The Disruptor in Black — With the OOPS One Piece Selector

The Triggered Company Disruptor FRT in Black, paired with the OOPS — Original One Piece Selector. The same patented drop-in forced reset trigger that made the Disruptor the top-rated FRT for AR-15 — now with the mil-spec selector feel that shooters have been asking for.

For nearly 70 years, the M16 safety has served civilian and service member alike. The Triggered Company heard the demand for a mil-spec style one-piece selector — and answered. Externally, the OOPS is as close to a mil-spec selector as possible. Whether it serves your nostalgia, your muscle memory, or your cloner build — this is the classic feel on the most proven FRT on the market.

Tactical Tactile Clickyness™ — The Triggered Company's exclusive detent design. No screws to loosen. No levers to get lost. Guaranteed to remind you of your time in the service, your first rifle, or the feel you missed.

Bundle Price $299.99 — Black Disruptor $324.99 — Black Disruptor Ambi

Required Hardware

  • M16-profile BCG — required for reliable reset. Shop MPI Nickel Boron M16 BCG — $159.99
  • H2 buffer minimum — H3 recommended. Shop Odin Works HFRT — $79.99 · Armaspec SMB H3 — $59.99
The #1 cause of FRT failures is incorrect buffer weight — not the trigger. A standard carbine buffer cycles too fast for any forced reset trigger to reset reliably. See our troubleshooting guide if you're having issues.
