KAR 21 .308Win Self-Loading Rifle

Ensio Firearms KAR-21 .308Win rifle with 16” / 20'' barrel. KÄRÄJÄMIES AUTOMATIC RIFLE. The KAR-21 is a modern rifle system designed to use two different cartridge sizes from the same firearm. Caliber conversion from .223 Rem to .308Win can be done with just one tool.

Fully integrated, single-piece monolithic upper receiver with a Picatinny rail allows for secure mounting of optics and night vision devices. The firearm can accommodate a flash suppressor, sound suppressor, or muzzle brake. The adjustable gas port is designed for suppressors - we recommend using blow-through suppressors. The firearm is designed for both right- and left-handed use. Eight locations for versatile sling mounting.

Compared to its competitors, recoil management is easier due to the line of sight being below the buttstock.

Caliber Conversion
All in one firearm. Thanks to patented technology, you can convert the firearm's caliber from short-range .223 Rem to long-range .308Win. Caliber conversion requires one hex wrench and swapping four parts.

Recoil and Control
Recoil management is incredibly easy, as the firearm's line of sight is below the buttstock. The firearm does not attempt to 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 swapped. This makes the firearm suitable for both right- and left-handed shooters.

True Customization
The firearm features a full-length Stanag 4694 Picatinny rail for mounting optics and night vision devices.
You can easily attach shooting bipods, lights, rails, and other accessories to the M-lok mounts on the sides and beneath the firearm. The firearm comes with several attachment points for “Quick Detach” and “HK-hook” sling swivels at the front, middle, and rear.

Quick and Easy Field Disassembly
Disassemble, clean, and maintain your firearm easily and quickly. The field disassembly does not release small, easily lost parts or spring mechanisms. You can perform the disassembly completely without tools.
We believe that when a firearm is easy to disassemble and maintain, maintenance will be performed more frequently, thus extending the lifespan of both the firearm and the barrel.
