Product Description
A-TEC A-SUB 5 – .44/.45 Cal Lever Action Moderator
Designed for Subsonic Performance
The A-TEC A-SUB 5 is a front-mounted moderator engineered specifically for subsonic .44 and .45 caliber rifles. It’s purpose-built to reduce muzzle blast and sound signature while preserving the balance and handling characteristics of classic lever-action rifles.
Lightweight and Compact Construction
Despite its robust performance, the A-SUB 5 remains exceptionally lightweight — weighing only 380 grams. With a total length of 235 mm and a diameter of 49 mm, it offers excellent suppression without adding unnecessary bulk to your rifle. This makes it ideal for extended shooting sessions or hunting trips where agility and control matter.
Optimised for Lever-Action Rifles
The A-SUB 5 is designed to complement Henry, Marlin, and S&W lever-action rifles chambered in .44 Magnum and .45/70. Its front-mount configuration ensures smooth cycling and maintains the rifle’s traditional lines while delivering exceptional sound suppression for subsonic loads.
Superior Noise and Recoil Reduction
Built with a larger internal volume specifically tuned for subsonic ammunition, the A-SUB 5 effectively reduces muzzle report, flash, and felt recoil. This results in a quieter, more controlled shooting experience — perfect for both hunting and target applications in noise-sensitive environments.
Durable, Field-Ready Design
A-TEC’s precision engineering and high-quality materials ensure long-term durability under real-world conditions. The A-SUB 5 is easy to mount, easy to maintain, and designed for consistent performance across a wide range of subsonic loads.
