Otter Creek Infinity 556K Elite

The Otter Creek Labs Infinity 556K takes the proven DNA of the full-size Infinity 762 and packs it into a shorter, lighter 5.56 can built for hard-use rifles. It runs across AR-15s, AK hosts, bolt guns, and SBRs without turning your rifle into a brick or causing reliability issues, and the swappable end cap system means you can tune the backpressure instead of living with the factory default.
