The B&T Firearms SD-ADPA2HUB NATO A2 Hub Adapter is a precision attachment interface designed for shooters who run HUB-compatible suppressors on modern tactical or hunting rifles. This stainless-steel adapter bridges your NATO-specification A2 flash hider to any suppressor built on the industry-standard 1.375x24 TPI HUB thread pattern—the same modular system trusted by armed forces worldwide. If you're consolidating your suppressor collection across multiple uppers or swapping barrels without changing your can, this adapter gives you that flexibility without losing a permanent installation.
The HUB design relies on a gate-lock ratchet system that delivers redundant mechanical security: you simply thread it into your suppressor, snug it down with a spanner wrench, and lock it in place. For users who want semi-permanent duty, it accepts thread-locking compounds like Rocksett. The stainless-steel construction resists corrosion even in hard use, and the NATO-standard A2 interface means compatibility with every modern rifle in your safe—5.56 or 7.62.
This is an adapter device only; it requires both a compatible HUB-threaded suppressor and a NATO A2 flash hider to function. Think of it as the missing link between your existing suppressors and barrels that don't already wear HUB hubs.
