Exile Machine’s 3d printed AR15 Grip California compliant featureless SideGrip replaces the standard grip on your AR. When used properly it may help you keep legal in restricted jurisdictions.
A CA-Featureless configuration has none of the features listed by law. Features that must be removed include pistol or forward grip, flash hider, grenade launcher, collapsible, folding or thumbhole stock. With a featureless configuration no magazine lock (aka bullet button) is required and you can use your legally-owned or legally-borrowed large capacity feeding devices. Consult a competent attorney before attempting to build compliant to the laws of any restrictive state.
In operation the trigger hand is situated entirely on one side of the grip. The dorsal fin prevents your thumb from wrapping around the grip. Integral thumb rest aids in control and handling.
Based on a standard grip design distributed by DEFCAD
