Armaspec St45 45 Degree Short - Throw Ambi Safety Selectr Blue

The Armaspec ST45 45 Degree Short-Throw Ambi Safety Selector in Blue is a precision-engineered ambidextrous control designed for AR-15 and AR-10 platform shooters who demand faster, more intuitive manual-of-arms without sacrificing ergonomic symmetry. This selector addresses a fundamental limitation in standard safety levers: the acute 45-degree throw angle dramatically reduces the time and hand movement required to transition between safe and fire modes, making it ideal for tactical applications, competitive shooting, and high-round-count training scenarios where every fraction of a second counts.

The short-throw design minimizes the mechanical arc your thumb must travel to disengage the safety, reducing fatigue during extended shooting sessions and enabling faster target engagement under pressure. The ambidextrous configuration allows both left- and right-handed shooters to operate the safety naturally from either side of the lower receiver without repositioning grip or hand angle—a critical advantage for shooters who transition between different platforms or train in dynamic scenarios. The blue finish provides a professional aesthetic while offering subtle visual contrast against anodized aluminum receiver surfaces, and the robust construction ensures reliable operation across thousands of cycles without wear or play development.

Installation is straightforward on any standard AR-15 or AR-10 lower receiver—no gunsmithing required. The selector drops into the existing pivot hole and requires only a standard roll pin, making it an accessible upgrade for builders and field-serviceable on established rifles. Competitive shooters, law enforcement trainers, and civilian operators running modern tactical carbines benefit most from the reduced safety manipulation time, while left-handed shooters particularly appreciate the true ambidextrous lever that eliminates the awkward thumb-stretch compromises of right-hand-only safeties. Weight remains negligible at 0.1 lbs, adding no measurable mass to your platform.
