Made exclusively for PSE archery, the Competition limbs are an ILF (International Limb Fit) style limb. Constructed with laminated multi-wood core and fiberglass face and back, the Competition limbs are our mid-range ILF limb and will fit the X-Appeal and Summit risers. Smooth shooting and reliable, the PSE Competition limbs are a great choice for the intermediate shooter. Limb weight and lengths are based on a 25 inch riser. Add 2 pounds and subtract 2 inches for a 23 inch riser bow.
