Description
MDT built the ACC Premier its reputation on the PRS circuit, and the Gen2 brings that same competition DNA to the Ruger American Rimfire in a right-hand configuration. It's a serious upgrade for anyone who wants their rimfire rifle to behave like a full-size precision build, borrowing the stiffer forend, taller barricade stop, and refined ergonomics that MDT rolled out with the higher-end ACC Elite. The whole thing is machined from hard anodized 6061 aluminum and finished in Flat Dark Earth Cerakote, so it looks as good as it shoots.
What the ACC Premier Gen2 Brings to a Rimfire Build
The forend runs a compact 15 inches, which is a smart move for rimfire competition where shorter barrels are the norm. It's wide, thick, and flat, which kills flex and torsion so you get a rock-solid platform on barricades and PRS props. A full-length integrated ARCA rail lets you slide bipods and tripods anywhere you need them, and there are drilled holes up top for MDT's NV and Control Bridge accessories. If you shoot positional stages, the integrated thumb shelf and tall barricade stop earn their keep fast.
Dialing In the Fit on Your ACC Premier Gen2
Comfort and repeatability come down to fit, and this chassis gives you plenty to work with. The included MDT SRS-X Lite buttstock adjusts length of pull through spacers and offers an adjustable cheek riser, so you can lock in a consistent cheek weld shot after shot. It also carries an ambidextrous mag latch, a hole in the trigger guard to reach your trigger weight adjustment, and an M-LOK slot under the buttstock. The included MDT Premier Vertical Grip lets you fine-tune hand position for a natural, repeatable hold.
Installation is refreshingly simple. Drop your Ruger American Rimfire action into the V-block bedding, snug down two screws, and you're set with no gunsmithing required. The V-block keeps consistent contact between the action and chassis, which is a big part of why these systems shoot so well. Add interior forend weights when you want to tune balance for faster transitions and steadier holds. It runs AICS-pattern magazines too, so feeding a match is easy.
