MDT ACC Elite Chassis Base (Rem 700 SA)

The MDT ACC Elite Chassis Base is the heart of one of Modular Drive Technologies’ most important competition precision rifle chassis systems.

First showcased in 2023 (as part of the entire ACC Elite Chassis System), the base specifically holds the barreled action. MDT’s design focuses on extreme rigidity, not just in supporting the action but also by making sure that the base is resistant to torsion and stresses that are commonplace in rifle matches.

For this reason, MDT made the 19" forend portion of the ACC Elite Chassis Base wider, thicker, and longer. Besides eliminating any possible flexing, this base also carries a full-length integrated ARCA rail, M-LOK slots, an RRS Lock interface along the bottom, and QD sling cups.

Additionally, the chassis’ balance is tunable with modular interior and exterior forend weights. The top of the forend is drilled and tapped for MDT’s Night Vision Hood or Control Bridge, and an integrated wide barricade stop gives you an aggressive edge for working props. Adjustable M-LOK thumb rests on both sides let you place your firing hand exactly where you want it. The ambidextrous mag latch and magwell are adjustable to remove slop with high-end actions, and there’s space for optional dowels if you want an even tighter magazine fit.

A hole in the trigger guard provides easy access for trigger adjustments. Custom-cut grip tape is included for the underside of the forend, adding texture and a tactile reference point on barricades and bags.
