PROBLEM STATEMENT
USSOCOM is seeking a carbine system to act as a replacement or upgrade for the current URG-I (Upper Receiver Group - Improved). The goal is to integrate advancements in material science and weapon design to provide operators with a technically superior individual weapon system capable of firing both legacy 5.56x45mm NATO and emerging hyper velocity ammunition.
The current URG-I is an M4-based platform optimized for standard 5.56NATO ammunition, with a recognized effective range of approximately 300 meters. Special Operations Forces (SOF) require the ability to provide effective fire on targets with their primary 5.56mm carbine out to 600 meters and beyond. This weapon system will allow an operator to effectively engage targets at extended distances while maintaining the portability and ergonomics of a lightweight carbine.
The Hypervelocity Improved Carbine (HICAR) program will develop an improved carbine capable of operating with currently issued 5.56NATO ammunition, while also incorporating design features that ensure reliability, durability, and longevity with the use of future hypervelocity 5.56x45mm ammunition. The ability to leverage the performance benefits of current and future experimental hypervelocity rounds is vital to addressing future capability gaps on the battlefield.
Weapon submissions that address the following technology priorities will benefit during the selection process:
Hypervelocity Ammunition Compatibility: The ability to accept and reliably cycle both 5.56NATO and hyper velocity 5.56x45mm ammunition is a primary objective. The...
