Upgrade your Ruger® 10/22® with a spiral-fluted, blued chromoly bull barrel that pairs show-quality styling with match-grade performance. What makes it special Distinctive spiral fluting: Spiral flutes add upscale, showroom-ready styling while preserving the mass and rigidity of a .920" bull contour for stable harmonics and repeatable aim. Match-grade manufacturing: Bored & rifled by Lothar Walther (Germany), finished and hand-machined by Tony Kidd, and chambered with a proprietary reamer for smooth, reliable feeding. Extraction reliability: Precision convex extractor slot keeps the extractor perfectly aligned with the case rim — a tight-tolerance feature that eliminates common extraction problems. Durable finish & fit: Black bead-blasted chromoly with a durable blued finish and a slip-fit design for easy installation in factory and most aftermarket 10/22® receivers. Guaranteed accuracy: ½" at 50 yards (5-shot group) — proven performance you can depend on.

We eliminate droop with: A precise fit between tenon and receiver, with a consistent diameter along the tenon length. A precisely machined shoulder with a relief cut to allow the shoulder to seat flush against the receiver providing full support. When properly fitted, v-block screws only need to be snug (~10 in-lb) — tight enough to prevent forward movement without distorting alignment.Installation tips If using another brand of receiver clean paint/build-up from the receiver mortise before installing. Apply a light coat of grease to the tenon to ease installation—use sparingly. Begin inserting the tenon while aligning the extractor slot. Tap the rear of the receiver with your palm; if resistance increases, use a rubber mallet to fully seat. Recheck extractor alignment by matching the level of the receiver’s bottom flat with the barrel’s v-block cutout. Run two magazines through the barrel before evaluating groups, and repeat when changing ammunition brands. Keep the chamber clean but avoid over-cleaning the bore—excessive cleaning can reduce accuracy. Typical bore cleaning interval~ every 500 rounds, depending on ammo
