A modular 12 Gauge suppressor that can be configured by hand while in the field.


The SEG12 brings a new and radical concept to the shotgun world. No special tools, just a good solid grip, and you can reconfigure, or clean the suppressor in the field. No rods, no screws, no problem. Half of the 8 aluminum baffles have a patent pending 17-4 SS liner that is permanently locked inside the baffle. Simply alternate the baffle arrangement from the back of the can forward, and you have a hearing safe shotgun can. Additionally, there are no shell, load, or barrel length restrictions. This design guides the payload from baffle to baffle. With the help of the RexQD choke system, attaching and detaching the SEG12 only take a few seconds! For now, we are running cylinder bore at 0.730″ for all the baffles. We will offer different end caps with tighter constrictions at a later date. This initial release will include one RexQD Choke Mount in either Win/Moss/Inv or Rem threads. Benelli/Beretta, VEPR, Saiga and other mounts will come out soon!



Please specify in notes section which REXQD choke mount is needed for your order: Win/Moss/Inv or Rem threads. One REXQD mount is included per purchase.
