Volquartsen Firearms Competition Bolt for Ruger MKII, MKIII, MKIV, VC4BT-B

Product Description

The Volquartsen Firearms Competition Bolt, part number VC4BT-B, is a competition bolt for the Ruger MKII, MKIII and MKIV pistols. One part number covers all three models, so you do not have to sort through separate versions.

This is a part, not a complete firearm. It is the bolt, the piece that moves back and forth in the pistol’s action, and Volquartsen offers it as an upgrade for shooters who run these Ruger pistols in competition. The manufacturer’s notes also mention MKIII pistols and the loaded chamber indicator. If you own an MKIII, read those notes and confirm how the bolt works with that feature before you order.

Who it suits

This bolt suits owners of a Ruger MKII, MKIII or MKIV who are building or tuning a pistol for match use. It also makes sense for anyone already working through a Volquartsen parts list for one of these guns.

Pair it with other parts made for the same Ruger pistols, such as triggers, barrels or sights, plus a good set of cleaning tools to keep the action running smoothly. If you are not sure which of the three models you have, check the markings on your pistol before ordering. Keep the part number VC4BT-B handy when you compare it with other bolts or parts.
