Older model X-Bolts had front screw holes that were threaded to the top of the receiver. Newer models now have a deeper countersink. This countersink prevents the mounting screws from engaging multiple threads and can cause the holes to strip out in the receiver. We have changed the depth of the countersink on mounts made after January 2021. The date code can be found on the bottom of the mount. If the last 2 digits are 21 or higher, your mount has the deeper countersink.

Older mounts may require longer front screws. We recommend test fitting the screws before Loctiting to check for proper engagement. If the screws only engage with one thread, please contact us and we will provide longer screws (.335” OAL). If the screws bottom out before tightening the mount, we recommend removing a bit of material from the screw. The front screws can be torqued to 10 in/lbs.

We recommend measuring the hole spacing in your receiver to confirm it matches with the dimensions we have published.

Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories. Our one-piece scope mounts are the obvious choice for hunters and tactical shooters alike.

This mount is a Picatinny-style base and compatible with Picatinny or Weaver scope rings.

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

We recommend:
0 MOA - if shooting 0-500 yards
20 MOA - if shooting 500-1000 yards

When zeroing your rifle with a 20 MOA mount, we recommend zeroing at 200 yards.

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.
