Competition Side Rails – Matrix/ESR

Please allow 1-2 weeks for shipping

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.

Side rails set weights 1.1 lbs.

The side rails are compatible with MPA weight tuning system and the Gray Ops CNC Side Rail Weights made specifically for the ESR/Matrix Comp Side Rails, available for purchase separately.

• Left and right side rail
• 8 “M-lok Nuts”
• 8 fasteners for attaching the rails to the nuts
