A precision machined rimfire receiver that fits everything that fits the Ruger 10/22 receiver: Barrels, stocks, magazines, triggers, etc. Use the X-Ring to replace your factory 10/22 Receiver, OR... Use it to build a completely new gun by combining it with 10/22 accessories! (Recommended trigger guard assemblies: Ruger and Volquartsen).Special Features -Machined from a solid block of 6061 T6 Billet, the X-Ring is held to extremely tight tolerances. The unique X-Ring Bolt has two recoil springs and guide rods... This give an even tension to the bolt (factory 10/22 bolts have one off-center spring and guide rod). Integral Scope Mount and More - In addition to the precision fit and double spring bolt features, the X-Ring receiver also has an integral 15 MOA Picatinny/Weaver scope mounting base, a rear buffer pin, and a rear cleaning rod access hole. Includes Custom Bolt and Bolt Handle. Trigger group is not included (Ruger or Volquartsen trigger group is recommended).Use 10 Round Ruger Factory 10/22 Magazines - Sorry, the high capacity 25+ round magazines just don't work well with the X-Ring receiver. The Ruger factory 10 round 10/22 mags work best.How to Order an X-Ring Receiver: When you order, download your dealer FFL or ask that dealer to FAX (320-834-3002) or email ([email protected]) a copy of their FFL to us (EABCO) along with your name and order number.
