Interesting, recoil mitigation is not directly part of the design of this rifle. It's a component, but the patents on the rifle cover the barrel quick change system, the recoil component is a separate patent.
This system does not limit recoil, per se. It limits FELT recoil. Specifically, it's trying to reduce the impact of the bolt carrier with the backstop of the receiver, which delivers a sharper impulse to the shooter. The recoil is still there in the system.
This is in contrast to things like muzzle breaks and compensators which use the cartridge gas, essentially, as "rockets" to reduce felt recoil and control muzzle rise.
