Key Features
- Carbon Fiber Tension Barrel: This 18-inch match-grade barrel is wrapped in carbon fiber, reducing weight while maintaining rigidity. Why it matters: You get the accuracy of a heavy barrel without the extra pounds, making it easier to carry in the field or steady on a bench.
- TriggerTech Trigger: A crisp, adjustable trigger that breaks cleanly with minimal overtravel. Why it matters: Consistent trigger pull means tighter groups, especially in rimfire competition where precision is everything.
- Folding Stock with Adjustable Cheekpiece and Length of Pull: The stock folds to the right, cutting the rifle’s length by about 8 inches for compact storage or transport. The cheekpiece and length of pull are tool-free adjustable. Why it matters: You can dial in a perfect fit for any shooter, and the fold makes it easy to pack in a backpack or case.
- Threaded Muzzle (1/2x28): The barrel is threaded and comes with a thread protector. Why it matters: Add a suppressor or muzzle brake to reduce noise and recoil, making training or small-game hunting quieter and more pleasant.
- 10+1 Detachable Magazine: Uses a flush-fit, 10-round rotary magazine. Why it matters: Reloads are quick and controlled, and the flush design keeps the profile clean for carry.
Who It’s For
This rifle is for the rimfire shooter who wants a high-end, accurate platform without the bulk of a traditional target rifle. It’s ideal for competitive shooters in NRL22, PRS Rimfire, or local club matches. It also suits small-game hunters who need a lightweight, packable rifle for walking through brush or climbing into a tree stand. New shooters will appreciate the adjustable stock and crisp trigger, while experienced shooters will value the carbon fiber barrel’s consistency.
Pros & Cons
- Pro: Sub-MOA accuracy with quality .22 LR ammunition, verified by multiple shooters in the field.
- Pro: Lightweight at 5.1 lbs, making it one of the lightest precision rimfire rifles available.
- Pro: Folding stock is rock-solid when locked, no wobble.
- Con: The carbon fiber barrel can heat up faster than a steel barrel during rapid fire strings, so it’s best for slow, deliberate shooting or competition stages with limited rounds.
