Angstadt Arms
The Angstadt HUB 1/2×28 Booster Assembly is a complete Nielsen device that bridges Angstadt's proprietary HUB suppressor platform to standard 1/2×28 threaded pistol barrels. If you're running a HUB-compatible suppressor on a modern autoloader—especially one with a tilting or short-recoil design—this booster transforms your setup from single-host to truly versatile. It's the connector that lets you take a suppressor designed for one mounting standard and thread it directly onto 1/2×28 pistols without compromise, ensuring your can cycles properly and performs consistently across different platforms.
What makes this assembly complete is what's in the box: the booster unit itself, a Nielsen piston, the spring mechanism, and an O-ring seal. That's everything you need to install and run it. The engineering here is straightforward and proven—the piston harvests energy from the barrel's motion to cycle the booster, maintaining the back-pressure and timing your suppressor needs to function reliably on guns where the barrel moves. No guessing whether it'll work on your Glock, your 1911, your AR pistol, or your 9mm subgun; the 1/2×28 thread is the universal standard for compact pistol cans, and Angstadt's HUB-to-1/2×28 adapter handles the conversion without sacrificing durability or repeatability.
Angstadt Arms manufactures this in the USA, which means you're not gambling on fit or finish. The HUB platform itself was engineered to support serious suppressors—modular, durable, and designed to work hard. This booster assembly is the key that unlocks HUB suppressor compatibility on your 1/2×28 threaded pistols, whether you're shooting indoors, hunting, or running precision drills at the range.
| Thread Pattern | 1/2×28 |
| Base Type | HUB (1.375×24 TPI) |
| Device Type | Nielsen Booster Assembly |
| Includes | Booster unit, piston, spring, O-ring |
| Manufactured | USA |
Yes—this booster assembly is specifically designed for any suppressor with a 1.375×24 TPI HUB base. It converts that proprietary mount to a 1/2×28 threaded interface so you can use it on standard pistol barrels.
Any pistol with a standard 1/2×28 threaded barrel, including Glocks, 1911s, AR pistols, 9mm submachine guns, and other platforms that use that thread pattern.
The booster assembly includes the complete Nielsen device with piston, spring, and O-ring. Installation involves threading the assembly onto your barrel and attaching your HUB suppressor to the rear.
Tilting and short-recoil pistol actions need the energy harvested by a Nielsen booster to cycle reliably. The piston absorbs recoil movement and maintains proper back-pressure, ensuring your suppressor and firearm function consistently together.
