GREY BIRCH LACHASSIS 10 | TIKKA T1X | FOLDING | CLEAR ANODIZED
37 Ounces. Folds to 20.5 Inches.
The Grey Birch LaChassis 10 is a folding Tikka T1x chassis machined from 6061-T6 aluminum in a clear hard anodized finish, and it weighs 37 oz. A 10″ modular forend carries both M-LOK and ARCA-Swiss, there's an integral recoil lug and a magwell cutout, and it folds to 20.5″ or locks permanently in the fixed position if you'd rather it didn't.
Rimfire chassis tend to get heavy fast, and that's fine on a bench and miserable on a hike. At 37 oz this one is roughly half the weight of a full competition chassis, and it folds, which means a .22 that actually fits in a pack or behind a truck seat instead of being the longest thing you own. You still get the parts that matter: an integral recoil lug, length of pull from 13″ to 14.5″, cheek weld adjustment, ambidextrous QD points on both the forend and the stock, and an AR grip mount so you pick your own grip instead of living with theirs. Use it for: backpack and truck guns, squirrel and rabbit hunting, NRL22 hunter-class stages, .22 trainers and any T1x you'd rather carry than lug.
Folding, and Locking If You Want.
Folded it's 20.5″, open it runs 29.5″ to 30.5″ depending on your length-of-pull setting. The hinge can be permanently locked into a fixed position, which matters for two reasons: some matches don't allow folding stocks, and some shooters simply don't want a joint in the rifle. Buying it folding and locking it later keeps both doors open. Assembly and adjustment takes 5/64″ and 5/32″ Allen keys and nothing else.
A 10″ Forend With Both Standards.
The modular forend is M-LOK and ARCA-Swiss compatible at the same time, so you're not choosing a mounting system at purchase. Clamp an ARCA bipod anywhere along the rail, or bolt M-LOK accessories where you want them. The magwell cutout gives your hand somewhere to go on a reload, and the grip-to-trigger geometry was set up for a straighter trigger press. Note that the grip is not included, and neither is the barreled action.
Our Take
A Chassis Is the Frame, Not the Rifle
We machine rifle parts for a living, so here's the honest version: a chassis changes how a rifle fits you and what you can mount to it. It doesn't change how the action feeds, how the trigger breaks or what the barrel does. The T1x is a strong action out of the box, which is exactly why a light folding chassis suits it. Where we come in is the rest of the build — pillar bedding for the rifles still in wood, CZ 455 and 457 parts if there's a CZ in the safe, and custom Cerakote in house with fast in-stock lead times on most builds when you want this chassis to match the rest of your kit.
Ask us about custom Cerakote →About That Clear Anodized Finish.
Grey Birch notes that the finish may not exactly match their website images, and that the shade can vary when you pair it with other parts. That's normal for clear anodize, and it's also fixable. We run custom Cerakote in house with fast in-stock lead times on most builds, so if you'd rather have this chassis in M81 Woodland, Arctic Camo, Snow Camo, Snow White, Robin's Egg Blue or Blaze Orange, or matched to a barrel or action you already own, send us the details. Grey Birch also build the LaChassis for the CZ 457, including an M81 Woodland camo version.

The Next Level
Keep the Build as Light as the Chassis.
- Step one: a grip, because it isn't included. An Ergo flat-top AR grip is the simple answer, or the MDT Vertical Grip Elite if you want adjustable angle and reach.
- Step two: a bipod that doesn't undo 37 oz. The MDT Mountain Bipod is 5.7 oz of carbon and titanium and clamps straight to the ARCA forend.
- Step three, if you want more adjustment than folding: the MDT XRS Tikka T1x trades packability for a full-length aluminium core and V-block bedding.

Frequently Asked Questions
Fitment, folding, grips, finish and building out your CZ 457.
Will it fit my rifle?
It's built for the Tikka T1x, and the barreled action is not included. The T1x and the centerfire T3x are different actions, so this will not take a T3x. Grey Birch don't publish a barrel channel dimension, so if you've rebarreled to a heavy contour, send us the measurement and we'll check it before you order.
What magazines does it use?
Your Tikka T1x factory rimfire magazines. This is a rimfire chassis, so it does not take AICS-pattern centerfire magazines.
Does it come with a grip?
No. It has an AR grip-compatible mounting point, so you choose. An Ergo flat-top AR grip is the simple answer, and the MDT Vertical Grip Elite or Pistol Grip Elite give you adjustable angle and reach. Browse all our rifle grips.
Can I lock the folder so it doesn't fold?
Yes. The stock can be permanently locked into a fixed position. That's worth knowing if your match rules exclude folding stocks, or if you just prefer a rifle without a hinge. Buying the folder and locking it later gives you both options.
M-LOK or ARCA for my bipod?
The 10″ forend takes both, so run whichever you already own. An ARCA bipod like the Ckye-Pod Gen 3 Compact clamps anywhere along the rail. If you're keeping the build light to match the 37 oz chassis, the MDT Mountain Bipod is 5.7 oz, and the GRND-POD is the low-profile M-LOK option.
Will the finish match my other parts?
Grey Birch says the clear anodize may not exactly match their website images and that the shade can vary alongside other parts, which is normal for clear anodize. If you want a guaranteed match, we run custom Cerakote in house with fast in-stock lead times on most builds and can finish this chassis to your spec. Tell us what you need matched. Grey Birch also makes it in M81 Woodland camo.
How does it compare to the other T1x chassis you carry?
We only carry parts we trust, can stand behind and know are built with quality, so you're in good hands either way. Grey Birch's advantage here is weight and packability — nothing else we stock folds to 20.5″ at 37 oz. If you want more adjustment and don't need it to fold, the MDT XRS T1x has a full-length aluminium core and V-block bedding, the Oryx Sportsman is the straightforward aluminium chassis, and the LSS-RF Gen2 is the modular skeleton-stock route.
Does Pete's Pillars sell more than chassis?
Yes. We machine our own CZ 457 firing pins, extractors, cocking indicators, magazine releases, bolt knobs, rails, match barrels and pillar bedding here in Michigan, and we run custom Cerakote in house. We also carry chassis from MDT, XLR and Grey Birch, barrels from Lilja and L3i, magazines, optics, bipods and reloading gear like the Area 419 ZERO press.
