Description
The MDT CRBN chassis transforms a factory Tikka T3X into a precision-ready rifle that won't wear you out in the field. Built from high-quality carbon fiber with a magnesium micro chassis and V-block bedding system, this is about as close as you get to serious performance without the weight penalty that usually comes with it. You're getting a rock-solid action foundation with the adjustability and accessory compatibility that modern hunting demands.
Lightweight Precision for Mountain Hunting and Competition
The entire stock is filled with rigid foam that dampens recoil and harmonic vibrations. That translates to a steadier shooting platform and better trace spotting between shots. The foam also means this thing deadens the metallic ring you get from a lot of modern chassis systems, so your rifle handles more naturally when you're behind the scope. Compared to traditional aluminum chassis setups, you're shedding real weight without compromising any rigidity where it actually matters.
Built-In Versatility
The integrated fixed ARCA rail runs the full length of the forend, giving you immediate compatibility with ARCA-compatible bipods, tripods, and accessories. M-LOK slots dot the forend for additional mounting options if you want to add lights, rail sections, or other gear. QD cup mounts front and back let you dial in your sling setup for either hunting or competition use. The adjustable length of pull via spacers and integrated thumb shelf mean you're not forced into an uncomfortable position to get behind your scope.
Ready to Run
The drop-in fit for long action T3X rifles means minimal gunsmithing headaches. Everything you need is built in, from the bedding to the accessory compatibility. This chassis works with your existing bottom metal or pairs seamlessly with MDT's Hunting or Precision bottom metal options, depending on what you're after.

Frequently Asked Questions
Does the MDT CRBN chassis for Tikka T3X require any modification to install?
No significant modifications needed. This is a drop-in chassis designed specifically for Tikka T3X long action right-hand rifles. It will fit with minimal gunsmithing. If your rifle uses a CTR or similar aftermarket bottom metal system, the chassis transitions you to Badger M5-style bottom metals, which is a straightforward swap.
What's the actual weight advantage of this carbon fiber chassis?
The CRBN weighs approximately 27 ounces without bottom metal, about 30-31 ounces with hunting or precision bottom metal. While it's not the absolute lightest option available, the weight savings compared to aluminum chassis are meaningful for mountain hunting, and the rigid foam construction adds back stiffness without adding metal weight.
Can I use this chassis for both hunting and competition?
Absolutely. The ARCA rail, M-LOK compatibility, adjustable length of pull, and QD cups make it equally at home on a mountainside or at a precision rifle match. The design balances versatility with function, so you're not pigeonholed into one discipline.
Does the foam filling inside the CRBN chassis really make a difference in recoil management?
Yes. The rigid foam dampens harmonic vibrations and recoil, which gives the rifle a noticeably 'deadened' feel compared to hollow aluminum chassis. This translates to better trace spotting between shots and a more natural handling experience during extended shooting sessions. It also helps reduce the metallic ringing common with lighter platforms.
