GREY BIRCH LACHASSIS 16 | RUGER 10/22 | FOLDING
The Long-Forend LaChassis for Ruger 10/22.
The Grey Birch MFG LaChassis 16 is the Ruger 10/22 folding chassis with a 16″ forend, M-LOK and ARCA-Swiss attachment options, and a second rear receiver-tension point. It gives a familiar rimfire action an adjustable, folding platform with room to position bipods and other equipment where you actually want it.
A good 10/22 can become a very different rifle with the right foundation. The LaChassis 16 gives you an extended forend for support and accessory placement, a cutaway around the magazine well for access, an adjustable cheek weld and length of pull, and a folding rear stock. Use it for: long-forend rimfire builds, bench and range shooting, positional training, and 10/22 projects where adjustability and mounting space matter.
Sixteen Inches of Forend. Not a Barrel Length.
The “16” identifies this model’s 16″ modular forend, not the length of the barrel included in the purchase. The chassis does not include a barreled action. Forend length changes how much space you have for your support hand and equipment, particularly with a bipod mounted forward. Check your specific barrel length, profile, muzzle device, and muzzle clearance before ordering; do not assume that a barrel of a certain nominal length extends beyond the handguard in the required way.
Secure the Action. Adjust the Rest.
Grey Birch builds the LaChassis around 6061-T6 aluminum and a distinctive rear tension point that supports the 10/22 receiver at a second location. The folding stock adjusts for length of pull and cheek weld and can be locked in its fixed position. The forend supports both M-LOK and ARCA-Swiss mounting, with ambidextrous QD sling points and an AR-pattern grip mounting position. The grip is your choice and is sold separately.
Pair It With: Three Useful Additions.
The LaChassis includes a grip-compatible mounting point but does not include the grip itself. Complete the essentials with a compatible grip, add swivels for the chassis QD points, and consider a small Pete’s Pillars hardware refresh while the rifle is apart.

Frequently Asked Questions
Ruger 10/22 fitment, long-forend clearance, grip, folding stock and build choices.
Which rifles does this LaChassis 16 fit?
This specific listing is for the Ruger 10/22, not Tikka T1x or CZ 457. It is designed around compatible 10/22-pattern receivers and trigger groups. Takedown and unusual aftermarket receiver configurations require separate fitment verification with Grey Birch before ordering.
Does “16” mean it comes with a 16-inch barrel?
No. The 16″ measurement describes the forend. This chassis does not include a rifle, receiver, barrel or trigger group. Confirm the barrel and any muzzle device extend appropriately beyond the forend, and follow the manufacturer’s clearance guidance for your exact configuration.
Will my heavy barrel or muzzle device clear the forend?
Barrel channel dimensions for this exact 16″ model are not established in the available manufacturer information. Check the outer diameter, barrel length, and muzzle accessory clearance with Grey Birch before ordering. Do not rely on clearances published for the shorter LaChassis versions.
Does it come with a pistol grip?
No. The chassis provides an AR-pattern compatible grip mounting point, but the grip is a separate choice. The Ergo Flat-Top Grip is an available option, and you can browse additional rifle grips.
Can I mount an ARCA bipod, M-LOK accessories or QD sling?
The 16″ forend is designed for ARCA-Swiss and M-LOK mounting, while ambidextrous QD points are provided on the forend and stock. Choose your mounting hardware to suit the particular accessory. Our GrovTec QD swivel 2-pack can pair with compatible QD sockets.
Can the stock be locked to prevent folding?
The LaChassis folding-stock design supports locking the stock in a fixed configuration. Check the instructions for your exact generation and configuration before changing the folding mechanism.
How does it compare with the MDT Field Stock, KRG Bravo or other 10/22 parts?
We carry each for a different style of build. The LaChassis 16 stands out for its long forend, folding format and rear receiver tension point. The MDT Field Stock offers a more traditional stock shape, while the KRG Bravo and MDT Oryx offer different chassis ergonomics. For a complete rifle refresh, consider a TandemKross trigger or a Volquartsen Competition Bolt. KIDD is another respected 10/22 trigger option we carry. Always verify fitment details with Grey Birch or the relevant manufacturer as model specifications and production details can change.
