What Is the Partisan Disruptor FRT Trigger?
The Partisan Disruptor is a 3-position forced reset trigger for AR-15 that uses the bolt carrier group’s rearward travel to mechanically reset the trigger after every shot. Instead of waiting for the shooter to manually release the trigger to achieve reset, the BCG pushes the trigger forward during its rearward stroke — completing the reset before the bolt even returns to battery.
The result: a shooter maintaining rearward finger pressure fires at a cyclic rate limited only by the BCG cycle speed — approximately 1,150 RPM in FRT mode. Every shot still requires a separate, deliberate trigger pull. The Partisan Disruptor FRT is not a machine gun, fires one round per trigger function, and is federally legal under the NFA following Garland v. Cargill and the May 2025 DOJ settlement.
Unlike other drop-in FRT triggers for AR-15, the Partisan Disruptor uses a true cassette architecture — the entire trigger assembly (hammer, trigger, disconnector, springs, reset mechanism) is pre-assembled inside the cassette housing. Drop it into your lower, insert the pins, and it runs. No individual spring management, no fitting, no gunsmithing required.

Required Hardware for the Partisan Disruptor FRT
The Partisan Disruptor AR-15 FRT requires two specific hardware components for reliable operation. Installing the trigger without these is the #1 cause of reset failure:
M16-Profile BCG (Required)
The extended carrier tail on an M16-profile BCG provides the contact geometry the Disruptor’s reset lobe needs during the rearward stroke. A standard AR-15 BCG will cause inconsistent resets. Running an M16 BCG in a semi-auto AR-15 is legal in all 50 states.
H2 Buffer Minimum (Required)
A standard carbine buffer cycles too fast for reliable FRT reset timing. H2 (4.6 oz) is the minimum. Our bundle includes an H2.5 (5.1 oz) buffer — the sweet spot for most carbine-length Partisan Disruptor builds.

Frequently Asked Questions — Partisan Disruptor FRT
What is the Partisan Disruptor FRT trigger?
The Partisan Disruptor is a patented drop-in cassette forced reset trigger for AR-15 platforms, manufactured in the USA by Partisan Triggers / The Trigger Company. It uses the bolt carrier group to mechanically reset the trigger after every shot, enabling faster follow-up fire than any standard semi-auto trigger while remaining federally legal.
How much is the Partisan Disruptor FRT?
$299.99 from ARTakedownTool.com — the best authorized dealer price available online. The bundle with M16 BCG and H2.5 buffer is $449.99.
Does the Partisan Disruptor require an M16 BCG?
Yes. An M16-profile BCG is required for reliable reset contact. A standard AR-15 BCG will not work reliably with the Disruptor. Our bundle includes a compatible M16-profile BCG.
Is the Partisan Disruptor the same as the Rare Breed FRT?
No. The Partisan Disruptor and Rare Breed FRT-15 are separate products from competing manufacturers, both covered by independent patents. See our Partisan vs Rare Breed comparison.
