Michael with @olympusarmsofficial tells us about their long recoil 308.
The Vulcan rifle is a long-recoil, multi-caliber, recoilless and modular firearm that can be configured in a variety of different ways. It is currently chambered in .308 Win/7.62x51mm, but can be easily converted to fire other calibers with a 60-second, no-tool barrel change. Current features include: Full ambidextrous fire controls, a non-reciprocating forward charging handle, an adjustable muzzle brake for different firing rates, and full compatibility with AR-10 components, such as stocks and grips.
