Key Features
- B5 Bravo Stock and Grip — WHY IT MATTERS: Provides a comfortable, stable cheek weld and a positive grip angle for repeatable accuracy, especially for youth shooters or those with smaller hands.
- M-LOK Polymer Handguard — WHY IT MATTERS: Lets you attach lights, lasers, or a foregrip without adding heavy rail sections, keeping the rifle light and balanced for all-day range sessions.
- Threaded Barrel with A2 Flash Suppressor — WHY IT MATTERS: Allows easy mounting of a .22 LR suppressor or muzzle brake, reducing noise and recoil for a more pleasant shooting experience.
- Magpul MBUS Folding Sights — WHY IT MATTERS: Durable, low-profile backup sights that fold flat when not needed, giving you a clean sight picture and reliable zero retention.
- 25-Round Magazine Capacity — WHY IT MATTERS: More time shooting, fewer reloads. Perfect for training drills, competition stages, or casual plinking with the family.
Who It’s For
This rifle is ideal for families teaching safe firearm handling, new shooters learning AR-platform controls, and experienced owners looking for an affordable trainer that mirrors their centerfire AR-15. The low recoil and light weight also make it a great choice for youth shooters and smaller-framed adults.
Pros and Cons
Pros: Accurate out of the box; reliable with standard-velocity .22 LR; easy to clean; familiar AR-15 ergonomics; M-LOK handguard for accessories; threaded barrel for suppressors.
Cons: Polymer handguard can flex under heavy accessory loads; some shooters prefer a free-float handguard for maximum accuracy potential.
