What Does a Muzzle Brake Do?

A muzzle brake redirects the gases from the end of the barrel through ports, reducing the overall felt recoil when you fire a shot. This also reduces the report from the muzzle, dampening the sound and flash from the end of the barrel. Overall, installing a muzzle brake makes you more accurate and the shooting experience more enjoyable.

Do All JMac Customs Parts Work for All AKs?

The short answer is no. While some AK parts are interchangeable between different models, a large majority are not. When purchasing parts for your firearm, make sure you get one that is specifically designed for your exact model and caliber. Otherwise, the part may not fit properly and could cause malfunctions or other issues.

Do You Need a Gunsmith to Install a Muzzle Device?

No, you can install a muzzle device yourself at home. However, if your firearm has an existing muzzle device that is welded on, you will need to install a new barrel first. Additionally, if you have a shorter barrel and need to add a muzzle device to the end to make it at least 16 inches in length, you may need help from a gunsmith to pin or weld the muzzle device in place.
