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.

PROFESSIONAL INSTALLATION RECOMMENDED
- Shouldermount muzzle devices index against the shoulder of the barrel
- Facemount muzzle devices index against the face of the muzzle of the barrel
- If using shims with facemount devices, you must use an alignment rod to ensure the facemount shims do not make contact with the projectile exiting the muzzle.
- 30-40ft/lbs of torque along with Rocksett applied to the threads is recommended.
- Improper installation may result in damage to the device and/or the suppressor as well as potential injury to the user.
