Description

The BT78 – SIG SAUER® CROSS™ Buttstock Rail Kit is a 2.05″ 1913 Picatinny Rail that installs directly onto the folding buttstock of the SIG SAUER® CROSS™ rifle to allow for mounting of any of our PRM style of Accu-Shot Monopods.

Installation requires two factory 10-24 threaded holes spaced approximately 1.57″ apart as found on our sample SIG SAUER® CROSS™. No modification is required.

Comes with two 10-24 x 3/4″ flat socket cap screws as seen for use with SIG SAUER® CROSS™ polymer bag rider as seen in pictures. We do not have 10-24 x 1/2” for use without polymer bag rider. Use of a thread locker upon installation is suggested.

Machined to Picatinny rail standards from 6061-T6 aluminum with Mil-Spec Type III Class 2 finish. Available in black only.
