This is a new Volquartsen Competition Bolt for 10/22 pattern firearms. Complete CNC-Machined Bolt features our hardened and tuned extractor for positive, consistent extraction. It also includes our round titanium firing pin. This round design eliminates the unnecessary movement found on most 10/22 firing pins. The CNC-machining process allows us to hold the head spacing to exact dimensions eliminating the need to have your factory bolt reworked.
