The One Horse OH-15 Complete Rifle is a semi-auto .223 Remington/5.56 NATO carbine from One Horse (brand part no. OH-OG01), built as a fully assembled, ready-to-shoot rifle rather than a stripped lower or parts kit. It pairs a 16-inch barrel with a 1:8-inch twist rate suited to a wide range of 5.56 bullet weights, and it ships complete with Magpul-pattern furniture in black for a rifle that’s ready to run straight out of the case. A 30-round magazine is included, so there’s no need to buy one separately before the first range trip. This is a straightforward, no-frills AR-pattern rifle built for range time, home defense or as a dependable first modern sporting rifle.
