The CST ClassX-22 Rimfire Receiver combines precision craftsmanship in classic form for the very best 10/22 receiver available for your next build. Features the same rounded surface and mounting hole pattern as the factory 10/22 receiver. Light weight with all the sight setup possibilities as with a factory receiver, but with the same precision machining and excellent fit and finish CST is known for. Every receiver is hand deburred and polished, one at a time.

Every CST ClassX-22 Rimfire Receiver features the “Fill-The-Gap” barrel clamp system, eliminating barrel droop. Receiver includes the Barrel Clamp and fasteners along with all cross-pins. Demo Video: https://youtu.be/I1ZJmSNasEc
