First Look: MDT ACC Chassis for CZ 457 Rifles

posted on November 5, 2019

Interest in .22 LR precision rifle competition shooting has greatly increased in recent years. Custom .22 LR rifles with features like modular chassis and high-end optics are a common sight at these matches, and Modular Driven Technologies, MDT, is one of the leaders in precision rifle chassis building. Now Modular Driven Technologies is bringing the most advanced competition chassis in the MDT lineup, the MDT ACC, to the popular CZ-USA 457 rimfire rifle.

The CZ line of rimfire rifles is growing more and more popular, and the refined CZ 457 model is one of the company's most popular options. Built for a number of activities such as hunting, plinking or precision rimfire rifle competitions, it’s a proven, solid performer on the range or in the field. The MDT ACC chassis for the CZ 457 allows users to build a rifle to their unique needs to dominate precision rimfire competitions or just enjoy a day plinking on the range.

The MDT ACC was developed with the input from competitive shooters from around the world, resulting in the ACC's superior ergonomics and features. The ACC’s fully customizable steel weight system is what sets it apart from the field. The weight system is built into the buttstock, barrel channel and fore-end, allowing more than 9 additional pounds to be added throughout the rifle chassis assembly. This additional weight allows the shooter to balance and tune their rifle to their exact needs for effortless and accurate positional shooting.

Each ACC comes complete with a Skeleton Rifle Stock (SRS-X Elite) with a 13.375- to 14.375-inch length of pull. The ACC Chassis features a full Really-Right-Stuff-spec Arca rail the entire length of the 17.75-inch fore-end and can accept a traditional pistol grip or the MDT adjustable vertical grip.

MSRP on the ACC chassis for the CZ457 starts at $999, and more information is available at

Training yourself to shoot better is the result of developing a higher skill level upon which you may rely. The higher your skill level, the greater your odds of performing well when they are called upon. Greater skill is born from greater control; the greater the control, the better the performance.

Your Go-To Move

When it comes to a self-defense situation, most shooters think “Well, I’ll just shoot him!” Others may consider their personal “go-to” move to be a martial arts technique such as a finger strike to the eyes, bare-knuckle punch to the throat or kick to the groin.
