The ACC (Adjustable Core Competition Chassis) is designed around an integrated, modular weight system which allows you to customize the balance and mass of your rifle to maximize performance and minimize recoil.

The ACC comes with a Skeleton Rifle Stock with a steel butt pad plate, for added weight, and a dedicated space to add even more weight to the stock if required.

The ACC Chassis features a full Arca rail the entire length of the forend and M-LOK mounting points for accessories and additional forend weights - both external and internal - allowing you to add up to an additional 9 pounds of steel to your rifle.


The Adjustable Core Competition chassis system is designed for the competition world: the ACC is primarily suited for the PRS & NRL shooting style, although it can be used in other disciplines. The ACC chassis system is the result of endless testing and collaborating with competition shooters, implementing the most crucial and results driven features, while ensuring accuracy and precision remain unparalleled.

The ACC (keyword A for Adjustable) was created with an integrated weight management system, allowing shooters to fine tune their chassis' weight and balance point. The adjustability comes from a series of weights that can be added to either the buttstock, interior forend or exterior forend M-LOK. It's original weight of 5.9 lbs transforms into a maximum of 12.3 lbs (chassis only - add on your action, barrel, scope and accessories and most shooters are pushing 25-30 lbs in the ACC).

All of this modularity and adjustment can be achieved without taking your barreled action out of the chassis system. Internal forend weights can be inserted from the front of the forend and screwed in place, while external weights were designed to be M-LOK compatible and easily attached on either side of the forend. This ACC weight management system allows shooters to rapidly adjust the feel and recoil characteristics of their system, even while at the range. 

Along with other features like the full 17" ARCA/RSS forend, flared magazine well, extended barricade stop, widened thumb shelf, adjustable cheek riser and length of pull - the Adjustable Core Competition chassis is nothing short of excellence for the competition shooting world.

Mounting and Compatible Accessories

The Acc chassis is designed to accept an ESS compatible buttstock, with a few modifications to provide extra weight and solid lockup of adjustments, while still being tooless. The MDT Vertical Grip was designed a the same time as the chassis and is built for the competitive shooter.

The ACC accepts AICS-pattern magazines and supports installation of M-LOK patterned accessories along the forend. The full length ARCA/RSS standard dovetail allows shooters to mount a wide variety of accessories with infinite adjustment, which is now standard among the competitive community.
