K31 OBM

K31 OBM

This K31-OBM is intended as an accessory to be used in conjunction with the existing K31 clamp on scope mount.

K31 Scope Mount NOT included!

 

The current K 31 Clamp On Scope Mount is manufactured to accept a wider variety of 3/8 inch clamps. The profile of the dovetail is slightly different to accommodate that. If you have an older K31 Clamp on Mount, this new OBM may not slide easily on those older dovetail rails. You may have to purchase one of the current Clamp on Scope Mounts to assure a perfect fit.

Slide the OBM over the K31 clamp on scope mount dovetail rail, and move forward until it stops. Using Blue Loctite, insert the three rail screws and tighten but do not over tighten! The Blue Loctite will keep them in place.

The next step is to slide the deflector into the provided space between the bottom of the OBM and the top of the K31 mount. There is a relief slot machined into the bottom of the unit provided for that purpose.

Now apply a light grease to the edge of the deflector and insert the 3 small deflector screws down against the crimped edge of the deflector and secure into place. Do not over tighten! Do NOT use Loctite on the screws
.-------------------------------------------------
Contrary to what you may have heard, the K31 rifles do not eject spent cases the same, one rifle to another. Your deflector is positioned and bent at the point of manufacture to work across a number of K31 rifles with 100% ejection. Yours may not, but you can find that "sweet spot" for ejection by using both hands to gently bend the deflector either up, or down. Bear in mind it takes very little bending to control the angle of the ejected case.

Should you have any questions related to the fit and function of this unit, please call the Swiss Products Helpline 406 858-2066
