Built on a stamped AK-pattern receiver with riveted trunnions, this Beryl M1 uses a semi-automatic, gas-operated, long-stroke piston system with a rotating bolt. The receiver features an enlarged safety/selector shelf for confident manipulation. It is chambered in 5.56x45mm NATO and accepts detachable Beryl-pattern 5.56 magazines, delivering a 30+1 capacity.
The barrel is 18 inches and threaded 1/2x28, with an installed cylindrical multi-port muzzle brake. An AK-style front sight base with protective ears and a bayonet lug anchors the front end. The finish presents in black across the stamped-steel receiver and components, while the installed muzzle brake is silver/in-the-white.
Topside, the Beryl-pattern railed top-cover provides a Picatinny rail and integrates a tangent-style adjustable rear sight; the sight assembly interrupts the 12 o'clock rail, so it is not continuous with the forward handguard rail. Up front, the aluminum handguard includes 12, 3, 6, and 9 o'clock Picatinny rail sections with lightening holes, and a vertical foregrip is already installed at 6 o'clock.
Furniture includes a telescoping, adjustable stock with a ribbed rubber buttpad and an approximate length-of-pull range of 11–13.5 inches, plus a polymer pistol grip with finger grooves. Markings include ".223 S Beryl M1 cal. 5,56x45mm [B223]" on the receiver, "RADOM POLAND Fabryka Broni – Łucznik," the FB Radom triangular logo, "ARMS OF AMERICA LLC ROCKWALL TX" import mark, "cal. 5,56mm" on the trunnion, "5.56" on the gas system, and a Polish eagle crest on the upper handguard/rail block.
