Ensio Firearms KAR-21 .223rem rifle with a 16” barrel. KÄRÄJÄMIES AUTOMATIC RIFLE. The KAR-21 is a modern rifle system designed to use two different calibers from the same firearm. With just one tool, you can switch calibers from .223 Rem to .308 Win.
Full-length, monolithic upper receiver made from a single piece, equipped with a Picatinny rail for secure mounting of optics and night vision devices. The rifle can accommodate a muzzle brake, suppressor, or flash hider. For suppressors, the firearm features an adjustable gas port – we recommend using blow-through suppressors. The rifle operation is designed for both right and left-handed shooters. Eight positions for versatile sling mounting
Compared to its competitors, it offers easier recoil management due to the barrel line being below the stock line.
Caliber Change
All in one firearm. Thanks to its patented solution, you can change the caliber from the short-range .223 Rem to the long-range .308 Win. Caliber change occurs with one hex wrench and by swapping out four parts.
Recoil and Control
Recoil management is incredibly easy, as the barrel line is positioned below the stock line. The firearm does not rise even during rapid fire.
Safety/fire selector and magazine release are located on both sides of the firearm. The charging handle side can also be switched, making it suitable for both right and left-handed shooters.
True Customizability
The firearm features a full-length MIL-STD-1913 Picatinny rail for mounting sights and night vision devices.
You can easily attach bipods, lights, rails, and other accessories to the M-Lok mounts on the sides and underneath of the firearm. The rifle is pre-equipped with multiple quick-detach sling mount points and HK-hook sling points.
Quick and Easy Field Disassembly
Easily and quickly disassemble, clean, and maintain your firearm. In field disassembly, no small, easily lost parts come off nor do springs fly around. You can perform the disassembly entirely without tools.
We believe that when maintaining the firearm is easy, service will be done more frequently, thus extending the lifespan of both the firearm and barrel.
