HOW TO MEASURE FOR CUSTOM LEATHER BUTT COVERS:

Please follow these steps to measure for the stock cover:
1. Measure the circumference of the base of the stock.
2. Four inches down from the base, measure the circumference again.
3. Six inches down from the base, measure the circumference again.
4. Trace around the base of the stock.
5. Measure the widest point of the width from both the top and bottom, as well as from side to side.
6. Along with these measurements, please provide a description of the stock, including the model of the firearm and the profile of the butt plate area (e.g., curved, flat, pad type).
7. Let us know if you have any color preferences.
8. Inform us if you would like the leather to be rough end out (standard for grip) or smooth at the butt end.
9. If possible, please send us a picture along with your request to: willshootem@pioneergunworks.com.

10. Double check those measurements! Yep.. that’s 4 7/8” not 5 7/8”!!
