The Comstock Ultralight Recessed mount is a titanium, 1/2-28 threaded suppressor mount built around the .900″-24 Plan-B adapter standard. Because it weighs just 0.7 ounces and adds less than 0.1″ to your muzzle, it’s one of the lightest and most compact QD mounting options available. It’s rotationally symmetric, so there’s no timing or shimming needed at install.

Description
Comstock Armory 1/2×28 Ultralight Recessed Mount
Specifically, the Comstock Ultralight Recessed mount solves a problem that traditional suppressor mounts create: added front-end weight that throws off your rifle’s natural balance. Because it’s machined from Grade 5 titanium and finished with a durable PVD coating, this mount weighs just 0.7 ounces while still holding up to repeated suppressor attachment and removal. The recessed design sits directly over the barrel shoulder, which means it adds less than 0.1 inch to your muzzle length — a meaningful difference when you’re already running a compact host rifle.
In particular, threaded 1/2-28 and built around the .900″-24 adapter standard, the mount pairs with common Plan-B-compatible adapters like the Comstock LPA, Q Plan-B, and Rearden Atlas. Since it’s rotationally symmetric, there’s no timing or shimming required, so installation stays straightforward even for a first-time suppressor host build. Additionally, the 13/16″ wrench flats make removal just as painless as install.

Why This Product Stands Out
Notably, most shooters don’t think about mount weight until they’re holding a suppressed rifle that feels nose-heavy. That’s exactly the gap the Comstock Ultralight Recessed mount closes, because titanium construction shaves ounces without giving up the strength needed for repeated suppressor cycling. In contrast, for a competitive shooter or a home-defense rifle that stays suppressed, that weight savings adds up in a way steel mounts simply can’t match.
Because it’s rotationally symmetric, there’s no fussing with shims or witness marks to get the mount timed correctly — thread it on, torque it down, and you’re done. As a result, installation takes minutes rather than a trip back to the bench. Furthermore, the recessed geometry keeps the added length under a tenth of an inch, so your handling characteristics stay close to what you’re used to running unsuppressed.
Ideal Use Cases
- Suppressor hosts built for minimal added weight and length
- Competitive shooters who need quick suppressor attach/detach between strings
- Home-defense rifles that stay suppressor-ready without adding front-end bulk
- Builders standardizing on the Plan-B / .900″-24 adapter ecosystem
