The 16" barrel is made from 4150 CMV steel and is factory threaded, capped with an A2-pattern flash hider. Barrel markings include "5.56 NAT" and "CrMoV," and the rifle uses a 1:8 twist for 5.56mm NATO.
The rifle runs a mid-length gas system with direct impingement operation. Aluminum receivers wear a matte black finish and include a forward assist, brass deflector, and ejection-port cover. The upper receiver shows an "A" forging mark, and the lower is roll-marked "IWI US, INC / MIDDLETOWN, PA."
An aluminum free-float M-LOK handguard with a continuous top rail and IWI logo provides a rigid, modern interface. The configuration keeps weight forward of the receiver and offers ample mounting real estate along the handguard.
B5 Systems furniture includes a 6-position collapsible stock with an integrated QD socket and a matching B5 pistol grip. The rifle has a manual safety and a 30+1 capacity. A windowed Magpul PMAG Gen M3 and an installed M-LOK QD sling-swivel mount are included.
