    Comfortable and well-built

    The cheek weld feels natural and consistent, especially during longer range sessions. Length-of-pull adjustment is quick and positive. Overall quality is exactly what you’d expect from a solid AR stock.

    Perfect fit on my AR platform

    Dropped right onto my mil-spec receiver extension with no issues. Tight lockup and no noise when moving. Excellent option for a duty or training rifle.
