Fast, light and compact FN TSR XP (Tactical Sport Rifle - Extreme Performance) features Controlled Round Feed (except in 223 Rem.), blade ejection and a three-position safety. The three-lever Tactical Sport Trigger™ has an adjustable pull range from 3½ to 6 pounds and is factory set at an optimal 4½ pounds. All TSR XP and TSR XP USA (Ultra Short Action) rifles have cold hammer-forged MIL -SPEC fluted barrels. The one-piece steel MIL -STD 1913 optical rail has additional elevation built-in so optics have a greater range of adjustment at further distances. The Model 70-design forged steel receiver is available in ultra-short and short magnum action lengths and mates to a full aluminum bedding block molded into the FN /Hogue® synthetic stock that's covered with a textured OverMolded olive drab rubber surface.
