Seekins Precision SIC: Special Operations Modular Precision Rifle

The SIC was not designed in a vacuum. Seekins Precision developed this platform to meet specific U.S. Special Operations requirements: a single rifle that operators could reconfigure in the field for different mission profiles, from 6.5 Creedmoor for medium-range precision work to .338 Lapua for extended engagements past 1,500 meters.

Bryan Morgan from Hat Creek training participated directly in the SIC's development and testing cycle, running the platform through live-fire sessions in cold Idaho conditions. The results: consistent sub-MOA accuracy across caliber swaps, and a rifle that holds zero after repeated barrel changes. That kind of repeatability is what separates a professional tool from a novelty modular concept.

"Special Operations requirement" is a phrase manufacturers overuse. In this case, it translates to concrete design decisions: environmental hardening (FDE Cerakote over the entire platform), field serviceability (one T25 driver for every operation), reliability in temperature extremes, and a caliber swap workflow that does not require a bench or vice. Every feature on the SIC traces back to an operational demand, not a marketing checkbox.

The SIC's modularity is built around three core swappable assemblies: barrel, bolt, and magazine well. The receiver, grip, trigger assembly, and stock remain constant across all caliber configurations. Takedown pins, not screws, connect the removable grip and trigger assembly to the receiver. This means the entire fire control group lifts out for cleaning or replacement without threading a single fastener.

The bolt uses a 3-lug design with a 60-degree throw, shorter than the traditional 90-degree bolt lift found on most precision actions. It is toollessly removable for field cleaning or caliber swap. Each caliber gets its own bolt face, so swapping from .308 Winchester to .338 Lapua requires changing the bolt along with the barrel and magwell.

Magazine wells are caliber-specific and swap without tools. The short-action calibers (6.5 Creedmoor, .308) use one magwell configuration; the long-action magnums (.300 Win Mag, .300 PRC, .300 Norma, .338 Norma, .338 Lapua) use another. This approach eliminates the feed reliability problems that plague universal-magwell designs trying to accommodate both short and long cartridges in the same feed path.

The SIC spans the full spectrum from short-action precision cartridges to long-action magnums. The short-action side covers 6.5 Creedmoor and .308 Winchester, the two most popular precision calibers for match shooting and general-purpose work inside 1,000 meters. Both use the same magwell and offer the best magazine capacity for their respective cartridge lengths.

The long-action options get more specialized. The .300 Win Mag and .300 PRC fill the 1,000 to 1,500 meter gap with supersonic performance and widely available ammunition. The .300 Norma (1:8 twist) pushes heavier projectiles at similar velocities with a shorter, fatter case optimized for modern bullet designs. At the top of the range, .338 Norma and .338 Lapua (both 1:9.4 twist) deliver the energy retention and wind resistance necessary for engagements well past 1,500 meters.

All barrels use Seekins' carbon fiber wrapped construction over a 416R stainless steel core. The bore is single point cut rifled and hand lapped, the same process used by custom barrel makers charging $500+ for a blank alone. Flats machined into the barrel exterior provide the indexing surfaces for repeatable barrel changes. This is not a screw-in barrel system; the flats ensure consistent headspacing and alignment every time a barrel is installed.

The SIC's forend integrates a full-length ARCA rail running the entire length of the handguard. ARCA has replaced traditional sling studs and bipod adapters in the precision rifle community because it allows infinite bipod positioning along the forend without discrete mounting points. Any ARCA-compatible bipod or tripod head clamps directly to the rail and slides to the exact balance point the shooter needs.

M-LOK slots run along both sides of the forend for accessory mounting: night vision illuminators, laser aiming devices, or barricade stops. The integrated 20 MOA scope base sits on top of the receiver, with a matching full-length Picatinny rail extending forward along the handguard. This continuous top rail serves a specific purpose: aligning thermal or night vision clip-on devices in front of the primary optic without introducing a separate rail section or adapter that could shift zero.

The folding stock reduces the 47-inch overall length to 37.5 inches for transport. A dedicated bolt handle cutout in the folded stock prevents the bolt from catching or binding during the fold. The cheek piece adjusts for both height and cant, accommodating different optic mounting heights and shooter preferences. The butt pad adjusts for length of pull and angle, and it houses the integrated T25 tool, the only driver needed for caliber swaps and routine maintenance.

The ambi safety selector doubles as a thumb shelf, giving the shooter a consistent thumb position during precision shots. This is a small detail that makes a measurable difference when shooting from awkward field positions where a consistent grip matters more than it does on a flat range.

Seekins spec'd a TriggerTech Diamond 2-stage for the SIC. The Diamond is TriggerTech's top-tier action, using their Frictionless Release Technology where a roller bearing replaces the traditional sear-to-hammer friction surface. The result is a trigger break with zero creep and zero overtravel, consistent pull after pull regardless of temperature or lubrication state.

The 2-stage configuration gives the shooter a distinct take-up phase before hitting the wall, then a clean break. This matters on a precision platform because it provides positive trigger control under stress: the first stage confirms the shooter's finger is properly placed, and the second stage breaks without disturbing the reticle. Pull weight is user adjustable, so shooters can tune the break to their preference without replacing the trigger or sending the rifle back.

The trigger assembly, along with the grip, removes as a single unit via takedown pins. No screws, no thread-locking compound to deal with. This means the same TriggerTech Diamond stays with the rifle across all seven caliber configurations, providing an identical break regardless of whether the SIC is running 6.5 Creedmoor or .338 Lapua.

The SIC ships configured in a single caliber. Additional calibers require purchasing a Caliber Change Kit, which includes the barrel, bolt, and magwell for that specific cartridge. This keeps the base rifle price at $8,900 rather than bundling components most buyers would not use immediately.

The field swap workflow is straightforward. Open the action, remove the bolt (toolless, pull and rotate). Use the T25 from the butt pad to release the barrel. Swap the magwell by hand. Install the new barrel, torque with the T25, drop in the caliber-specific bolt, and confirm headspace. The entire process takes under 10 minutes with practice and does not require a bench, vice, barrel wrench, or any tool beyond the T25 stored in the rifle itself.

The rifle ships with a custom laser-cut weatherproof case sized to hold the SIC and at least one additional Caliber Change Kit. This is not a generic foam-lined case; Seekins cut the foam to the exact profile of the rifle, spare barrel, and accessories. It is a practical detail that reflects the rifle's intended use as a deployable system, not a safe queen.
