    SICS comes standard with a polymer pistol grip with rubber overmold.

    The chassis accepts any AR15 pistol grip with the exception of grips that have a beaver tail which requires trimming/cutting to fit. Factory grip can be removed by removing the screw from inside the grip like any AR15.





    And it's also adjustable fore and aft via 2 screws.

    Optional weight kits are available in both exterior and interior mounting, 2-pack and 5-pack.

    Exterior weights are secured via the Spuhr interface, interior weights are secured by 3 screws from the bottom of the handguard.

    The chassis, like all Spuhr products, is made of 7075 aluminum and it is optimized for strength and repeatability while cutting any unnecessary weight. This is the reason why it does not feature a magazine cutout on the weak side.

    Feature 2 - The Chassis Body

    The SICS™ Chassis Body is machined from a single billet of 7075 T651 aluminum alloy, and is designed to provide the most rigid cradle possible for the barreled action, as to achieve the highest possible degree of accuracy and precision from the rifle system.

    The first step in the design process was to ensure that the forend attaches in front of the action so that any side forces onto the forend do not spread to the chassis body or to the barreled action.

    The next step was to choose a magazine, where we opted for the tried and true AICS pattern magazine well, thus achieving a stronger chassis body, by using a magazine that locks from the bottom rear than from the side, as well as allowing the user a wider range of sources for magazines than a single brand. (We also offer an extended magazine stop for gunsmith fitting for those who need them.)

    We also extended the sides of the magazine well forward, so that they provide a natural barricade stop without impacting the barreled action or the forend.

    The third step was to fit the chassis body with a comfortable grip. We naturally chose to design the SICS™ Chassis Body to accept most aftermarket AR15 pistol grips, but in the end we opted to design and fit the SICS™ with our own rubberized grip design. To ensure that the pistol grip is as comfortable as possible we made it adjustable, with 8 mm/0.32” of travel, to perfectly align your trigger finger with the trigger.

    Though the pistol grip does not feature a thumb shelf, we have created a natural resting place for the shooting hand above the rear of the pistol grip.

    As a compliment to the QD sling cups on top of the forend, a third QD sling cup is attached to the rear left side of the chassis body.

    Finally, we added Spuhr Interfaces™ to the sides of the mag well, so that cartridge holders and other accessories can be attached there. Also, competition shooters may want to attach accessories such as timers or DOPE card holders, etc., to the rifle even if they chose not to use one of our ISMS™ scope mounts.

    I agree, but to be fair MDT chassis are 6061-T6 while these are 7075-T651.
    I suck at responding to PMs. Don't take it personally.
