CURRENTLY AVAILABLE: I currently have the Comp Chassis (slick side) and Comp Lite Chassis (with side cuts) available in black and gunmetal grey and I have the NPVC Foam Barrel Grips and M-LOK rails. The Comp Chassis weighs only 8.92 ounces and the Comp Lite weighs just 8.40 ounces. I’ll have more colors and my new extruded 6061T6 aluminum handguards soon! This version of my chassis is designed for building lightweight competition rifles or other competition rifles (obstacle course, bench) with the optional M-LOK rail or handguards. It is of course suitable for building plinking or hunting rifles also! It will fit most 10/22-style receivers, except those with a fixed tang. NOTE: For Volquartsen triggers, I have a special grip insert – please let me know when you order. All my chassis feature a precision adjustment screw at the base of the receiver that pins down the back of the receiver for a custom, super-tight fit with any standard 10/22-style receiver – no tangs, inserts, or bedding needed! And no modification of the receiver necessary! This is a “set and forget” feature – adjust it during the initial assembly procedure and then install the buffer tube. The firearm will still disassemble/assemble with the single Ruger® 10/22 factory takedown screw. The chassis is CNC-machined from a single billet of “military-grade” 6061-T6 hardened aluminum alloy and then finished with a very durable anodized finish. Precision machining, receiver adjustment screw custom fit, and free-floating barrel design maximize accuracy. Accepts all Ruger® 10/22-style barrel profiles including 0.920-inch “bull” barrels. Accepts all Ruger® 10/22-style receiver profiles including those with integrated top rails, but does not fit receivers with a rear tang. Drop-in installation – no modification of your Ruger® 10/22 is required. Base price includes the chassis, all necessary hardware (screws, grip spacer, etc.), and instructions (10/22-style firearm, stock, grip, and handguard not included or extra).
