The 11.5 inch barrel is chrome-moly-vanadium steel, chambered in 5.56x45 NATO, and threaded with an A2-pattern flash suppressor. It runs a direct impingement gas system with a low-profile gas block for reliable cycling in a compact format.
The Aero Precision ATLAS R-ONE free-float handguard is aluminum with M-LOK slots and a continuous 12 o'clock Picatinny rail. This setup keeps weight down while offering solid mounting real estate along the top rail.
Controls are well-sorted, including an ambidextrous extended charging handle, a manual safety selector with pictogram icons, and a standard magazine release. The upper receiver includes a forward assist and ejection-port cover.
The SB Tactical adjustable pistol stabilizing brace has an integral QD socket and a Velcro strap, and pairs with a textured polymer pistol grip for secure handling. The two-tone finish features an earth-tone lower and a black upper/handguard.
The included SIG SAUER ROMEO5 red dot is mounted on a Picatinny riser, providing a red dot aiming solution that is already installed and aligned to the top rail.
