Slide-in Grip insert to remove the "Skeleton" look. Includes a slot for a nested hex nut and a sling attachment point.
Gripstrike version adds an upsidedown N-Strike stock attachment point so that you can add a stock to either the Talon Claw or ESPER.
Note: The "Ayy LMAO" Insert ONLY works with Slug's alternate matching "Ayy LMAO" Caliburn grip. It does not fit into the standard grip.
