The Seekins Precision SP-10

Introduction to the Seekins Precision SP-10

The video centers on the Seekins Precision SP-10, a semi-automatic AR-10 pattern rifle configured with a 22-inch barrel. The rifle is presented as a special purpose rifle intended to reach out to longer distances while maintaining control and consistency. The SP-10 is chambered in 6.5 Creedmoor, emphasizing precision and extended-range capability. The discussion frames the rifle as a modern evolution of the AR-10 concept, designed to deliver repeatable sub-MOA performance and soft shooting characteristics. The host sets the stage for a closer look at the rifle’s components, ergonomics, and how its configuration supports both near and far engagements.

Optics, mount, and stock characteristics

The rifle is equipped with a Steiner 2.5-15x optic, chosen to cover both close and more distant engagements with clear, crisp glass. The scope is mounted in a lightweight SIG mount that is described as doing exactly what is needed without adding unnecessary bulk. The SP-10 uses a Seekins Precision rifle-length stock of the company’s own design. This full-length stock contributes to the rifle’s soft recoil impulse and controllability. During trials, the platform received strong feedback for being a soft shooter while maintaining repeatable sub-MOA accuracy. The combination of quality glass, a solid mount, and a well-designed stock is presented as central to the rifle’s precision role.

Ambidextrous controls and trigger performance

The SP-10 features fully ambidextrous controls, including the bolt catch, bolt release, charging handle, magazine catch, and safety selectors. This layout supports both left- and right-handed shooters and facilitates efficient manipulation from either side of the rifle. Particular attention is given to the trigger, which is described as having an exceptionally crisp break and a very short, tactile reset. The trigger characteristics are highlighted as a major strength of the platform, enabling quick and accurate follow-up shots. Together, the ambidextrous controls and refined trigger system are presented as key elements that enhance the rifle’s usability and consistency in precision applications.

Rail system, bipod, and gas block tuning

The SP-10’s handguard is described as Arca compatible or Arca ready, allowing flexible mounting options for support equipment. Attached to the rail in the video is an Accu-Tac bipod mounted via Picatinny, noted for its durability. The quick-detach setup allows the bipod to be removed easily if the shooter prefers to run a bag or other support. The rifle also incorporates a fully adjustable gas block, enabling tuning for different ammunition types, including hotter loads, handloads, or specialized ammunition. This adjustability is emphasized as important for optimizing reliability, recoil impulse, and overall performance across varying conditions and loads.

Flash hider, suppressor use, and handling

At the muzzle, the SP-10 is fitted with a three-prong flash hider. It is described as effective at reducing muzzle flash and also serving as a mounting interface to make the rifle a capable suppressor host. The rifle is shown with a suppressor installed, and the overall balance is noted as remaining even despite the 22-inch barrel and added weight of the can. The configuration is characterized as suitable for quiet, suppressed shooting without making the rifle unwieldy. The choice of flash hider is linked to the 6.5 Creedmoor chambering, which already produces lighter recoil than .308, further supporting controllable, suppressed fire.

6.5 Creedmoor vs .308 and platform history

The video explains that testing compared 6.5 Creedmoor, 6mm, and .308 Winchester, with 6.5 Creedmoor edging out the others due to lighter recoil, better ballistic efficiency, and overall performance. This leads into a brief history of the AR-10 platform, which initially struggled in early trials with reliability. The SP-10 is presented as a modern refinement, contrasted with platforms like the SR-25 that are commonly seen in special operations use. The SP-10 uses a heavy-duty bolt carrier group and a full-length flat wire spring to promote longevity, soft shootability, and repeatability. Development reportedly began in 2018, with the rifle entering service in 2019 and being used by specialized units, including CAG. The segment closes by revisiting the 6.5 Creedmoor versus .308 debate, with a preference stated for 6.5 Creedmoor due to softer recoil and superior ballistic coefficient.
