The MA-15 lower is marked "MATRIX AEROSPACE CORP., CLAREMONT, NH USA," "MODEL MA-15," and "CAL – MULTI." The selector shows SAFE in white and FIRE in red. The platform uses a direct-impingement gas system and standard magazine release, and it feeds from STANAG-pattern magazines.
Its 7.5-inch threaded barrel pairs with a stainless multi-ported muzzle brake/compensator to manage muzzle rise. Chambered in 5.56mm NATO, this AR pistol carries a 30+1 capacity and includes a 30-round Magpul PMAG.
The slick-side upper (no forward assist) includes a brass deflector and ejection-port cover. A continuous 1913 top rail connects to an aluminum quad-rail handguard with 12/3/6/9 o'clock rails and an L26 side index marking, providing ample mounting space. Low-profile flip-up front and rear sights are installed.
Furniture is set up for control and stability with a SIGTac stabilizing brace and strap on a pistol buffer tube featuring a knurled section and a single-point sling loop end plate. A textured, finger-groove polymer/rubberized pistol grip and a PTK-marked angled foregrip round out the handling features.
Custom engraving elements distinguish this example: the ejection-port cover bears "Acta non Verba," and the interior receiver surface includes a Psalm 23:4 engraving. The receivers are aluminum with a matte black anodized finish for a uniform, durable appearance.
