OTTER CREEK LABS INFINITY 7.62 SUPPRESSOR - MULTI-CALIBER RIFLE SILENCER, 5.56 THROUGH 7.62MM

The Otter Creek Labs Infinity is a 7.62 suppressor built from DMLS 3D-printed Inconel 718, covering calibers from 5.56 and 6mm through 6.5mm, 7mm, 7.62mm, and subsonic 300 Blackout. At 6.5 inches and 20 ounces without a mount, the Infinity uses a four-chamber design with three interchangeable end caps to dial in backpressure for your specific host platform. The rear is threaded 1.375x24 HUB, compatible with virtually every quick-detach and direct-thread mounting system on the market. The Infinity is full-auto rated with no barrel length restrictions on magazine-fed firearms, and belt-fed capable up to 300 rounds continuous on 5.56 or 200 rounds on 7.62 before cooldown. If you are looking for a precision-manufactured, backpressure-adjustable multi-caliber suppressor built from aerospace alloy, the Infinity is the can. 

The three included end caps give you control over how the Infinity interacts with your host. The solid 5.56 cap maximizes sound suppression for 5.56 rifles and 6mm/243 bolt guns. The vented 7.62 cap dumps the most gas, making it the right choice for notoriously gas-sensitive platforms like the MCX, SCAR, AR-10, Tavor, AK, and overgassed AR-15 builds. The solid 7.62 cap splits the difference, covering standard 5.56 rifles, larger bolt guns in 6.5mm through 7.62mm, and subsonic 300 Blackout. A vented 5.56 cap is also available separately for edge cases that fall between the included settings. 

 

CAPITOL ARMORY'S OPINION

Most suppressors give you one fixed setup and call it done. The Infinity takes a different approach.  It is made from DMLS 3D-printed Inconel 718, features a four-chamber low-backpressure design, with a swappable endcap system tops it off. That last part matters more than many realize. Running a suppressor on a gas-sensitive platform without accounting for backpressure is how you end up with reliability issues and a face full of carbon. The Infinity gives you three calibrated settings out of the box and a fourth available separately. The 1.375x24 HUB mounting solution lets shoots utilize nearly any popular mounting system based on their needs. If you are running a suppressor across multiple platforms and need backpressure flexibility without buying multiple cans, the Infinity is here.

INFINITY AND BEYOND

The Otter Creek Labs Infinity is built for durability, adaptability, and long-term performance. To reduce costs, it’s sold without a mount, instead featuring a universal 1.375×24 HUB-threaded system compatible with a wide range of mounts. Customers can select their preferred option, suiting their own specific use-case and preferences.  

Designed for lower back-pressure performance, the Infinity balances sound suppression and reduces gas blowback. Optimized for 7.62 bore but excelling with 5.56 rifles, it underwent two years of refinement across 100+ prototypes. Its four-chamber design ensures efficient gas flow and offers three included end caps to customize back pressure: the solid 5.56 cap for maximum suppression, the vented 7.62 cap for minimal back pressure, and the solid 7.62 cap for a balanced option. A vented 5.56 cap is available separately for niche needs.

Made from 3D-printed, heat-treated 718 Inconel, the Infinity is tough enough for extreme use, with no barrel length restrictions and high endurance for firing schedules. While slightly heavier than some suppressors, it prioritizes performance and reliability. The Infinity is a versatile, durable suppressor designed to meet the needs of any firearm or user preference.
