The Maxim Defense DS-K 7.62mm suppressor is the short, direct thread member of Maxim’s DS series in .30 caliber (Maxim Defense part no. MXM-48082). It uses Maxim’s M-Kore technology inside a Grade 9 titanium tube over a 17-4 stainless steel core. The K length keeps a 7.62mm rifle handier than a full-size can, which suits a shooter running a compact .308 or 7.62 NATO build. Maxim says the DS series differs from the DSX in dropping the secondary tube retention ring and using a Grade 9 tube in place of Grade 5.

Key Specifications

• The caliber rating is 7.62mm (.30 caliber), for 7.62 NATO and .308 class rifles.
• The mount is direct thread, so the can threads straight onto a matching muzzle.
• The tube is Grade 9 titanium over a 17-4 stainless steel core, the pairing used across the DS series.
• Outer diameter is 1.75 inches, the standard DS series tube width.
• The finish is black, matching most rifle builds.
• Maxim rates the DS series full-auto on barrels of 10.3 inches and longer, the minimum it recommends for the line.
