Great product, works awesome for what it is on 9mm - Griffin Armament EZ-LOK Comp

This is a micro comp, it's not gonna give the most compensation, but it definitely helped my grouping. It's definitely a perfect helpful thread protector for the ez-lok barrel adapter. Use this for compensating when you're not attaching your silencer with ez-lok piston or ez-lock direct thread adapter. It's recommended to apply 2.5ft/lbs of torque onto the adapter, it's perfect, i tighten every 50 rounds as manuf. suggested but it never needs it, it stays tight. It's a MUST for ez-lok/camlok adapters.
