The operating system is a short-stroke gas piston with a rotating bolt and a three-position gas regulator (0/1/2), giving the shooter adjustable settings for varied ammunition or conditions. The non-reciprocating charging handle is reversible and can be used as a forward assist, and a left-side bolt catch is positioned inside the trigger guard for rapid manipulation. An ambidextrous safety supports bilateral control.
The 11-inch barrel is threaded 1/2x28 and cut with a 1:7 twist. It is paired with an aluminum M-LOK handguard and a continuous MIL-STD-1913 Picatinny top rail extending across the receiver and handguard. Factory folding sights include a front post with a luminescent dot and a windage-adjustable rear diopter aperture.
Construction combines a 7075-T6 aluminum upper receiver with a polymer lower for durability and weight savings. The pistol accepts STANAG/AR-15 magazines and uses a standard magazine release. The rear receiver endcap is threaded 1-3/16x16 UN for AR-15 buffer-tube accessories. Factory overall length is about 22.8 inches, and weight is about 5.6 lb.
Proof and origin details include CIP proof marks with a 2021 date and a CZ USA, Kansas City, KS import mark. Matching serial numbers on the receiver and barrel trunnion add desirable continuity for buyers who value documented components.
