Cartridge flexibility and use cases

6.8 Hybrid barrel

The 6.8 Hybrid barrel offers a modern balance of higher terminal energy and flatter trajectory compared with traditional intermediate rounds. It’s well-suited for hunters pursuing medium game and for operators wanting enhanced barrier performance without a radically different recoil impulse. For shooters seeking extended effective range in a compact package, the 6.8 option is compelling.

7.62 NATO 16″ barrel

The 7.62 NATO 16″ barrel provides proven stopping power and long-range capability with common, battle-tested ammunition. Its heavier projectile and established terminal characteristics make it a solid choice for precision-oriented roles or scenarios where penetration and retained energy are priorities.

Note: the listing specifies one small blemish on the side of the uninstalled barrel assembly; cosmetically minor, it does not affect function but is disclosed for transparency.
