You should be able to remove the flash suppressor from a 715t without any issues. There are a few ways to do this, but the most straightforward way is to use a vice and a torque wrench.
First, locate the set screws on the flash suppressor (typically two or three). Once you have found them, use the torque wrench to loosen them until they are no longer tightened.
Next, place the 715t in the vice so that the muzzle is facing upwards. Then, use a punch or another type of blunt tool to drive out the flash suppressor from the front of the barrel.
You may need to use some force to get it started, but it should eventually come out with relative ease. Be careful not to damage the threads on the barrel while removing the suppressor.
Once you have removed the flash suppressor, you can then proceed to install a new one if you so choose. There are a few different types of suppressors available on the market, so be sure to do your research before making a purchase.
