While the Ruger 10/22 is a favorite rimfire rifle for speed shooting competitions and recreational shooting, its not uncommon for the factory bolt to need a complete re-work for the gun to function at its best. Fix common 10/22 bolt issues- without the need for a gunsmith- with the new KrossFire CNC-Machined Bolt from RimEdge. CNC-Machined from hardened tool steel, the KrossFire Bolt features a pinned firing pin to restrict the vertical movement and strike the cartridges in a consistent manner, reducing misfires. The CNC-machining process allows for precise headspace measurement, ensuring the bolt face sits flat against the barrel and improving firing pin impact. The CNC-machined KrossFire bolt features a polished finish that is much smoother than the factory bolt, ensuring the bolt rides smoothly over the hammer for improved cycling and a smoother trigger pull. Upgraded 10/22 bolt includes a laser-cut steel firing pin and steel extractor to reduce failures to fire and failures to eject. The "KrossFire" Bolt fits any standard Ruger 10/22 rifle, Ruger 10/22 Takedown, Ruger 10/22 Takedown Lite, Ruger 10/22 Charger pistol or Ruger 10/22 Charger Takedown pistol, Ruger 10/22 Carbine and Ruger 10/22 Target LITE.
