Subsonic Ammo

What is subsonic ammo? Well, in short, subsonic ammo doesn't break the sound barrier. It is a cartridge that has less energy. The advantage of subsonic rounds is noise reduction when paired with a suppressed firearm. We stock a variety of calibers from subsonic .22lr ammo to 7.62x39. Shop today at your online source for subsonic ammunition, Palmetto State Armory.
