Description
If you're running PRS matches or any serious long-range competition, the MDT ACC Elite Chassis sits at the center of what winning rigs are built around. This isn't marketing hyperbole—it's the most used chassis in competitive precision rifle shooting for a reason. The engineering behind it comes directly from working with people who live on the range, and everything about it reflects that practical knowledge.
What Makes the ACC Elite Platform So Solid
The fundamentals are rock solid. You get a 19-inch M-LOK forend that's wider, thicker, and longer than previous designs, purpose-built to eliminate any flex. That strengthened forend sits on a solid center base with a connector bar linking the grip to the buttstock, creating a chassis that won't twist or bend when you load into props or take recoil. The aluminum construction handles the beating, finished with hard anodized coating and Cerakote in Titanium Blue for durability in field conditions. Your rifle settles faster and stays on target because the platform itself stays rigid.
Tuning Your Rifle to Perfection
The integrated weight management system is where competitive shooters get their edge. You can add or remove weights from the forend and buttstock, internally or externally, without pulling your barreled action out of the chassis. This means you dial in perfect balance for each stage without burning time. The included SRS-X Elite buttstock features tool-free adjustments for length of pull (12.25 to 14.75 inches), cheek rest height, and buttpad position. The MDT Vertical Grip Elite with connector bar and adjustable M-LOK thumb rest handles grip positioning, and the ambidextrous magazine latch works flawlessly with AICS-pattern mags. Everything adjusts, and nothing shifts during shooting.
Setup Built for Speed and Control
The full-length ARCA forend rail lets you position your bipod exactly where you need it, and M-LOK slots take additional weights, Baker Wings, or any compatible accessories. The forend is drilled and tapped for mounting Night Vision hoods or control bridges. The underside comes with grip tape you can install for barricade work. This is a competition chassis that shows up on podiums because it gives you the stability and control to run stages efficiently while keeping follow-up shots sharp. Whether you're stacking rounds at 100 yards or pushing steel out to 1,000, the ACC Elite keeps your rifle moving where you're pointing it.

Frequently Asked Questions
Does the ACC Elite chassis work with standard Remington 700 short action magazines?
It uses AICS-pattern magazines, which is the standard for modern competition rifles. Most modern Remington 700 short action builds use AICS mags, but if you're using older factory Remington mags, you'll need to switch. The adjustable magazine latch ensures everything feeds smoothly without any play or slop.
How adjustable are the stock and grip, really?
The SRS-X Elite buttstock adjusts length of pull from 12.25 to 14.75 inches with included spacers, plus cheek rest height, back and front position, and buttpad height. The Vertical Grip Elite adjusts back, front, angle, and includes an adjustable M-LOK thumb rest on both sides. Most shooters find their exact fit without needing anything aftermarket.
Can I swap out the included buttstock or grip for other MDT parts?
Yes. The buttstock uses MDT's XTN interface, so any other MDT stock that's XTN-compatible will work, and adapters exist for AR-15 buffer tube stocks if you want that route. The grip is AR-15 compatible, so you can run any AR-style grip if you prefer something different.
What's the weight of the chassis without any added weights?
It comes in at 6.1 pounds as a base unit. From there, you can dial in your balance point by adding internal weights to the forend, external M-LOK weights, or buttstock weights depending on your barrel profile and action. Most competitive builds end up somewhere between 6.5 and 9 pounds for the chassis itself.
