The American Rifle Company M-Brace takes everything that made ARC's long-running M10 rings a favorite and rolls it into a single, rock-solid one-piece mount. This version runs a 34mm ring for 34mm scope tubes, a 1.26" (32mm) height, and 30 MOA of built-in elevation cant, which is a smart pick if you're reaching way out and want to keep plenty of turret travel in reserve. The whole thing is CNC machined from high-strength 7075 aluminum and anodized for a tough matte black finish that shrugs off weather and holds up round after round.
Most mounts make you criss-cross torque a handful of ring cap screws while babysitting the scope so it doesn't twist. The M-Brace uses a clamshell-style ring that drops over the tube and clamps with a single set of screws, so the reticle stays exactly where you set it. That no-roll installation is a big reason folks who've run everything from Spuhr to MDT keep coming back to this one. It grips hard enough to handle heavy recoil without marring the tube, and the design is built to return to zero if you ever pull the scope and put it back on.
One of the standout touches is the serrated accessory block, inspired by Hirth couplings used in gas turbines and precision machine tools. Those serrations lock accessories in place so they won't walk under recoil. The included multi-position bubble level mounts right to the grooves, and if you run an ARC LRF mount or a scope bridge for a mini red dot, it all ties in cleanly and stays aligned.
It's designed for Picatinny (MIL-STD-1913) rails and the rail interface is machined to engage correctly even on rails that run a hair out of spec. Torque the scope clamp and rail screws to 55 in-lbs and the bubble level screw to 30 in-lbs, and you're good to go. At roughly 10.7 ounces it's a touch heavier than some competitors, but that weight comes from the beefy, over-built construction people love about ARC gear.
This mount is built for scopes with a 34mm main tube. The ring height is 1.26" (32mm), measured from the optical centerline to the top of the rail, which works well for most mid-sized to larger objective scopes. If you're unsure about clearance, ARC's penny-stack height method is a handy way to confirm fit before you buy.
The 30 MOA of built-in elevation cant angles the scope downward relative to the bore, which gives you more usable turret travel for long-range shooting. If you're dialing dope for distance with magnum or precision loads, that extra elevation keeps you from running out of adjustment. For general-purpose or closer-range use, the 0 MOA option is a better match.
Yes, return-to-zero is one of the things ARC engineered this mount around. Because the clamshell rings don't roll or twist the scope during installation, the tube stays torsionally relaxed and re-engages the rail cleanly. Users swapping between rifles or pulling scopes for travel consistently report solid return-to-zero performance.
That's one of its best features. The serrated accessory interface machined into the mount body locks add-ons in place so they won't shift under recoil. The included multi-position bubble level attaches to those grooves, and ARC's LRF mount and scope bridge tie in the same way for a mini red dot or ranging unit.
