Seekins Precision SP10 Features The Seekins Precision SP10 complete upper in 6.5 Creedmoor is engineered to extract the full accuracy potential of the 6.5 Creedmoor cartridge through a precisely fitted 22 barrel with a 1:8 twist rate that stabilizes everything from lightweight varmint bullets to heavy 140+ grain long-range projectiles with consistent precision. Seekins Precision manufactures each SP10 upper to match-grade tolerances with tight fitment standards that reduce play between the upper and lower and contribute directly to shot-to-shot consistency at extended ranges. The 6.5 Creedmoor chambering provides a decisive advantage in wind deflection and retained velocity over legacy .308 Win and .30-06 loads at ranges beyond 600 yards making the SP10 a genuine long-range competitor. For precision rifle builders and PRS competitors who want a factory-built AR-10 upper with the accuracy of a custom build the SP10 delivers where it matters most. The Flat Dark Earth finish gives the Seekins Precision SP10 a distinctive field-ready appearance while contributing to the upper s corrosion resistance and durability in demanding environments from desert hunting country to wet Pacific Northwest terrain. At 10.5 lbs the SP10 carries the heft expected of a serious long-range AR-10 upper with a 22 barrel providing a stable and recoil-absorbing platform that aids in maintaining sight picture for rapid follow-up shots on target. Seekins Precision s reputation for precision CNC machining and rigorous quality control is on full display in the SP10 upper which is engineered to be a direct drop-in solution for compatible AR-10 lowers without fitting or modification.
