This mount was designed for use with the Williams FP-GR TK peep sight.
The corresponding front sight and block from Williams are:
Lyman Globe Front Sight
Williams Rear Sight

Top of the receiver to the top of the rear sight dovetail is .330"
Top of the receiver to the top of the picatinny rail is .45"

This rail is ambidextrous.
This mount is milled on both sides for bolt clearance on left or right handed models.

Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories. The channel in the center reduces the overall mass of the mount. Also, in many cases, it will not obstruct usage of factory iron sights. Our one-piece scope mounts are the obvious choice for hunters and tactical shooters alike.

We machine these in our shop using one of our machining centers. After machining, the mounts are tumbled, sand blasted, and Type II anodized for long lasting durability.

Installation: We recommend 20 inch lbs of torque and a drip of blue loctite (loctite is available through our website and is sold separately).

The entire mount and accessories (from the mounting screws and wrench down to the packaging) are made in the USA.
