Description
Some suppressors try to do everything. The Mach-K from Liberty Precision Machine does one thing really well: it keeps a .30 caliber rifle quiet without turning it into a boat anchor. At 5.5 inches bare and 5.65 inches with the included 5/8-24 Rearden DTA Ti direct thread adapter, this can adds barely any length to your rifle, and the all-titanium build keeps the weight down to 7.4 ounces without the mount, 8.2 with it. If you hunt with a shorter barrel or just hate the way a full-size can changes your rifle's balance, this is the kind of suppressor that stays on the gun instead of sitting in the safe.
Anthem 2 DNA in a Titanium Package
The Mach series is the evolution of LPM's original Anthem line, and the Mach-K runs the same refreshed baffle stack as the Anthem 2 series, just machined from titanium. The progressive baffle design and spacing are tuned for the different pressure zones gas moves through inside the can, which is why it handles everything from subsonic 300 Blackout to full-power supersonic .30 cal loads without complaint. The tubeless, fully welded construction means there is no outer tube adding weight or bulk, and the 1.74 inch diameter keeps it slim over most barrel profiles.
Mounting the Mach-K
The rear of the Mach-K is threaded 1.375-24, the industry standard HUB pattern, so you are not locked into one company's mounting ecosystem. Run the included titanium direct thread adapter or swap in a quick-detach mount from the wide range of HUB compatible options on the market. There are no barrel length restrictions on .30 caliber or smaller cartridges, though LPM recommends a muzzle brake on barrels shorter than 14.5 inches to take some of the beating off the blast baffle.
Built to Last, Backed for Life
LPM finishes the Mach-K in Graphite Black Cerakote and marks it with the patented Serial ID Ring, which makes maintenance and future service simpler. It also carries a lifetime warranty against defects in materials and workmanship, so this is a can you buy once and run hard.

Frequently Asked Questions
What calibers can I run through the Mach-K?
The Mach-K is rated for .30 caliber and smaller cartridges with no barrel length restrictions. That covers everything from 300 Blackout and .308 down to 6.5 Creedmoor, 5.56, and other smaller bores. Liberty Precision does recommend running a muzzle brake underneath it on barrels shorter than 14.5 inches.
Is the Mach-K HUB compatible?
Yes. The rear of the can is threaded 1.375-24, which is the industry standard HUB pattern. It ships with a 5/8-24 Rearden DTA Ti direct thread adapter, but you can swap in quick-detach mounts and other adapters from most major suppressor mount makers.
How does the Mach-K compare to the Mach-S and Mach-L?
All three share the same Anthem 2 derived baffle design in titanium, and the difference comes down to length. The Mach-K is the shortest and lightest of the family at 5.5 inches, while the Mach-S and Mach-L trade added length and a few ounces for more sound reduction. Pick the Mach-K when compactness and handling are the priority.
Will the Mach-K hold up on a gas gun, or is it just for bolt actions?
It works fine on both. LPM designed the Mach series with low blowback on gas-operated firearms as one of its core goals, and the fully welded titanium construction is plenty durable for semi-auto use. It also carries a lifetime warranty against defects in materials and workmanship.
