MDT ACC PREMIER GEN2 | RUGER AMERICAN RIMFIRE | FOLDING | BLACK
A Competition Chassis for the Ruger American Rimfire.
The MDT ACC Premier Gen2 Folding Chassis 116079-BLK brings the competition-oriented ACC platform to the Ruger American Rimfire. With a rigid 15-inch forend, integrated ARCA interface, adjustable ergonomics and a folding buttstock, it turns a capable rimfire action into a purpose-built setup for NRL22, PRS-style rimfire and positional shooting. This right-hand configuration is finished in Black.
Ruger American Rimfire shooters have historically had fewer high-end chassis choices than CZ 457 owners. That's what makes this ACC Premier Gen2 noteworthy. Instead of trying to build a match rifle around a conventional stock, you start with the same competition-focused architecture MDT uses across its ACC family: a long, rigid forend, room to balance the rifle, a repeatable support-hand position and a full-length ARCA mounting surface. The result is a rimfire build that works from a barricade, rear bag, bipod or tripod without changing platforms.
Control at the Barricade. Balance on the Clock.
The 15-inch ACC Gen2 forend provides a substantial support surface, integrated barricade stops and mounting positions for M-LOK accessories. ARCA makes it easy to move a compatible bipod along the underside instead of being locked to one attachment point. The V-block bedding geometry supports consistent action positioning, while the adjustable cheek riser, length of pull and vertical grip help you settle into the same position for every shot. A folding buttstock makes the complete rifle easier to transport without giving up a competition-style stock system.
Set the Balance. Find Your Position.
The ACC Premier Gen2 gives you the foundation of a competition rimfire rifle; the right accessories let you tune how it feels from one position to the next. Add MDT ACC Gen2 interior weights to adjust balance within the forend, or use our Pete’s Pillars M-LOK forend weights to place additional mass where you need it. An MDT adjustable thumb rest can help establish a more consistent support-hand position. For a matching Black finish up front, consider the MDT Control Bridge or Night Vision Bridge, depending on the setup you want. Check bridge compatibility with the ACC Premier Gen2 before ordering; all accessories are sold separately.
Our Take
Tune the Rifle You Have, Not the Rifle on Paper.
A long ARCA-equipped chassis is only part of a competition setup. Barrel weight, optic choice and bipod position all affect where the rifle settles. Our USA-made M-LOK forend weights, including the PPFWS family, let you add weight outside the chassis in practical increments; MDT's ACC Gen2 interior kit keeps the additional mass inside the forend. Our PPRS accessory line is another part of the Pete's Pillars catalog; verify its current replacement listing and fitment as part numbers change. Start with the balance you want and adjust from there, instead of buying accessories just to fill every slot.

Frequently Asked Questions
Ruger American Rimfire fitment, ACC Gen2 accessories and the finished competition setup.
Is this the Ruger American Rimfire or centerfire chassis?
This listing is for the Ruger American Rimfire in a right-hand configuration. Ruger American centerfire short-action and long-action chassis are separate inlets; do not assume they interchange.
Does the chassis include the folding buttstock?
Yes. This listing is for the folding ACC Premier Gen2 configuration. The rifle, optic, bipod, weights and other accessories are not included.
Can I mount a Ckye-Pod or GRND-POD directly to the chassis?
The chassis has an integrated ARCA interface. Choose an ARCA/RRS-compatible version of the bipod, such as the Ckye-Pod Gen3 Compact ARCA/Picatinny or an ARCA-equipped GRND-POD. Other attachment versions can require a separate adapter.
Will MDT ACC Gen2 interior weights fit?
The ACC Premier Gen2 supports its designated internal forend weight system. We carry the MDT 110007-BLK four-pack. Confirm the current MDT fitment notes and available clearance for your particular configuration.
What about Pete’s Pillars PPFWS and other M-LOK weights?
Our PPFWS exterior forend weights attach at standard M-LOK positions with adequate clearance. We also offer additional chassis accessories, including our PPRS line, where appropriate for the specific setup. Product identifiers may change as our line evolves; confirm the latest listing before ordering.
What is the difference between 107250 and 107251?
107250 identifies the ACC-family control bridge, intended for an over-forend hand position and barrel coverage. 107251 identifies the night-vision bridge, which provides an upper Picatinny mounting interface. These are distinct products, with color variants. For matching FDE finishes, see: the 107250-BLK Control Bridge and 107251-BLK Night Vision Bridge. Confirm current ACC Premier Gen2 mounting compatibility before ordering.
Can I use the same accessories on other ACC chassis?
Many ARCA and standard M-LOK accessories can move between suitably equipped chassis. Interior weight kits, bridges and other model-specific accessories are different: always verify the exact chassis generation and product fitment.
Where can I find other Ruger American Rimfire options?
Visit our chassis accessories and bipod collections for compatible finishing components. For other rifle platforms, we also carry MDT chassis, precision parts and accessories.
