This Pacific Tool & Gauge Bolt Head is a precision machined replacement part for your Savage 110 Series rifle. Perfect for use in benchrest or F-class competition rifles that fire thousands of round per year, PTG's Savage bolt head is not subject to the quick deterioration or bolt face dishing that Savage factory bolt heads tend to display after a high volume of fire. The result is a drastic reduction in primer flow and case head rounding over time. Made in the USA.
