Question 40

Why do some muzzle devices have a barrel length restriction?

Accepted Answer

Some muzzle devices, specifically the LAF, 2C, 4C, and original 360, will have a 10.5” barrel length restriction.

Although rare, when testing these devices with supersonic ammunition, we found that high rates of fire such as full auto or “mag dumps” could cause the device to become damaged due to excess pressure and gasses from unburnt powder on shorter barrels. This is why the barrel length restriction was put in place. There is no issue with subsonic ammunition.

For firearms with barrels shorter than 10.5”, please see our 360HD (Heavy Duty) muzzle device, specifically designed for shorter barrels.

Question 41

Do you offer express or expedited shipping?

Accepted Answer

All orders are shipped via USPS standard parcel post. Package insurance is available during checkout through Route.

Question 42

How do I install KeyMount, KeyMicro, or X-Series muzzle devices?

Accepted Answer

JMac Customs recommends that all suppressor mounts be installed and checked for alignment by a certified professional. Serious damage could result to your suppressor/firearm and physical harm is possible if installed/used incorrectly.

All suppressor mounts MUST be tight against the shoulder or face of the barrel, using shims or face-milling method. Click to contact us if you have any questions or need a recommendation for professional installation. JMac Customs LLC is not liable for injury, damage, or death related to the usage of this product.

JMAC Customs recommends that devices intended to be used with suppressors are installed using Rockset and torqued to 30-40 in/lbs.
