Anarchy Outdoors Grip Penguin Precision Rifle Right Hand Black APRG-RH-B. Methodicallydeveloped over the last several years by a former 3rd Ranger Battalion special operations soldier with help by several individual Federal Law Enforcement Agents our unique grip was designed to give Precision Rifle Competitors an edge with quick repeatable and ergonomic action on the gun. The Penguin's design allows for true thumb rest positioning while allowing the index finger to be placed lower and directly in-line with the trigger. This development was critical in reducing shooter fatigue when behind the gun for long periods of time. The palm swell allows for greater control and manipulation of the firearm while the palm shelf allows the shooter to rest their hand to transition instantly if the need arises.
