With the help of y'all, we can make this an informative thread for those seeking mounting hardware info for our beloved AN/PVS14
Alas I only have two, a USGI and a PRI.
The PRI mount is height adjustable, it will clear most of the rear BUIS. Pictured is a Troy rear BattleSight, with the PRI mount at its lowest setting
PRI mount at its highest adjustment.
The indentations/grooves for height adjustment.
The front of the PRI mount, probably should have numbers etched along with the increments. Curiously, these little lines are in Inch, though they appear to be in milimeter
Here's a USGI mount. It's a cantilever mount with a big mounting screw wheel below that effectively eliminates any possibility of using a flip up BUIS with it unless you mount it IN FRONT OF the BUIS or mod the mounting screw wheel
From what I hear, the rationale behind this is you'd take the whole thing off and put the A3 removable carry handle on as your BUIS. The nut that's supposed to cap the end of the thumb screw (above the letter TOOL) is missing. It's a terrible way to secure the mount on the rail
