Del-Ton's Echo 316 in .300 Blackout extends their value-oriented lineup to the suppressor-friendly cartridge. The 16-inch barrel is designed for supersonic loads but will cycle most subsonic ammunition with the standard carbine-length gas system. Del-Ton's chrome-lined barrel construction is carried over from their 5.56 models, providing the same durability at the .300 BLK price point.
