The MTs-566 precision / sniper rifle is a newest development of the Central Bureau for Sporting and Hunting Arms (TSKIB SOO), located in the city of Tula. This rifle is officially certified in Russia as a hunting weapon, and will be available for sale on civilian market in 2020. It is based on an experimental OTs-129 semi-automatic sniper rifle, designed by the same organization. MTs-566 rifle is intended to compete with several domestically available precision hunting / sporting semi-automatic rifles chambered for .308 win ammunition. Those include Kalashnikov MR1 rifle, ORSIS K-15 Brat. It will also compete with more expensive foreign weapons of the similar class. As advertised, initial version of the MTs-566 rifle will be available in only one configuration, with 60 cm / 24” barrel and chambered for .308 Win. However, due to modular nature of the gun other chamberings and barrel lengths might be available in the future. With proper ammunition MTs-566 rifle is intended to deliver 1 MOA or better accuracy.
The MTs-566 precision / sniper rifle is gas operated weapon. It uses short stroke gas piston, located above the barrel, and gas block features manual gas regulator with two settings. Barrel is locked using rotating bolt with six radial lugs. Monolithic receiver is made from aluminum alloy, with steel insert inside where barrel is held by several screws. As such, barrel can be removed from the gun for maintenance, inspection or replacement. Magazine housing is also bolted to the receiver and can be replaced, at least theoretically, for change of caliber. Rifle uses striker-firing system, with non-adjustable trigger. Safety levers are ambidextrous, and are located behind and slightly above the trigger on either side of the gun. Magazine release buttons also are ambidextrous. As offered, MTs-566 rifle uses AR-10 compatible Magpul PMAG-308 magazines, and features bolt hold-open device. Rifle is intended for use with optics, and features long Picatinny rails, integrated into the receiver. However, as a heritage of its military parent, it also features integrated iron sights on folding bases. Front sight base is attached to the gas block and folds forward. Rear sight base, with FG-42 / OTs-03 style diopter sight, folds to the rear and down, and when not in use, it is concealed in “upside down” position in a cavity inside the stock hinge. In standard configuration, MTs-566 is offered with proprietary shoulder stock, which can be folded to the right to save space. The stock hinge has an AR-15 compatible thread at the rear, so the standard stock can be replaced with almost any commercially available AR-15 style tube and stock. In its standard configuration, MTs-566 rifle is offered with so called “closed type” flash moderator, which is an empty can, which is screwed onto and over the muzzle part of the barrel. It looks like a sound suppressor (which it technically is not, at least per Russian regulations). Muzzle end of the barrel is provided with standard threads, so instead of this “can” user can mount various flash hiders, muzzle brakes and other devices of his choice.
