Key Features
- 10.5-Inch Threaded Barrel: Keeps the overall length short for easy handling in tight spaces and lets you attach a muzzle device or suppressor if your state allows.
- 7-Inch M-LOK Handguard: Gives you plenty of rail space for a light, laser, or foregrip without adding bulk. Great for new shooters learning to mount accessories.
- SBA3 Pistol Brace: Adjusts to fit different arm lengths, so a parent and teen can both shoot comfortably. Provides a stable cheek weld without being a rifle stock.
- Tungsten Cerakote Finish: Protects against rust and scratches from range trips or safe storage. Keeps the gun looking good even after years of use.
- Semi-Auto Action with 30-Round Magazine: Reliable cycling for plinking or training. One magazine is included, but it accepts standard AR-15 mags for easy spares.
Who It’s For
This pistol is built for families who want a compact firearm for home defense or range practice. New shooters will appreciate the lightweight build and adjustable brace. Experienced owners will like the threaded barrel and M-LOK compatibility for customization. It’s also a good choice for youth shooters graduating from a .22 to a centerfire platform, thanks to the manageable recoil of 5.56 NATO.
Pros & Cons
- Pro: Compact length makes it easy to store in a safe or carry in a range bag.
- Pro: SBA3 brace adjusts without tools, fitting multiple family members.
- Pro: Tungsten Cerakote finish is more durable than standard anodizing.
- Con: The 10.5-inch barrel produces more muzzle blast and flash than a 16-inch rifle, so ear protection is a must for new shooters.
