TheUmarex 850 M2 XT Kit 4.5 mm with compensator is a modernized version of the popular 850 model, equipped with a flask with adjustable cheek-piece, a capacious 8-shot magazine, an externally threaded barrel and a set of accessories in the form of a compensator, a bipod and an optical sight.
The Umarex 850 M2 XT 4.5mm is a modern designed carbine distinguished by high precision, high initial velocity and high operating culture.
The carbine's stock is made of solid polymer, which is additionally reinforced with fiberglass. The stock and pistol grip have aesthetically pleasing fluting to improve grip, and comfort.
The buttstock has a symmetrical cheekpiece with adjustable height (removable cap) and a vented rubber foot that provides a stable point of support.
After the upgrade, 3 Picatinny rails were installed on the bed, for mounting shooting accessories such as a TMB 2 bipod (included) or a flashlight.
The Umarex 850 M2 XT 4.5mm is powered by an 88gCO2 capsule, which allows the user to fire approximately 220 shots. Thanks to the use of an aluminum magazine with a capacity of 8 shotgun shells and a 4-barrel lock, the airgun is characterized by high rate of fire and very comfortable operation.
When reloading, an automatic safety is activated, which must be turned off each time before firing. The carbine has a threaded barrel with a length of 600 mm, thanks to which we can get a repeatable focus already after a short training.
The barrel's outlet is terminated with a 1/2" UNF male thread, which allows the installation of the included compensator. The chambered design and proper arrangement of the holes ensure efficient gas evacuation, which reduces recoil and improves accuracy.
The carbine shoots diabolo shot in 4.5 mm caliber, which reaches an initial velocity of 250 m/s.
The Umarex 850 M2 XT 4.5 mm air rifle has a two-stage trigger mechanism with tactile operation and medium resistance. The carbine is equipped with fiber-optic sighting instruments: a tunnel-shaped bow-tie and a vertically and horizontally adjustable sights.
The fiber optics, with a contrasting (green-red) color scheme, make it much easier to align the bowtie and the pincer, and also absorb ambient light, thus enabling shooting in low or residual light, such as after dark.
In addition to the adjustable bipod and suppressor, the kit also comes with a Walther 6 × 42 optical sight mounted on a standard 11mm rail.
The Umarex 850 M2 XT 4.5mm is a very accurate, efficient and comfortable to use carbine, designed for recreational shooting.
