First Look: MDT ACC CZ 455 Rifle Chassis

posted on June 20, 2019

Modular Driven Technologies, known for the company's line of outstanding rifle chassis, is adding an option for the CZ-USA 455 rimfire action in the form of its Adjustable Core Competition Chassis (ACC).

This option for the ACC CZ 455 was designed with competing in precision rimfire in mind to provide competitors more accessory options and greater control over weight and balance adjustability of their rifles. The ACC CZ 455 chassis also allows a user to set up a precision rimfire trainer which mimics the ergonomics of their ACC centerfire competition rifle, greatly increasing the training potential and reducing training costs.

“The ACC is the most-advanced competition chassis in the MDT line up,” says Matt Hornback, public relations manager, “it was a logical next step to make it available for the popular CZ 455 rimfire.”

The MDT ACC chassis was developed with guidance from Team MDT competitive shooters and other precision shooters from around the world, and the ACC's superior ergonomics and features as well as the fully customizable steel weight system are the result of their input. The customizable weight system of the MDT ACC is built into the buttstock, barrel channel and fore-end, which allows over 9 additional pounds to be added to the rifle chassis assembly, allowing shooters to perfectly balance their rifle for shooting in a variety of different situations.

The ACC comes complete with a Skeleton Rifle Stock with a 13.375-14.375-inch length-of-pull. The Skeleton Rifle Stock also comes with a steel butt pad plate for added weight and includes a dedicated space to add even more weight to the stock if needed.  The chassis also features a full Arca rail the entire length of the fore-end, and it can also accept a traditional pistol grip or the new MDT adjustable vertical grip.

Prices on the MDT ACC starts at $999 (including buttstock), and more information is available at

Controlling the Reactionary Gap

More space equals more time equals more opportunity to solve the tactical problem. The converse is also true: Less space equals less time equals fewer opportunities to solve the tactical problem.
