Why You Need It
A quality jam nut is essential for proper muzzle device installation. It locks your brake or flash hider in place, ensuring consistent performance and preventing the frustration of devices that shift or loosen during shooting sessions. This is particularly important if you're running a precision rifle or a high-round-count training gun.
Installation
The jam nut threads onto your barrel before installation of the muzzle device, then is tightened against the device to create a secure, permanent fit. This is standard practice among experienced shooters and gunsmiths.
