Adjustability Features
SPUHR designed the SICS™ for a perfect fit and maximum performance.
Pistol Grip
The SICS™ uses a proprietary pistol grip, designed to comfortably fit a wide range of hand sizes without creating tension during prolonged trigger engagement. The pistol grip is rubberized for a non-slip grip and can also be adjusted for length-of-pull.
Length-Of-Pull 
The stock assembly allows for rapid tool-less length-of-pull (LOP) adjustment by pinching the LOP levers and moving the LOP Bar and Butt Plate Assembly to the desired position. The total span of rapid LOP adjustment is 50 mm (1.97”) but the Butt Plate Assembly can also be fitted with a spacer to further extend the LOP.
The LOP Bar can also be fitted with pre-set stops for minimum and maximum LOP, making it easy to quickly get into a proper firing stance/position with a minimum amount of motion.
Cheek Piece
The rubberized cheek piece can be adjusted for height and for lengthwise position. The height adjustment is easily made using a wing nut on the side of the cheek piece slide. Lengthwise adjustment of the cheek piece position requires a Torx 20 key.
Butt Plate Height
The Butt Plate Assembly, featuring a Limb-saver® Airtech® recoil pad, allows for rapid tool-less adjustment of the recoil pad height by depressing the Butt Plate Locking Button while sliding the Butt Plate Assembly to the desired position. The total adjustment span is 30 mm (1.18”).
Modularity features
An extension of adjustability is modularity. Modularity allows you to tailor your SICS™ to your needs, and to build a tool that will work with you and has the possibility to change over time, or for different purposes.
Spuhr® Interface™
The Spuhr Ideal Chassis System™ features one of the hallmarks of the Spuhr Ideal Scope Mount System™: the Spuhr Interface™.
Using a systemic approach, the integration of the Spuhr Interface™ into the SICS™ allows users to fully configure their rifle as needed, being able to move accessories between their scope mount and their chassis, enabling the perfect setup for any intended use.
The Spuhr Interface™ consists of a female and a male interface surface, featuring circular grooves and ridges mating around an M4 screw. This interface design does not have any sharp edges and has the best repeatability on the market.
Forend 
The SICS™ standard forend features an integrated Arca Swiss® rail for use of various commonly available bipod and tripod solutions. The SICS™ can also be fitted with different length forends depending on user requirements.
With all SICS™ forends, a short Picatinny Gen2 rail is included so that a bipod or other 3rd party accessories can be attached to the chassis.
Bag Riders
The Folding Stock Assembly includes a fixed height exchangeable bag rider which features Spuhr Interfaces™ on the bottom surface, for attachment of butt spikes, and other accessories.
Stability features:
The third key feature of SICS™ is stability. SPUHR could have called this precision, but the chassis is not about precision per se, that is the job of the barrel and action. The SICS™ chassis provides extreme stability and stiffness. The foundation for a superiorly accurate rifle system is a rigid platform for the barreled action.
Chassis Body
The SICS™ is based around a rigid chassis body machined from a single billet of 7000 series aircraft aluminum with an extended tenon to support the forend. The exterior sides of the magwell area of the chassis body feature Spuhr Interfaces™ for easy attachment of accessories.
Forend
The Modular Forend, attached to the chassis body with nine M6 fasteners, is machined from a single piece of aircraft aluminum in a tubular design to increase rigidity and stability.
Folding Stock Assembly 
The Folding Stock Assembly features an adjustable locking mechanism to ensure a rock-solid lockup.
Innovation and quality features:
LOP
The Spuhr Ideal Chassis System™ features an innovative patent pending length-of-pull adjustment mechanism, allowing the Folding Stock Assembly to be quickly extended or retracted as needed.
Forend
Not only does the SICS™ Forend feature an integrated Arca Swiss® rail, but it also features an innovative design by which their proprietary Arca Rail Grabber can be rapidly – and securely – moved between positions along the rail, with just a mere push of a button.
Quality
Quality is not just nice to have – it is essential. Sportsmen and professional users alike need to be able to count on their SICS™ being there for them and that it performs every time and under any conditions. Competitions and real-life use can be rough on the gear, and failures can cost more than just a place on a podium. This is why quality and durability are the starting points for every product they design at Spuhr®.
Spuhr® brings world leading level of quality and attention to detail to the development and production of the Spuhr Ideal Chassis System™. Combined with ISO certified production techniques and quality management, the innovative design of the SICS™ will take the shooting experience to the next level.

Accessories:
SPUHR's revolutionary design allows the use of various accessories such as internal and external weights, Picatinny Rails, and ARCA Rail Grabber. The SPUHR ideal Chassis Systems have interface surfaces directly built on the chassis, thus making it possible to mount accessories either by ARCA, Picatinny rails or as direct interfaces for certain accessories such as cartridge Holders, DOPE Card holders and weights. CORETAC SOLUTIONS carries a selection of interfaces for popular accessories.
