Competition Side Rails, designed for the Matrix or ESR Chassis, provide enhanced stability when shooting “positional” in PRS or NRL Style competitions.

Adds approximately 75% more width to the bottom of the fore-end, making the rifle more stable when shooting off positional bags.  The radius section on the bottom of the rails provides a more comfortable grip of the fore-end when moving and changing positions.
