Umarex Unleashed – M4 OPS Semi Automatic Carbine

Carl Walther Germany, through a license agreement with New Colt Holding Corp., unveils the Colt Tactical Rimfire semi-automatic rifle in .22 LR and is importing them through Umarex USA. Teaming with aesthetic appeal, Walther creates a weapon that has the look and feel of a standard 5.56×45 NATO M4. This weapon has a full-length Picatinny quad-rail system for mounting endless accessories such as the Umarex Colt .22 Tactical Rimfire Folding Rear Sight or the Umarex Colt .22 Tactical Rimfire Carry Handle.

The Details

A flat top receiver and 16.2-inch barrel allow for easy maneuverability. The adjustable telestock, mounted on the back of the weapon, allows the firearm to fit any shooter’s style. The aluminum barrel sleeve is CNC-machined and anodized for a finishing touch. The barrel twist is 1 in 13-3/4 inches with six rifling grooves. Unlike a traditional AR-15, this firearm uses a blowback operation instead of a direct gas impingement.

The slide, held to the rear by an internal slide catch that activates when the magazine follower extension pushes upward when the last shot fires, allows for fast tactical reloading.

The front and rear sights are adjustable for elevation and the rear sight is also adjustable for windage.

You can adjust the bolt speed for your particular ammunition type by simply turning a screw with the provided Allen wrench. To access this screw, merely disengage the charging handle and tilt the upper receiver forward. This will present the screw just below the charging handle. This position is ideal for cleaning the weapon as Walther recommends that you not take down the firearm any further.

The magazine release is easy to reach and is located just above the trigger guard on the right side of the lower receiver just below the dust cover. The safety, located just above the pistol grip on the left side of the lower receiver, rotates forward and backwards at a somewhat odd 180 degrees.

During our testing, using Aguila, Armscor, and Federal bulk ammunition, the weapon cycled 100% of the time with no jamming issues. The 10- round magazine was a bit cumbersome due to its relatively low capacity. The single-stage trigger has a pull of 6 pounds, 9 ounces.

Included accessories are:

  • A wrench for removing the muzzle break
  • An Allen wrench for the bolt speed adjustment screw
  • An owner’s manual

The Downside

Although the look and feel of the Tactical Colt M4 is very close to a traditional AR-15, some minor differences are present. The bolt stop paddle is present but not functional, as well as the forward assist located just to the right of the charging handle.

True Value

The value of this firearm lies in its appearance and low cost of ammunition associated with the .22 LR. Perfect for plinking, the Colt .22 Tactical Rimfire is an excellent choice for any shooter who wants a rifle that is both fun to shoot and great to look at.
