PISTOL FLUSH AND CROWN SERVICE from Suarez International near Prescott, Prescott Valley, AZ

This is a service where we cut the end of your barrel flush with the face of your slide and re-cut the crown to a sleek 11-degrees.  Not only does the crown and flush service give your pistol a truly custom look, but helps to maximize the accuracy potential for your barrel by allowing gas and pressure to exit the barrel in a more uniform manner helping to better stabilize the bullet.  The service also helps to protect the rifling by drawing the rifling further back while maintaining the edges of the lands and grooves and disallowing carbon build-up around the muzzle, helping to keep the muzzle clean and free of debris.
