Why The MDT ACC Elite Is the Best Competition Chassis In The World

One evening while browsing GunBroker, I spotted the perfect rifle—a full custom build featuring a Falkor Defense 7 action, a Bartlein barrel chambered in 6GT, and the formidable MDT ACC. It was a true turnkey precision rig, built for performance and looking every bit the part with its silky-smooth action, crisp trigger, and that iconic ACC chassis. Beyond its good looks, the ACC delivered unmatched functionality: a long, weight-tunable forearm with both internal and external options, and a fully adjustable rear, making it the ultimate performance platform.

After a few years of running the ACC chassis, word of its successor began to leak out. MDT was working on a new evolution—the ACC Elite. It took some time for the new chassis to officially drop, but once it did, it proved well worth the wait.

Let’s talk about the ACC Elite. This chassis is packed with features that put it in a class of its own when it comes to competition rifles. The low bore axis drives recoil straight back into your shoulder, keeping the rifle flat and manageable. The fully toolless adjustments on the rear buttstock are unmatched—length of pull and comb height can be dialed in on the fly, while the buttpad still offers the cant and height adjustability we loved from the original ACC, now without the need for tools. And tucked neatly under the cheek piece? Two onboard wrenches to handle any adjustment the ACC Elite might call for.

Move forward a bit, and more standout features appear. First is the adjustable thumb rest: mounted in an M-LOK slot, it lets you position your thumb for added control and reduced wobble. Just below it, the trigger well features a bottom slot for quick access when fine-tuning adjustable triggers. The Elite Grip includes a connecting rod linking the grip to the buttstock, adding even more rigidity to the rear of the chassis. MDT also added traction tape above the trigger well—perfect for indexing your finger during transitions or before settling onto the trigger.

Up front, the handguard stretches a glorious 19 inches and has been beefed up for even greater stability and rigidity. The increased thickness allows you to bolt in both control bridges, letting you apply downward pressure over the top without contacting the barrel, or mount a clip-on optic—night vision, thermal, whatever your setup demands—in front of your scope.

And that’s just the start. The ACC Elite opens the door to an incredible range of configuration options. This chassis has been used for just about everything. I’ve seen it run in ELR matches, and it’s available in inlets for both Tikka and Remington actions—short and long—so it fits a wide variety of builds. Shooters have also turned the ACC Elite into lightweight hunting or NRL Hunter rigs by stripping internal weights, pairing it with a carbon barrel, and choosing lightweight optics and actions. You still get all the versatility, adjustability, and precision of the ACC Elite, just in a mountain-ready package. On the opposite end, I’ve seen .22 LR builds tucked neatly between those frame rails for PRS22, NRL22, and other rimfire competitions. But you don’t need to compete to enjoy it—its rigidity and precision make it perfect for plinking or building confidence in new shooters. I’ve even seen compact “Shorty” builds with 20-inch barrels, suppressors, night vision, or thermal optics—ideal for predator control or hog hunting after dark. The ACC Elite truly adapts to whatever role you need it to fill.

Think about all the ways you could put the ACC Elite to work. My current setup is built for competition, but who knows—my next ACC Elite build might be a dedicated hunting rifle. This chassis has helped me win and place high in PRS and team matches, and it’s just as valuable when I’m working with new shooters. Whether we’re stacking bug holes at 100 yards or ringing steel out to 1,000, the ACC Elite’s adjustability makes it easy to fit nearly anyone behind the rifle.

If you haven’t had the chance to shoot an MDT ACC Elite yet, the next time you spot someone running one at the range, ask if you can get behind it. I think you’ll love it as much as I do.
