The MDT ACC Premier Gen2 chassis takes the DNA of MDT's flagship Elite platform and brings it to the CZ 457 in a package that makes sense for a rimfire build. It drops your barreled action into a precision V-Block bedding system that locks the action tight to the chassis, giving you consistent contact and repeatable groups. Installation stays simple: seat the action, tighten two screws, and you're ready to head to the range with no gunsmithing required.
The heart of this chassis is the compact 15-inch forend. It's wide, thick, and flat, which kills flex and torsion so the rifle sits rock-steady on barricades, bags, and PRS props. Underneath runs a full-length integrated ARCA rail for quick bipod and tripod mounting, and you get roughly 8 M-LOK slots per side for accessories, spare weights, or a data card holder. An integrated tall barricade stop and a wide thumb shelf give you solid, repeatable contact points whether you're prone, on a prop, or off-hand.
Balance is where this platform really shines. The weight management system lets you add mass to the buttstock and to the interior or exterior of the forend, so you can push the balance point exactly where you want it for faster target acquisition and flatter follow-ups. The included MDT SRS-X Lite skeletonized buttstock keeps things light while offering an elevation-adjustable cheek riser and length-of-pull adjustment via 1/4-inch spacers running 12.32 to 13.32 inches. An adjustable MDT Vertical Grip – Premier comes in the box, and the chassis accepts standard AR-15 style grips if you want to swap.
MDT redesigned the magazine area for the CZ 457 with a large relief cut around the magwell, making mag changes off the bench noticeably smoother. It's built from hard-anodized 6061 aluminum with a Cerakote finish for durability, includes QD sling cups, and is drilled and tapped for NV and control bridges when you're ready to expand. For anyone building a tactical-style CZ 457 with a shorter barrel, the 15-inch forend and tunable balance make this a smart, capable foundation.
No. You simply drop your CZ 457 barreled action into the V-Block bedding and tighten two screws. It's a straightforward drop-in that most folks handle at home in a few minutes with basic tools.
The compact 15-inch forend comfortably accommodates barrels starting around 17 inches, which makes it well suited to shorter, more tactical-style CZ 457 builds. If you run a longer barrel, MDT offers an optional forend tip weight that adds usable forend space and helps balance the rifle.
Yes, that's one of its strongest features. The weight management system lets you install up to four interior forend weights, add M-LOK exterior weights, or fit a buttstock weight to tune your balance point exactly where you want it. This is a big help for finding targets quickly and settling into follow-up shots.
It does. The chassis ships with the skeletonized MDT SRS-X Lite buttstock, which offers an adjustable cheek riser and length-of-pull spacers, plus an adjustable MDT Vertical Grip – Premier. You can also swap in any AR-15 style grip if you prefer a different feel.
