"Baby (Masculine)"),[3] sometimes referred to as the Vulcan-M,[4] is an assault rifle developed by the Ukrainian arms company Interproinvest (IPI).

[6] The development was based on a contract placed by the Security Service of Ukraine with prototype rifles provided before inquiries were made by the Ukrainian Ministry of Defence in 2008.

[14] On February 27, 2022, an alleged saboteur was arrested in Odesa by the State Border Guard Service and the National Police of Ukraine in a joint operation.

Among the items confiscated included a loaded Malyuk rifle with a Makarov PM, an RPG-22 and two T-62M anti-tank mines.

[6] This allows spent cartridge cases to fall alternatively between 45 degrees or downward while reduced gas is sent to the receiver.

[6] Recoil is reduced by 50% and the design allows the user to fire the rifle, unload and load the magazine with one hand.

[5] A commercial version of the Malyuk was developed at the Krasyliv Assembly Manufacturing Plant in cooperation with Electron Corporation.
