Armaspec Harmonics-Tuner Muzzle Brake 30 Cal 5/8x24 Black

The Armaspec Harmonics-Tuner Muzzle Brake is a precision-engineered, dual-purpose muzzle device that fuses a recoil-reducing muzzle brake with an adjustable barrel tuner in a single unit. Purpose-built for the AR-15 and AR-10 platforms, it cuts recoil while letting the shooter dial in barrel harmonics for tighter, more repeatable group sizes.

This 30 Cal model (ARM1932-BLK) is machined from stainless steel with a durable black finish and threaded 5/8x24. Harmonics tuning is accomplished through a simple hex-screw adjustment at the front of the unit, allowing the shooter to add or subtract mass and shift the barrel's harmonic node for sub-MOA accuracy potential.

Drop-on installation, rugged stainless construction, and a recoil-reducing design make the Armaspec Harmonics-Tuner a smart upgrade for any AR-platform rifle chambered in 30 Cal.
