Description

Comstock Armory Ultralight Recessed 5/8×24 Mount

A Comstock Ultralight Recessed 5/8×24 mount is built for the shooter who wants quick-detach suppressor capability without adding an ounce of unnecessary weight or length to the muzzle. Because it’s machined from Grade 5 titanium rather than steel, this mount shaves front-end weight while still standing up to the abuse of regular suppressor mounting and removal. The recessed design sits back over the barrel shoulder, which means the Comstock Ultralight Recessed 5/8×24 adds less than 0.1 inch to overall length once installed. As a result, shooters running Plan-B or Rearden Atlas suppressor systems get true QD functionality without the bulk that heavier steel mounts typically bring to the table.

Since it interfaces with the same .900″-24 adapter standard used by the Comstock LPA, Q Plan-B, and Rearden Atlas suppressor systems, this mount slots directly into an existing Plan-B-compatible lineup. The rotationally symmetric design means there’s no timing or shimming involved, so installation is simply a matter of threading it onto a 5/8×24 barrel and torquing it down with the included 13/16″ wrench flats.

Additionally, the PVD finish is there for a reason: it resists the corrosion and wear that come from repeated suppressor cycling, which matters for anyone running a can on and off between range trips and field use. Because the mount fits any barrel up to 0.750″ in diameter, it covers most common 5/8×24-threaded rifle barrels without further modification. Consequently, shooters can move this mount between builds sharing that thread pitch without hunting down a separate solution each time.

Why This Product Stands Out

Most suppressor mounts on the market are steel, which means they add weight exactly where a shooter doesn’t want it — out at the muzzle, where every ounce affects handling and balance. Because the Comstock Ultralight Recessed 5/8×24 is machined from titanium instead, it delivers the same strength shooters expect from a mounting solution while keeping the front end light and responsive. That matters whether the rifle is set up for 3-gun, hunting, or a home-defense build that spends most of its life suppressed.

The recessed geometry is just as important as the material. Since the mount sits back over the barrel shoulder rather than protruding forward, it keeps overall system length to an absolute minimum — a real advantage for anyone running a shorter-barreled rifle where every fraction of an inch counts. Furthermore, the lack of required timing or shimming means installation stays simple even for shooters who aren’t set up with a full gunsmithing bench at home.

Ideal Use Cases

• Suppressed 3-gun and competition builds where weight and length matter
• Hunting rifles that need quick suppressor attachment and removal in the field
• Home-defense or duty rifles, since suppressed setups benefit most from lighter muzzle hardware
• Existing Plan-B, Rearden, or Q-compatible suppressor systems needing a lightweight mount option
