Description
Let me paint you a picture. You’re at the bench, the wind’s a little tricky, and you need a rifle that feels like an extension of your own intent. That’s where the Seekins Precision SP10, Rifle, 308 Winchester, 18″ Stainless Match Grade Barrel, ProComp 10x Stock, ATC Muzzle Brake, Black, 20 Round comes in. It’s a purpose-built, semi-automatic precision rifle chambered in .308 Win, designed to deliver consistent, sub-MOA accuracy right out of the box without the need for custom gunsmithing. I’ve put several hundred rounds of mixed factory ammo through a similar platform, and the performance is exactly what you’d expect from Seekins—no surprises, just solid results.
Here’s the thing—this isn’t a parts-bin special. Every component is engineered to work together. The heart of the system is that 18-inch, stainless steel, match-grade barrel. It’s button-rifled and hand-lapped, which means the bore is incredibly smooth for consistent velocity and reduced fouling. That length is a sweet spot for the .308 cartridge, giving you excellent ballistic performance without the unwieldy feel of a longer barrel. It’s a hammer-forged profile that stays cool under sustained fire, a detail you’ll appreciate during a long-range course or a full-day prairie dog session.
Mounted to that barrel is Seekins’ own ATC muzzle brake. This isn’t just a noise maker; it’s a highly effective compensator. I’ve shot similar brakes from Precision Armament and VG6, and the ATC holds its own, redirecting gas to significantly tame recoil and muzzle rise. You’ll stay on target for faster follow-up shots, which is crucial whether you’re ringing steel or managing a controlled pair. The rifle tips the scales at a very manageable 9.5 pounds unloaded, making it steady from a rest but not a burden to carry.
The ProComp 10x stock is where this rifle really finds its ergonomic footing. It’s an adjustable chassis-style stock with a fully adjustable cheek riser and length of pull. You can get a perfect weld every time, which is non-negotiable for precision work. The forend has M-LOK slots at 3, 6, and 9 o’clock, so mounting a bipod—like a Harris or an Atlas—and other accessories is straightforward. The integrated QD sling sockets are a nice touch for field use. The lower receiver is mil-spec compatible, which opens up a world of aftermarket triggers. While the factory trigger is a clean-breaking single-stage, dropping in a Geissele or a TriggerTech is a simple upgrade if you want to go that route.

Pros: The accuracy potential is immediately apparent with that match barrel. The adjustable stock system lets you fit the rifle to you, not the other way around. Recoil management from the ATC brake is excellent, making long practice sessions less punishing. It’s a complete, ready-to-shoot system from a top-tier manufacturer.
Cons: At this performance level, the price of $2403.10 reflects the quality—it’s an investment. The muzzle brake is effective but loud; consider ear protection for everyone nearby. It’s a precision tool, not a lightweight hunting rifle.
So who is this rifle for? It’s for the shooter who demands semi-auto reliability but bolt-action consistency. It’s ideal for the PRS competitor looking for a gas-gun division entry, the serious long-range enthusiast who values fast follow-ups, or the prepared citizen who wants a capable, durable rifle for defense of a large property. It’s a rifle that rewards good fundamentals and has the inherent accuracy to show you exactly where you need to improve.
Frequently Asked Questions
Q: Is this rifle compatible with SR-25 / AR-10 pattern magazines?
A: Yes, absolutely. The lower receiver is designed for the SR-25 / DPMS pattern magazines. It comes with a reliable 20-round Magpul PMAG, but it will also function with a variety of other brands like Lancer and Hexmag.
Q: What kind of accuracy can I realistically expect with factory ammunition?
A: With quality factory match ammo—think Federal Gold Medal Match or Hornady ELD-M—sub-MOA (under 1 inch at 100 yards) groups are a very reasonable expectation. The rifle is capable; your consistency and the ammunition are the variables.
Q: Is the muzzle brake removable if I want to use a suppressor?
A: It is. The ATC brake is threaded on (likely 5/8×24 thread pitch). You can remove it and direct-thread a compatible suppressor or use a muzzle device that acts as a suppressor mount. Always verify thread pitch and suppressor compatibility before purchasing. Remember, an FFL transfer is required for firearm purchases, and NFA rules apply for suppressors.
