Santan Stt-15 5.56 10.5" 30-Round Carbine

The San Tan Tactical STT-15 5.56 NATO 10.5" semi-automatic rifle in black anodized finish delivers a purpose-built platform for operators requiring a compact, maneuverable carbine without a stabilizing brace. Chambered in 5.56 NATO with a 30-round capacity, this short-barrel rifle balances portability with the ballistic advantages of America's standard intermediate cartridge, making it suitable for close-quarters environments where full-length ARs prove unwieldy.

The 10.5-inch barrel length reduces overall length while maintaining adequate velocity for 5.56mm projectiles in practical engagement distances. At 9.44 pounds, the STT-15 sits at a manageable carry weight during extended operations. The anodized black finish provides corrosion resistance suitable for field environments. The rifle ships configured as a bare receiver platform without a brace, allowing end-users to configure the rear assembly according to their jurisdiction's regulatory requirements and personal ergonomic preferences.

This configuration appeals to law enforcement tactical units, military personnel, and civilian operators who require a compact 5.56 platform for home defense, patrol duty, or precision rifle training in confined spaces. The 30-round magazine capacity aligns with standard AR-pattern ammunition supply chains. San Tan Tactical's STT-15 line has established itself as a reliable short-barrel rifle option for shooters prioritizing modularity and legal compliance over integrated brace systems.

Whether selected for duty use or civilian ownership, the STT-15 5.56 10.5" carbine offers the ergonomic and ballistic foundation of the AR-platform in a footprint suited to tight workspace, vehicle storage, or close-target engagement scenarios where velocity and capacity matter equally.
