WMR 22 Magnum Bolt Assembly

The Select Fire Magnum Bolt is made from solid 4140 steel stock. It is manufactured using state of the art CNC equipment. The bolt is then sent out for heat treat to harden it. After heat treat we polish any rough surfaces and then have them put through a sealing process. The bolt is then assembled with our Black Diamond extraction claw, spring & plunger, Black Diamond Firing Pin, spring and roll pin. All of the parts are made by Select Fire. These are high quality bolt assemblies that are made specifically for our Select Fire Magnum Receiver...... ...... As Stated, our MAGNUM Bolt is CNCed from solid 4140 steel. It is not a substitute for the Ruger Magnum Bolt. Our bolt was not made for Factory Ruger Magnum receiver as it is not made of Tungsten and MAY NOT keep the breach closed long enough on Ruger model Magnum Rifles. Our bolt is designed to work with a secondary main spring engineered into the Select Fire Magnum Receiver only! ________With that being said, customers have purchased this bolt assembly to replace their failed Ruger magnum bolt and claimed that it functioned without issue! Note: Once purchased and cycled it is no longer returnable.
