American Defense ADM4 Mod 2 11.5" SBR - Used

Note: This is a used firearm and will show signs of wear.

The American Defense ADM4 Mod 2 is the flagship SBR in the ADM lineup, built for shooters who need dependable ambidextrous controls in a shorter package. Built around a hand-lapped Criterion barrel, this short barreled rifle delivers precision alongside true ambi function.

The ADM4 Mod 2 is American Defense Manufacturing's flagship short barreled rifle built on a billet AR-15 platform.

Fully ambidextrous controls let shooters run the bolt catch, release lever, and magazine release from either side while maintaining a firing grip. A Geissele G2S trigger delivers a clean, consistent break, and the 11.5" .223 Wylde, 1:8 twist Criterion barrel is hand-lapped and nitrided for accuracy and longevity. A Magpul MOE carbine stock and Raptor ambidextrous charging handle round out the ergonomics.

This SBR ships with an ADM HD buffer, QD endplate, and A2 flash hider already installed, giving builders a complete, ready-to-run short rifle.

Aircraft-grade billet upper and lower receivers are finished in a hard coat Type III MIL-SPEC anodized or Cerakote finish for long-term durability, and the complete rifle weighs 5.9 lbs unloaded.

This rifle is built for duty use, competition, or any application where a compact, precise SBR with true ambidextrous controls matters most.

American Defense Manufacturing builds its rifles in the USA with a focus on patented ambidextrous systems and precision-fit components.
