The Echo AR-II binary trigger is a centerpiece of this build, offering Safe, Semi, and Echo positions that fire on both pull and release. It features a gold-tone curved trigger shoe and works with the ambidextrous safety selector for familiar, AR-based controls.
The pistol uses a direct-impingement gas system and retains standard AR-15 features, including a forward assist, ejection-port cover, and brass deflector. It accepts STANAG-pattern detachable magazines and has a listed capacity of 30+1.
Up front, a FosTecH-branded free-float M-LOK handguard features M-LOK slots along most of the 12 o’clock with short Picatinny sections for the BUIS, providing mounting space, and is marked USA. Flip-up front and rear sights are installed as back-up iron sights.
Ergonomics include a stabilizing brace made of polymer with a hook-and-loop strap and a textured polymer pistol grip. The ambidextrous selector supports versatile handling.
Optics are covered by the included Sig Sauer Romeo5 red-dot sight with a red dot reticle, complementing the BUIS. The package is rounded out by seven 30-round magazines, including five Amend2 polymer magazines, one Magpul PMAG, and one translucent polymer 30-round magazine of another brand.
