MDT ACC Premier Gen 2 CZ 457 – Fixed SRS-X Lite Buttstock
The MDT ACC Premier Gen 2 is an advanced rifle chassis designed for shooters who require high rigidity, excellent ergonomics and extensive rifle configuration options.
The version dedicated to the CZ 457 provides an excellent platform for building a precision .22 LR rifle for training, PRS Rimfire competition and long-range rimfire shooting.
This version is equipped with the fixed MDT SRS-X Lite buttstock.
Designed for Precision Shooting
The ACC Premier Gen 2 is manufactured from precision-machined aluminium, providing a highly rigid and stable platform.
The CZ 457 action is secured in the chassis using a V-shaped bedding system, providing consistent contact between the action and chassis and helping maintain repeatable positioning.
The chassis has been designed to allow shooters to adjust both ergonomics and rifle balance according to their individual preferences and shooting discipline.
Full-Length ARCA Rail
The underside of the 15-inch forend features an integrated full-length ARCA rail.
This allows bipods, tripods and other ARCA-compatible accessories to be quickly repositioned without the need for an additional mounting rail.
This is particularly useful in PRS competition, where the rifle's support position often needs to be adjusted between different shooting stages and barricades.
M-LOK System and Adjustable Rifle Balance
The forend also features multiple M-LOK interfaces for mounting additional accessories.
The ACC Premier Gen 2 is compatible with MDT internal weights, allowing the shooter to increase the overall rifle weight and adjust its centre of gravity.
This makes it possible to configure the rifle for both dynamic PRS stages and more static precision shooting applications.
Fixed MDT SRS-X Lite Buttstock
The chassis is equipped with the MDT SRS-X Lite, a lightweight and rigid fixed buttstock designed for systems such as the ACC Premier Gen 2.
The buttstock provides adjustment of the key ergonomic parameters, including:
- cheek riser height,
- length of pull,
- buttpad position,
- overall rifle fit to the shooter's individual position.
The fixed design eliminates the folding mechanism and provides a simple and rigid configuration particularly well suited to competition rifles.
Adjustable MDT Vertical Grip Premier
The chassis includes the MDT Vertical Grip Premier.
The grip allows adjustment of its position and angle to suit the shooter's hand position and trigger finger placement.
Its more vertical grip angle helps maintain a natural hand position when shooting prone or from barricades.
Integrated Thumb Rest
The ACC Premier Gen 2 features a wide, integrated thumb rest, allowing the shooter to maintain a comfortable and repeatable thumb position.
This can help reduce unnecessary tension in the firing hand and promote a consistent grip on the rifle.
Integrated Barricade Stop
A wide, aggressively textured barricade stop is integrated directly in front of the magazine well.
It allows the rifle to be firmly loaded against a barricade or other support without applying pressure directly to the magazine.
Extensive Upgrade Options
The ACC Premier Gen 2 chassis supports a wide range of MDT accessories, including:
- internal chassis weights,
- Control Bridge,
- NV Bridge,
- additional M-LOK accessories,
- ARCA-compatible accessories.
This allows the rifle to be progressively configured and upgraded according to the shooter's changing requirements.
