The Next Chapter in Muzzle Device Innovation
JMAC Customs has officially introduced their groundbreaking 360HD Taper Mount family, representing a comprehensive solution for serious shooters who demand maximum performance from their firearms. This latest addition to the market promises to deliver exceptional versatility across multiple shooting disciplines and applications.

Advanced Evolution of Proven Technology
Building on the RRD Legacy
The 360HD taper mount represents the newest advancement in JMAC Customs' established Recoil Reduction Device (RRD) family of muzzle brakes. This latest iteration addresses the comprehensive needs of today's demanding shooters, incorporating solutions for durability, installation simplicity, recoil management, flash reduction, and superior suppressor compatibility.
Premium Construction and Materials
17-4PH Stainless Steel Foundation
Every 360HD muzzle device is precision-machined from high-grade 17-4ph stainless steel, ensuring exceptional durability for sustained heavy-duty operation in the harshest environmental conditions. This premium material selection guarantees long-term reliability and consistent performance across diverse shooting scenarios.
QPQ Black Nitride Finish
The 360HD features a sophisticated satin QPQ Black Nitride finish that provides enhanced protection against corrosion and erosion while delivering a sleek, professional aesthetic. This advanced coating technology ensures the device maintains its appearance and functionality even under extreme use conditions.
Optimized Performance Characteristics
Versatile Platform Compatibility
While the 360HD demonstrates universal rifle compatibility, its design has been specifically optimized for short-barreled firearms and high-pressure applications. The device operates without barrel length restrictions, ensuring dependable performance and rugged reliability across an extensive range of firearm platforms.
Advanced Port Engineering
The 360HD incorporates a sophisticated graduated port structure that dramatically reduces felt recoil and muzzle flash through more efficient gas redirection. This engineering approach maximizes shooter comfort while maintaining superior muzzle control during rapid-fire sequences.

Suppressor Integration Excellence
Enhanced Suppressor Protection
The device features three strategically placed sacrificial baffles designed to optimize suppressed performance while minimizing wear on your suppressor system. This thoughtful design significantly extends silencer lifespan and maintains consistent sound reduction over extended use periods.
Superior Taper Mount Design
The taper mount configuration is widely recognized for providing exceptional concentricity and reduced maintenance requirements compared to traditional mounting systems. This design creates a robust friction seal that effectively minimizes gas leakage and prevents suppressor backing-off during intensive shooting sessions.
Installation and Maintenance Advantages
Simplified Installation Process
Gone are the days of specialized armorer's tools – the 360HD requires only a standard 3/4" socket wrench for secure installation on your rifle. This user-friendly approach streamlines the setup process and eliminates the need for additional specialized equipment.
Broad Compatibility Standards
Universal Suppressor Integration
The JMAC Customs 360HD offers seamless compatibility with widely available suppressor systems, including any 1.375-24 Hub device when paired with a JMAC Low Profile Taper Mount HUB Adapter. This broad compatibility ensures shooters can integrate the device with their existing suppressor investments.
Comprehensive Thread Options
360HD muzzle devices are manufactured in multiple thread pitches to accommodate popular domestic and international firearm platforms, ensuring proper fitment across diverse rifle configurations.
Pricing and Availability
The JMAC Customs 360HD carries an MSRP of $119.95, positioning it as a premium yet accessible solution for shooters seeking professional-grade muzzle device performance.
