American Defense Manufacturing Ad-170 Base Mount Standard Lever Black

The American Defense Manufacturing AD-170 base mount is a precision-engineered weapons light mounting solution built around a modular platform. Whether you're adding a Surefire 951-type light to your rifle or tower or expanding into other mounting configurations, this base delivers the solid foundation serious shooters and tactical operators need. Machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize, it's built tough enough for professional use and rugged field conditions.

What sets the AD-170 apart is American Defense Manufacturing's patented QD Auto Lock Lever system. This isn't just marketing language—it's a real mechanical advantage. The lever accommodates both in-spec and out-of-spec Picatinny rail systems, meaning you get reliable mounting on rifles with tighter or looser tolerances without fumbling with adapters or workarounds. The QD quick-disconnect design lets you swap your light or accessories without disassembly.

The modular design is the real story here. Standalone, the AD-170 functions as your Surefire 951-compatible light mount. But it also accepts various risers, opening the door to different setups and applications depending on your mission—whether that's a low-power optic riser, a higher-magnification scope stack, or something else down the line. It's the kind of thoughtful engineering that saves you money and hassle later.

Built in the USA and finished to military specifications, the AD-170 is made for people who don't cut corners on their gear. If you run a modern tactical rifle, hunt with a rail-mounted light, or simply want a bulletproof mounting foundation, this is a no-compromise choice.
