Competition Side Rails, designed for the BA Comp chassis, provide enhanced stability when shooting “positional” in PRS or NRL Style competitions.

System includes:
Left and right side rail
8 “t-nuts”
8 fasteners for attaching the rails to the nuts
8 fasteners for attaching to the MPA Internal Weight System.
