Key Features
- Peak 44 Blacktooth Stock — Hand-painted, one-of-a-kind camo pattern plus integrated Spartan Precision adapters for ultra-light bipod or tripod mounting without extra hardware. Why it matters: you save ounces and gain rock-solid stability on uneven terrain.
- Deep Spiral-Fluted Bolt — Reduces weight and bearing surface area for a smoother, more reliable bolt cycle even with gloved hands. Why it matters: faster follow-up shots and less fatigue during long stalks.
- Titanium Accubrake ST — Machined from titanium, this 2″ brake tames the 280 AI’s recoil to roughly a .243 Win level. Why it matters: you stay on target for quick second shots without flinching.
- TriggerTech Adjustable Trigger — Factory-set at 2.5 lbs, adjustable down to 1.5 lbs. Why it matters: a crisp, clean break eliminates trigger pull error at 600+ yards.
- Threaded Muzzle with Brake — Factory-installed brake is removable for suppressor use (5/8-24 threads). Why it matters: future-proof your setup without gunsmithing.
Who It’s For
This rifle is built for the backcountry hunter who hikes miles in steep country and needs a lightweight, accurate rifle that won’t let them down. It’s also ideal for the precision shooter who appreciates the 280 Ackley Improved’s flat trajectory and wind-bucking performance. If you carry a rifle daily in a pack or sling, the sub-7-pound weight and hand-painted stock make it a practical tool, not a safe queen.
Pros & Cons
- Pro: Sub-7-pound weight with full-length barrel and brake — rare in this class.
- Pro: Hand-painted stock means no two rifles look alike; adds character.
- Pro: Titanium brake is light and effective; reduces felt recoil by 30%+.
- Con: The 280 AI is not a common off-the-shelf caliber — you may need to handload or order ammo ahead of time.

Frequently Asked Questions
What twist rate does the barrel have?
The 22″ barrel has a 1:8 twist rate, optimized for 140–168 grain bullets common in the 280 AI. This stabilizes long, high-BC projectiles for extended range.
Is the muzzle brake removable for a suppressor?
Yes. The Accubrake ST is threaded on (5/8-24) and can be removed with a wrench. The barrel is already threaded for direct-thread suppressors.
Can I change the trigger pull weight myself?
Yes. The TriggerTech trigger is user-adjustable from 1.5 to 2.5 lbs using a small Allen wrench. No gunsmith required.
Does the stock come with sling swivel studs?
No traditional swivel studs — the stock has integrated Spartan Precision adapters. You’ll need a Spartan-compatible bipod or adapter for standard slings.
How does the 280 Ackley Improved compare to 7mm Rem Mag?
The 280 AI shoots flatter with less recoil, using 140–168 grain bullets at 3,000+ fps. It’s a handloader’s dream for long-range hunting.
