One Horse OH-15 AR Pistol with KAK Brace

Whether configured for maximum maneuverability in tight spaces or enhanced ballistic performance and suppressor use, every OH-15 AR pistol is engineered around reliability, smooth cycling, and practical functionality. From home defense and range training to vehicle setups and tactical applications, these pistols are designed to perform under demanding conditions without unnecessary weight or complication.

Each model features durable American-made construction, precision-machined components, a carbine-length gas system, free-float M-LOK handguard, Mil-Spec buffer tube, and a KAK Brace for improved control and stability. The .300 Blackout variants excel in short-barrel and suppressed configurations, while the 5.56 NATO models provide fast handling, affordability, and proven defensive capability.

This is a platform built around purpose—not gimmicks. Compact enough to maneuver easily. Reliable enough to trust. Versatile enough to adapt.

Compact. Capable. Ready.

Range. Home. Tactical.

One AR pistol platform built to run.

Proudly made in the USA.
