Safety Tips
  • Meet in a public, well-lit spot — a police-station safe exchange zone is the best choice.
  • Bring a friend along for high-value deals; avoid meeting alone or after dark.
  • Inspect the item in person before any money changes hands, and never send a deposit to “hold” it.
  • Put the deal on paper — a signed bill of sale protects both sides.
  • Refuse wire transfers, gift cards, and crypto — scammers ask for exactly these.
  • If the price looks too good to be true or the other party rushes you, walk away.

Description

This ultra-compact 12-gauge semi-auto shotgun delivers tactical performance in a maneuverable platform. The gas-operated action cycles reliably with 5+1 capacity, supported by corrosion-resistant internals including a nickel boron-coated gas piston, hammer, and sear. The 14.75-inch blued barrel features a fiber optic front sight and includes a choke tube for versatility. The ergonomically designed grip with rubberized palm pad minimizes felt recoil while the enlarged, beveled loading port with bright orange follower and pinch-free elevator streamlines loading. The integrated Lasersaddle system mounts seamlessly to the receiver with adjustable windage and elevation, featuring multiple touchpad activation points. Additional features include a knurled charging handle, oversized paddle-style bolt release, and M-LOK compatible slots on the magazine tube extension for accessory customization. The ambidextrous safety with red indicator is easily accessible to all shooters. Finished in matte black synthetic furniture, this 27.125-inch platform weighs 6.04 pounds and ships with one tube magazine.
