The Maxim DS-HD 5.56 NATO suppressor is a hard-use rifle can from Maxim’s DS series, closely related to the DSX and built with M-Kore technology (Maxim part no. MXM-48052). Maxim keeps the price down by using a Grade 9 titanium tube instead of Grade 5 and dropping the secondary tube retention ring, while keeping a 17-4 stainless steel core. It is rated for full-auto fire on barrels 10.3 inches and longer. A 1.375-24 HUB mount and a direct thread insert come with it, and the core has integrated carbon cutters. It suits a 5.56 carbine or rifle that will see heavy use.
