Key Features
- Quick-Change Barrel Collar: This patent-pending system lets you swap barrels without special tools, so you can switch from 308 Win to another caliber or replace a worn barrel in minutes. Why it matters: It saves you time and money on gunsmith fees, and keeps your rifle running season after season.
- Three-Lug Bolt with 60-Degree Throw: The short, 60-degree lift gives you faster bolt manipulation for quick follow-up shots on game or targets. Why it matters: A smoother, faster cycle means less time between shots, which is critical when you need a second round on target fast.
- Carbon-Wrapped 416R Stainless Barrel: The carbon wrap reduces barrel weight while the 416R stainless core delivers match-grade accuracy and resists corrosion. Why it matters: You get a lightweight barrel that doesn’t walk when it heats up, keeping your groups tight even during a string of fire.
- PH3 Carbon-Composite Stock with Full-Length M-LOK: The stock is lightweight, stiff, and has M-LOK slots along the forend for mounting bipods, rails, or sling hardware. Why it matters: You can attach exactly the accessories you need without drilling or adding heavy rails, keeping the rifle light and balanced.
- Hybrid Aluminum-and-Steel Action: The action uses an aluminum body with steel inserts at critical wear points, reducing weight while maintaining strength and smooth operation. Why it matters: It cuts ounces without compromising the lock-up or reliability you need for precision shooting.
Who It’s For

If you’re looking for a rifle that balances packability with accuracy, this is it.

FAQ
What is the twist rate on the 16-inch 308 Win barrel?
The 16-inch barrel has a 1:10 twist rate, which stabilizes most 308 bullets from 150 to 180 grains well.
Can I swap to a different caliber with the quick-change system?
Yes, Seekins offers barrel kits for various calibers including 6.5 Creedmoor and 223 Wylde. The system uses a simple collar, no gunsmithing required.
Is this rifle optics-ready?
The receiver comes with a 20 MOA Picatinny rail, so you can mount any scope with standard rings or a one-piece mount right out of the box.
What is the magazine capacity?
It uses AICS-pattern magazines, typically 5-round or 10-round, depending on your state laws.
How does the 60-degree bolt throw help in the field?
It reduces the distance your hand moves to cycle the bolt, which speeds up follow-up shots and keeps the rifle more stable during rapid firing.
