The Kaliber Tech KT10 Longbow presents itself as a semi-automatic rifle engineered for precision applications in both target shooting and hunting scenarios. It is chambered in 6.5 Precision Rifle Cartridge (PRC) and .300 Winchester Short Magnum (WSM), two cartridges often associated with magnum performance. A distinguishing characteristic of the KT10 Longbow is its gas-operated mechanism and this sets it apart from many rifles in these calibers that have traditionally utilized bolt-action designs. This configuration offers an alternative to manual cycling of the action between shots.
Another element of the KT10 Longbow is its compatibility with Accuracy International Chassis System (AICS) pattern magazines. This feature allows for the use of cartridges with a greater overall length (COAL), specifically up to 2.955 inches. The ability to accommodate longer cartridge overall lengths can be relevant for shooters who handload ammunition or utilize factory loads with extended bullets, potentially contributing to consistent performance, particularly in long-range shooting disciplines.
The rifle's architecture is based on the DPMS-pattern AR platform, with the lower receiver being an in-house design by Kaliber Tech, a common practice in the AR-style rifle market where manufacturers often customize components within established platform patterns.

The KT10 Longbow is offered in two distinct configurations to address varying user preferences. The standard model incorporates a Magpul MOE grip, a Magpul PRS Gen3 stock, and a 15-inch free-floating M-LOK handguard. Conversely, a carbon fiber variant is available, which integrates lightweight materials into its construction. This results in a weight difference between the two models: the standard version weighs approximately 10 pounds, 8 ounces, while the carbon fiber model weighs approximately 7 pounds, 10 ounces, offering a more portable option.

Shared specifications across both configurations include a 22-inch barrel equipped with a three-port muzzle brake. The rifle features a +2 rifle-length gas system, which indicates an extended gas tube length, and an adjustable gas block, allowing for tuning of the gas system to different ammunition types or suppression devices. Both models incorporate a dual ejector bolt, which can contribute to reliable spent casing ejection. The barrel twist rates are optimized for the respective calibers: 1:8 inches for the 6.5 PRC and 1:10 inches for the .300 WSM. The overall length of the rifle is stated as 43.5 inches.

Kaliber Tech provides various individual components and assemblies for customization, including upper receiver assemblies, stripped lower receivers, bolt carrier groups, and builder kits. These rifles are built to order, with a lead time typically ranging from 7 to 10 weeks from the time of order. A deposit of $2,000 is required to initiate the build, with the remaining balance due upon completion. The manufacturer's suggested retail price for the standard KT10 Longbow is $4,219, while the carbon fiber variant is priced at $5,099.

The KT10 Longbow is positioned by its manufacturer as the first commercially available semi-automatic rifle chambered in both 6.5 PRC and .300 WSM. This dual chambering in a gas-operated platform represents a development in the market for these specific magnum cartridges, which have seen increasing adoption in long-range shooting and hunting. The combination of precision-oriented features, magnum cartridge compatibility, and semi-automatic operation is presented as a versatile offering.
