The large-frame AR platform has earned its place among serious hunters, precision competitors, and tactical shooters who need more than a standard AR-15 can deliver in terms of caliber capability and long-range performance. The Seekins SP10 Rifles bring Seekins Precision's manufacturing quality and thoughtful engineering to the large-frame AR format — delivering a well-balanced, reliable platform that works across the full range of applications that serious shooters demand from a large-frame build.

IRMT Upper and Ambidextrous Lower

The Seekins Precision SP10 starts with the IRMT upper receiver — Integrated Rail Mounting Technology — which features a built-in Picatinny rail at the 12 o'clock position, machined as a single unit with the upper receiver. That one-piece rail eliminates the flex and movement that add-on rail sections introduce, keeping your optic on a rigid, stable platform that maintains repeatable accuracy through hard use and variable conditions. The SP10 lower receiver features fully ambidextrous controls that make the rifle equally natural to operate for right and left-handed shooters without awkward hand positioning or extra motion.

Adjustable Gas Block for Versatility

The Seekins SP10 low-profile adjustable gas block is one of the features that serious shooters appreciate most — giving you the ability to tune the gas system for different ammunition types, match loads, hunting rounds, and suppressor use. Proper gas tuning makes the rifle cycle smoother, feel softer, and perform more reliably across the range of loads you actually run rather than being optimized for one specific load and marginal with everything else.

10X Stock and Advanced Tactical Compensator

The Seekins Precision rifles 10X Stock uses high-impact composite construction to keep weight down while maintaining strength across temperature extremes and rough handling. Adjustable length of pull and cheek height let you dial in the fit for your specific body dimensions and shooting position — prone, bench, or field positions all benefit from a stock that actually fits the shooter behind it. The Advanced Tactical Compensator cuts muzzle rise and felt recoil to keep follow-up shots fast and on target — a meaningful advantage in timed competition stages and when hunting fast-moving game where the second shot opportunity matters as much as the first.

SP10 and SP10M Configurations

The Seekins SP10M configuration adds features and refinements to the SP10 platform for shooters seeking the most capable version of the Seekins precision SP10 for precision and competition applications. The SP10M delivers the same reliable foundation with upgrades that competitive shooters and precision hunters specifically value.
