The cost is determined by the amount of time/difficulty of the work as well as the amount of coverage of the engraving on the gun. I do not charge extra for a custom design as I prefer to make each one unique. The price is subject to change as time goes on but right now the price for custom checkering (Fish scale/Basket weave) as well as a design on the stock will start at $600. The price can go up for additional engravings on the cheek plate or for full coverage on a single stock. The guns on my site are currently $600 - $800 engravings. Engravings on pistol grips normally range between $100 - $250 from light to heavy coverage. I ask for at least 6 weeks for a gun, and prefer if the gun is taken apart and only the stocks or grips are mailed to me.
