Crosman 13xx Target Grips

Cut down from the Mk.2 buttstock and given just a bit of palm swell. Will help stabilize aim with one or both hands and compliments the accompanying Pump Arm fairly well.

This is an ambidextrous model, though one may forego or install the thumb shelf on either side. The thumb shelf is designed more for a two-handed grip, with the dominant thumb atop the other. Bed the top with some flexible adhesive or RTV to reduce vibration/noise from the hammer.
