What better way to train LE, military and security personnel that use the AR15/M16 M4 carbine, than with a REAL M4 carbine in 22 LR? The K22-M4 is the same size, weight, shape, and fell as the 5.56 version of the same rifle. As a matter of fact, after a day of training with the 22LR upper, officers can switch it back to 5.56 in seconds! Also, consider having the K22M4 assembled just the way the duty M4 is configured, or for that matter, order the K22-M4 with the 5.56 upper at the same time to create what Olympic Arms calls the "Tactical Pack."
The K22-M4 features a 16-inch button rifled match-grade SS barrel, threaded muzzle, collapsible M4 stock, and choice of Picatinny flat-top or A2 upper (shown with A2). This cool carbine ships with an OD Green hard case, sling, and hi-capacity Black Dog magazine. Remember, this is a REAL AR15 chambered in 22LR, not just a look-alike.
