns, an alternative to the sight rail screwed
into the top of the adapter. No alterations to the shotgun receiver are
required.
Designed
for zero magnification optics, these saddle rails work best with red
dot scopes, reflex optical sights and other low magnification sights.
The rails can be fitted onto Remington 870s with Low-tube adapters
and Wilson Combat ghost ring sights, allowing the iron sights to act as
back-up for a scope.
