All Precision Armament Scope Rails are fully machined from a billet of ultra-strength Tennalum® 7068, offering the strength of steel at a third of the weight. Billets are stress relieved and pre-ground prior to machining to deliver exceptional straightness. Manufactured to MIL-STD 1913 dimensions with all critical contact surfaces held uniform to within 0.0003". Fully CNC chamfered along every edge for smooth, snag free handling. Features an integral recoil lug combined with elongated mounting holes for positive lug engagement and elimination of movement under heavy recoil. Unique cross section geometry is fully FEA optimized for maximum stiffness-to-weight ratio while also providing improved ejection port access. All bases have built in 20-MOA of elevation for extended range shooting. Mil-A-8625 hardcoat anodized matte black finish.
This scope rail will fit all FNH model SPR, TSR, & PBR receivers.
Designed to fit standard/factory receivers with four-screw mounting configurations. Also features two additional mounting holes for 'optional' gunsmith drilling and tapping of receiver for extra strength six screw configuration.
Includes six 8-40 torx screws and installation guide. Requires a T10 torx wrench for scope rail installation.
