DETAILS
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/RRS 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 SRS-X ESS compatible buttstock (sold separately)and AR15 compatible pistol grips (sold separately).
The ACC chassis accepts AICS-pattern external box magazines, and supports installation of M-Lok patterned accessories along the forend. The full length Arca/RRS standard dovetail allows shooters to mount a wide variety of accessories with infinite adjustment, which is now a standard among the competitive community.
