Fatboy Tripods Arca Plate M-Lok
The Fatboy Tripods Arca Plate M-Lok is a precision rifle and optic mounting solution built to connect your favorite precision gear to Arca-Swiss tripod clamps. Designed and manufactured in the USA, this M-Lok rail adapter bridges the gap between modern tactical rifle accessories and traditional tripod support—a clean, direct path to rock-solid stability for long-range hunting, precision shooting, or glassing sessions. If you're running M-Lok slots on your rifle or spotting scope cage, this plate gives you the versatility to lock into any Arca-compatible tripod head without adapters or workarounds.
Fatboy Tripods built this mount from quality materials with the kind of attention to detail you expect from a US-made accessory. The machined design is straightforward: slide your M-Lok equipment onto the Arca rail, tighten it down, then clamp the whole assembly into your 1.5/38mm Arca-Swiss tripod head. It's the kind of simple, reliable connection that keeps your scope or rifle steady when precision matters—whether you're dialing in at the range, hunting from a rest, or surveying terrain from a glassing knob.
This M-Lok plate is purpose-built for hunters, long-range shooters, and overlanders who already invest in Arca-Swiss tripod systems and want a seamless way to mount modern gear. No fumbling between rail standards, no proprietary clamps—just solid American engineering that plays well with the equipment you already own.
