Samson Manufacturing SAS/22™ Tactical Folding Chassis System - Integrated SAS-K Push-Button Folding Stock, 10.5" M-LOK Handguard, 3.75" Picatinny Scout Rail, Fits Ruger 10/22 Takedown, 6061-T6 Aluminum, MIL-A-8625 Type III Hard-Coat Black Anodized - 04-06172-01 / 840478600407
Product Description
Transforming the classic Ruger® 10/22 Takedown® into an ultralight, packable tactical rimfire rifle requires a chassis engineered for seamless break-down, return-to-zero optical mounting, and true side-folding utility. Factory polymer or wooden stocks leave Takedown rifles stored in two awkward loose pieces that lack tactical accessory rails, adjustable cheek weld geometry, and modular handguard mounts on your bench. The **Samson Manufacturing® SAS/22™ Tactical Folding Chassis for Ruger® 10/22 Takedown® (04-06172-01 / 840478600407)** solves these transport and ergonomics limitations, combining Samson's combat-proven **SAS-K side-folding stock mechanism** with a precision-milled 6061-T6 aluminum chassis built exclusively for the two-piece Takedown receiver pattern.
Proudly engineered, CNC-machined, and hard-coat anodized in Keene, New Hampshire by Samson Manufacturing, the SAS/22™ Takedown Chassis turns your rimfire into the ultimate backpack, survival, or bug-out rifle. Built from aircraft-grade **6061-T6 billet aluminum** treated with a MIL-A-8625 Type III Class 2 matte black finish, the chassis incorporates a 10.5-inch 5-sided M-LOK® handguard and an integrated 3.75-inch (9-slot) 1913 Picatinny scout rail forward of the receiver hinge. The integrated SAS-K folding stock mechanism locks down flat, collapsing the bare chassis length to just **11 inches** (or 24.5 inches with a standard 16-inch barrel installed). Outfitted with push-button length-of-pull (LOP) and cheek riser height adjustments, ambidextrous QD sling attachment sockets, and a Magpul® MOE-K® grip, this turn-key tactical upgrade elevates your rimfire build straight from your armorer bench.
Engineered to drop natively onto factory Ruger® 10/22 Takedown® receiver assemblies and standard Takedown pattern clones, this factory-calibrated aluminum chassis guarantees rock-solid rigidity and compact packability directly from your workspace bench.
*Armorer Bench Notes & Real-World Takedown Staging Guidance: The Samson 04-06172-01 SAS/22™ Takedown Chassis package arrives workspace ready, containing the two-piece hard-anodized aluminum chassis body, integrated SAS-K folding stock, Magpul® MOE-K® grip, scout rail, and assembly hardware. RUGER 10/22 TAKEDOWN HOST RECEIVER COMPATIBILITY MATRIX: This chassis is engineered natively, strictly, and dimensionally to fit **factory Ruger® 10/22 Takedown® models and 10/22 Takedown® pattern clone receivers**. *Standard Fixed 10/22 Notice:* This model (04-06172-01) features a two-piece handguard and receiver split designed specifically for Takedown models—it will *not* install on standard fixed-receiver 10/22 rifles (which require Samson SKU 04-06171-01). Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host 10/22 Takedown® rifle is completely clear of live ammunition, the magazine is removed, and the chamber is checked safe and empty. 2. Separate the factory 10/22 Takedown® barrel assembly from the receiver group using the barrel locking lever. 3. Remove the factory stock mounting screws to free the receiver and forend assemblies from their OEM stocks. 4. Seat the Takedown receiver into the rear SAS/22™ chassis housing and secure using the included takedown screw on your bench. 5. Install the forward 10.5-inch M-LOK® handguard shell onto the barrel assembly block. 6. Re-engage the barrel locking mechanism, adjust the push-button cheek riser and stock length of pull (approx. 12" to 13" LOP), test the push-button folding lockup, and verify clear sight alignment through your scout-mounted optic before rolling downrange.*
