It is built around aluminum alloy receiver, which is possible due to bolt locking directly to the barrel extension. Precision made barrel is free floated and equipped with muzzle brake and/or optional sound suppressor (silencer). Rifle is offered in several configurations, with various barrel lengths and optional extended Picatinny rails. Rifle is fed from detachable box magazines with 5-round capacity. Side-folding shoulder stock can be easily adjusted to user preferences, and is fitted with adjustable, folding rear support leg. Folding adjustable bipod is attached to the forend, and rifle can be fired either from ground or other support (for maximum accuracy) or off the shoulder (in emergency situations). Sighting means are provided by telescope or night sights, installed by the user onto integral Picatinny rail, runnig at the top of the receiver. Additional accessory rails are provided on both sides of the receiver.
