This marksman kit from UMAREX not only comes with the XGB .177 caliber air pistol, it also includes a carbine kit to completely transform the XGB into a more versatile training rifle. The XGB air pistol is constructed from a durable polymer frame and slide to keep this pistol lightweight and easily manageable during long training sessions. Securly lock the XBG into place within the carbine kit to extend the barrel length and provide a more ergonomic way to operate this air pistol. This carbine kit features a removable polymer vertical grip and stock that can both be folded against the carbine when not in use for easier transportation. The stock and foregrip provide a sturdy and comfortable platform when taking aim down range, and help greatly in keeping the rifle stable during operation. Picatinny rails along the top of the carbine and all four sides handguard allow for the addition of a wide range of tactical accessories including dot sights, flash lights, or lasers. A fixed front sight and an adjustable rear sight assist users in quickly and accurately zeroing in their targets on the fly without the need for an additional optic accessory. This pistol & carbine combo is powered by a single 12g Co2 cartridge, which is housed within the polymer pistol grip.
