Improve the Installation Process of Muzzle Devices

Using the Strike Industries 1/2-28 Jam Nut, installing muzzle devices on your AR-15 becomes more accessible and more efficient. By first threading the jam nut on the barrel, then placing the muzzle device on the barrel after it, you have the ability to tighten the jam nut up against the muzzle device to secure it as much as possible.

Often referred to as "jamming" the muzzle device into its proper place, this simple part makes installation much more effective. Jam nuts are particularly useful in situations wherein you are timing your muzzle device.

Good Value

These Strike Industries jam nuts are a low-cost part for your AR-15, and they are reusable, making them an incredibly affordable purchase.

Made to Last

Made from durable AISI 1144 steel and finished via the QPQ (quench polish quench) method, this 1/2-28 Jam Nut is made to last.
