About
What it is, and why it matters
The M4-WAC-47 is a select-fire assault rifle chambered in 7.62x39mm, produced by Ukrainian Armament Research and Design since 2017. Featuring a 30-round magazine capacity, this assault rifle offers generous firepower for duty use and home defense. The 14.5-inch barrel maximizes accuracy potential and ballistic performance, making this an excellent choice for target shooting, competition, or field use. At 3600g (127.0 oz), this is a substantial firearm whose weight contributes to reduced felt recoil and enhanced stability during precision shooting. The aluminum alloy frame achieves a notable weight reduction compared to all-steel construction while maintaining the structural rigidity required for safe, reliable operation. Safety features include ambidextrous safety selector, firing pin block, reflecting modern design standards that prioritize safe handling and operation. This firearm represents its manufacturer's commitment to delivering a well-engineered, reliable product that serves the needs of discerning shooters seeking quality, accuracy, and dependable performance from a proven platform. As a recognized participant in the global firearms industry, Ukrainian Armament Research and Design applies modern manufacturing technology and quality control processes to deliver products that compete effectively in a market where reliability and performance are non-negotiable requirements for both civilian and professional end users.
The M4-WAC-47 was widely described as a 'strong political message to Russia' when unveiled - the Ukrainian military's adoption of an American-pattern rifle design, even one chambered in Soviet calibers, symbolized Ukraine's geopolitical pivot toward NATO and the West. The Kyiv Post notably characterized the rifle as representing Ukraine's aspirations for NATO membership through its small arms choices.
The M4-WAC-47 is designed to be convertible between 7.62x39mm, 5.45x39mm, and 5.56x45mm NATO by swapping the complete upper receiver, bolt group, and magazines. The rifle was first delivered to Ukrainian troops for evaluation in January 2018. Military Factory lists the barrel length as 675mm (26.57 inches), which appears to be erroneous and likely represents overall barrel assembly or a data entry error - all other sources and photographs confirm a standard M4-length 14.5-inch (368mm) barrel consistent with the carbine designation. The muzzle velocity of approximately 680 m/s for the 7.62x39mm cartridge from the shorter 368mm barrel is reduced compared to the standard 715 m/s from a 415mm AKM barrel. The rifle was conceived as a 'bridge solution' between Ukraine's aging Soviet-era Kalashnikov inventory and eventual full NATO standardization.
