Science of Suppression
Science of Suppression (SOS) builds suppressors in Queen Creek, Arizona, from 17-4 hardened stainless steel. Every SOS is full-auto rated, has a HUB (1.375x24) rear and comes with a direct thread adapter, and SOS makes some of the most economical suppressors we carry.
Einstein: the 5.56 and 6mm ARC family, from the short Einstein K to the full-size Einstein L. Dark Matter: .30 cal suppressors for .308 and 300 BLK, in the compact Dark Matter K and the full-size Dark Matter L. Multi-caliber: the Nebula 36 for 9mm, 5.56 and .350 Legend, and the big-bore Atom 46 for everything from .45 ACP to 45-70. We carry the Einstein K, Dark Matter K, Dark Matter L and Atom 46, and you can pre-order the Einstein L and Nebula 36 by calling us at 512-879-1068.

MOUNTS AND ACCESSORIES
Every SOS comes with a direct thread adapter: 1/2x28 on the Einstein line and 5/8x24 on the Dark Matter line and Atom 46. Because the rear is HUB (1.375x24), it also takes any HUB mount. For quick-detach, the Plan-B by Q lets you move a can between rifles; for a second 1/2x28 or 5/8x24 adapter, the Diligent Defense Ti Direct Thread Adapter is a light titanium option. For other thread pitches, the SilencerCo Bravo Direct Thread Mount and Dead Air direct thread mounts come in about ten pitches each. Shop all HUB mounts.
