ORSIS has first introduced their semi-auto rifle about a year ago during MILEX-2017 arms exhibition in Belarus. Recently, they have released it to the Russian civilian market. The Russian designation of the rifle is ORSIS-K15 “Брат”. The word “Брат” means “brother”, but they probably decided to make it sound cooler in English naming the rifle ORSIS-K15 “Bro”.
ORSIS-K15 is a gas operated semi-auto rifle chambered in .308 Winchester. The lockup of the action is accomplished by a 2-lug rotating bolt. The rifle is offered either with 16″ or 20″ barrel options. The overall length is 1,208mm (about 47.5″). It is not specified with which barrel length it has the mentioned overall length. The rifle weighs 4.6 kilograms (10 lbs 2 oz) with an empty magazine and without the scope. It is optimized to work with Magpul magazines.
Other features of the ORSIS-K15 rifle are the ambidextrous charging handle and safety selector, monolithic top Picatinny rail and adjustable two-position gas block. It is also possible to order an ambidextrous magazine release button. The rifle takes an AR-15 buffer tube which allows to equip it with any AR-15 stock. The company also states that the muzzle thread pitch is compatible with AR rifles. I assume it is a 5/8×24 pitch.
ORSIS-K15 “Bro” rifle has an introductory price of 200,000 rubles (about $3,560).
Reportedly, the designer of this rifle is Vladimir Zlobin, who is known for designing the original AK-12, VSSK “Vychlop” rifle and several other firearms.
