JMac Customs 360 Keymount (KeyMicro) Brake

Description

The JMac Customs 360 Keymount (KeyMicro) Brake is unlike others on the market today. This device vents gasses 360 degrees away from your muzzle requiring less effort from the shooter to manage recoil. The use of additional, smaller ports, allows the gasses to disperse in a less concentrated pattern which reduces flash and concussion when compared to a standard muzzle brake. Due to the 360 design, this device does not require timing which makes installation much more simple and does not require shims or crush washer.

*Can be permanently attached to a 14.5″ barrel to achieve 16″ OAL.

What makes the 360 unique?

• 3 layers of protection for your suppressor
• No timing / shims not required
• Lightweight
• Minimal added length
• Compatible with dozens of suppressors
• Reduced Recoil

Specifications:

• 2.050″ long (adds approx 1.45″)
• 10mm Bore (except where noted)
• KeyMount and KeyMicro Compatible
• 17-4ph Stainless
• Black Nitride
• *Not intended or recommend for barrels shorter than 10.5” (see below) 

*When testing these devices, we found that high rates of fire such as full auto or “mag dumps” could cause damage to the device due to the excess heat, pressure, and gasses from unburnt powder on shorter barrels.
