Length compared against the 628 .30 Cal / 7.62mm suppressors in the catalog that publish one. Quartile basis; a value inside the middle half carries no note.

- Base interface
- Direct Thread (multiple)
This suppressor threads straight onto the barrel, so no mount is required. 13 mounts in our catalog are thread adapters that let it run on other barrel threads.

Check in the BuilderThe Thunder Beast Silencer Summit fires every suppressor entered on the same gun, with the same equipment. Chisholm was measured in 3 tests. Figures can only be compared with others from the same test, so each one links to everything else fired on that gun.

Manufacturer claim
- Rather than using a traditional stacked and welded baffle system, the design is based on a monolithic core to improve structural integrity and reduce operational limitations.
- The core geometry also reduces back pressure compared to many traditional baffle designs, which can decrease carbon buildup.
- All suppressors are user-serviceable and can be disassembled for cleaning using optional service kits that include a mounting base and spanner wrench. No specialized chemicals are required for maintenance.
- The Slim Core Series forms the foundation of North Country Armory's mono core suppressor lineup. With a 1.5-inch diameter, these suppressors offer a lighter, more compact option for shooters seeking effective suppression in a smaller package.

- After testing multiple configurations, a slot-and-pocket-style mono core was selected. The core is manufactured from titanium due to its high strength-to-weight ratio, allowing the suppressor to remain lightweight while maximizing strength and longevity, all while maintaining excellent sound suppression.
- In the event of a baffle strike, the suppressor is less likely to experience catastrophic failure, as the continuous titanium core structure helps redirect the projectile with limited damage.
- Limited lifetime warranty: North Country Armory warrants to the original purchaser that the suppressor will be free from defects in material and workmanship under normal use and service for the life of the purchaser. The warranty is non-transferable and does not cover misuse, unauthorized modifications, normal wear, improper installation, an improperly threaded barrel, or reloaded or non-standard ammunition.
- Headquartered in Gillette, Wyoming, with an additional location in Havre, Montana, we design and machine every suppressor in house. North Country Armory is proud to build American-made suppressors for sportsmen and shooting enthusiasts.
- This series maintains strong sound suppression while delivering the durability and accuracy that define North Country Armory products. The Slim Core Series is well suited for users who prioritize reduced size and weight without sacrificing performance.
- The mono core allows compatibility with nearly all SAMMI-spec cartridges and eliminates barrel length restrictions, except for certain high-powered .30 caliber applications.
- Service manual: the baffle core threads out of the suppressor tube and is torqued to 30 lb/ft on reassembly. DO NOT attempt to remove the thread adapter from the tube — removing it may cause irreversible damage to the tube or thread adapter, and such damage will void your warranty.
