There are a few ways to do it. You can try using a Heat Gun, hacksaw, or vise.
A heat gun may work if the flash suppressor is made from a soft metal like aluminum. However, if it’s made from a harder metal like steel, you’ll need to use a hacksaw or vise. Start by heating the flash suppressor with the heat gun until it’s red hot. Then use the hacksaw or vise to remove it. Make sure to wear safety goggles and gloves while doing this.
