Description
The 360HD is the latest evolution in JMac Customs™ RRD™ family of muzzle brakes, designed to meet the needs of serious shooters and professionals alike. Built with durability, ease of installation, and optimal performance in mind, the 360HD delivers unparalleled recoil management and flash suppression while providing maximum protection for your suppressor.
Key Features:
1. Reinforced for Heavy Duty Use:
Constructed from 17-4ph stainless steel, the 360HD is built to withstand the rigors of heavy use. Its satin QPQ Black Nitride finish not only enhances corrosion and erosion resistance but also adds a sleek, professional look to your firearm.
2. Graduated Port Design:
The innovative port structure efficiently redirects gases to significantly reduce felt recoil and flash.
Designed with three sacrificial baffles, the 360HD provides superior protection for your suppressor, extending its lifespan.
3. No Timing Required:
The 360HD eliminates the hassle of timing and shims, allowing for quick and straightforward installation. Simply use standard tools: 3/4" socket wrench
4. Rugged and Reliable:
Designed with no barrel length restrictions, the 360HD is optimized for short-barreled firearms and high-pressure applications, ensuring consistent performance across a variety of platforms. Its durable build and unique graduated port design reflect JMac Customs'™ commitment to engineering excellence.
5. Multi-Functional Performance:
Whether you’re running suppressed or unsuppressed, the 360HD offers outstanding versatility:
- Suppressor Protection: Three sacrificial baffles safeguard your suppressor from gas erosion.
- Recoil Management: Exceptional muzzle brake performance reduces felt recoil and improves shooting control when firing unsuppressed.
