Key Features

- Carbon Fiber Tension Barrel — why it matters: minimizes barrel harmonics and heat shift, keeping shots consistent even during rapid strings at the range.
- Adjustable Carbon Fiber Cheek Piece and Length-of-Pull — why it matters: lets you dial in a perfect cheek weld and reach for any shooter size or shooting position.
- FFT Carbon Fiber Handguard with M-LOK Slots — why it matters: gives you a lightweight, rigid platform for mounting lights, bipods, or sling mounts without adding bulk.
- Threaded Muzzle (1/2×28) — why it matters: accepts standard .22 suppressors and muzzle brakes, making it quiet-friendly for training or pest control.
Who It’s For
This rifle is built for shooters who want a lightweight, packable rimfire that can handle precision work at 50-100 yards. It’s a great fit for new gun owners looking for a trainer that mimics the feel of a centerfire AR, without the recoil or cost. Small-game hunters will appreciate the accuracy and portability for walking fields or timber. Competition shooters in NRL22 or PRS Rimfire will find the adjustable stock and carbon barrel give them an edge on the clock.
