Advantage Arms 1.75x9 338 Lapua Modular QD Black Suppressor

Stainless steel, black finish, and a baffle stack you can add to or subtract from. The Advantage Arms 1.75x9 is a modular rifle can rated up to 338 Lapua, which puts everything from a 223 AR-15 to a magnum bolt gun inside its bore rating. Run it long when you want maximum suppression, pull baffles when you want the rifle back to a manageable length.

It fully disassembles, which is the argument for stainless over a sealed lightweight can. You clean it instead of replacing it, and it will outlast most of the barrels you thread it onto. A quick detach muzzle brake comes with it, so moving the can between rifles means a matching brake on each host rather than a trip to a gunsmith every time the plan changes.
