The Snowflake series lower showcases Spike's Tactical's unique rollmarks: a unicorn graphic with "SNOWFLAKE," "CAL–MULTI," and "MOD–ST15," plus themed selector legends "TRIGGERED" and "SAFE SPACE" with third-position text. The right-side lower is marked "SPIKE'S TACTICAL, APOPKA, FL, U.S.A." This variant was introduced circa 2017 and has become one of the brand's most recognizable configurations.
Chambered in 5.56mm NATO, this AR-15 uses a semi-automatic, direct-impingement system with a low-profile gas block hidden under a long free-float M-LOK handguard. The approximately 16-inch barrel terminates in an A2-pattern flash hider secured with a crush washer, and the threaded muzzle offers standard compatibility with common devices.
The upper receiver includes a forward assist, shell deflector, and ejection-port cover, along with a T-marked Picatinny top rail (forging code "A"). The free-float aluminum handguard is a slick-top M-LOK design (no integral 12 o’clock Picatinny); a short add-on M-LOK 1913 rail section is installed near the muzzle for the front sight, while ample M-LOK slots provide mounting flexibility and help keep weight forward in check.
Ergonomics are enhanced with FDE Magpul furniture: a collapsible carbine stock with adjustable length of pull and a matching Magpul pistol grip. An aftermarket trigger is installed for a refined fire-control feel, and a B.A.D.-style bolt-catch extension lever speeds lock-back and release. Flip-up polymer sights are already mounted for immediate use.
The receiver set is aluminum with a matte black anodized finish. Capacity is stated at 30+1 with detachable box magazines, and this rifle includes a Magpul PMAG GEN M3 windowed 30-round magazine. Made in the USA.
