A forced reset trigger (FRT) mechanically resets the trigger against the shooter's finger as the bolt carrier group cycles. The firearm remains semi-automatic: one trigger function equals one round fired. The difference is that the trigger resets at the speed of the BCG rather than waiting for the shooter to release and re-press.

This allows cyclic rates approaching 1,000-1,200 rounds per minute while maintaining semi-automatic legal status. The shooter still controls each shot: releasing pressure on the trigger stops the firing cycle immediately.

The Partisan Disruptor descends from the original TacCon 3MR trigger design and is covered by US Patent 9146067. It's not a copy of the Rare Breed FRT but rather a distinct implementation of forced reset technology with its own engineering refinements.

The Disruptor uses a cassette-style interface, a design choice that ensures all contact surfaces maintain proper alignment. This eliminates the fitment issues that plague some drop-in trigger designs and makes installation genuinely tool-free for most users.

Heat-treated 4140 chromoly steel and S7 tool steel are used on all wear surfaces. The Triggered Company claims a CMP Service Rifle Match-compliant pull weight of 3.75-4.1 lbs in semi-auto mode with a crisp break and short reset.

Hands-On Impressions

On the launch unit we bought: the semi-auto reset was clean and short, but the break itself was noticeably gritty, worse than a standard milspec trigger. Out of the box it was not something you would choose over a basic milspec FCG for precision work.

The original safety selector was the other rough edge: significantly larger than a standard AR-15 selector, less positive in its detent than milspec, and non-ambidextrous. The 3-position function (Safe/Semi/Enhanced) operated as intended, but the feel was a step down from what most shooters are used to. Both of those complaints have since been addressed, as covered below.

Update (July 2026): The Newer Revision Breaks Like a Two-Stage

The break on the current Disruptor revision is dramatically better than the launch unit. The Triggered Company sent us a newer cassette to evaluate, and in semi-auto it now feels practically like a two-stage trigger: there is a real wall, and the break off that wall is cleanly defined and predictable. That is a different trigger from the one we bought in January, and it removes the biggest reason we told people to buy this strictly for FRT mode.

The take-up ahead of the wall is still very gritty. That is the one complaint that survives the revision. Grit in take-up is typically an engagement-surface finish issue, so a few hundred rounds and a drop of oil on the fire control group should smooth it out, but it is present out of the box and you should expect to feel it on the first range trip.

Update: The SBW Ambi Selector Fixes the Safety Completely

The SBW (Swings Both Ways) selector resolves every complaint we had about the original oversized single-side lever. We ran one, and it feels like a Radian Talon: crisp positive detents in all three positions, a lever profile that indexes naturally under the thumb, and levers on both sides of the lower for support-side and switch-shoulder work. It is the single biggest ergonomic upgrade available for this trigger.

One nitpick: the levers are not keyed, so nothing physically prevents you from installing one backwards. Pay attention at the bench and it is a non-issue.

There are two ways to get it. The Disruptor Ambi SKU ships with the SBW installed for a $25 premium over the standard trigger, which is the one to buy if you have not bought either yet. If you already run a standard Disruptor, the SBW is sold on its own for $29.99.

Update: Mil-Spec Style Selector Now Available (The OOPS, $19.99)

The Triggered Company also addressed the selector complaint from the opposite direction with the OOPS (Original One Piece Selector), a $19.99 mil-spec style one-piece selector designed for the Disruptor and the upcoming LAT trigger. It drops the oversized lever and screws for a fixed, standard M16/M4 form factor with a positive tactile detent. If the factory selector's size and mushy feel were the dealbreaker for you, the OOPS is the fix without buying the ambi SKU.

The Triggered Company subjected the Disruptor to over 6,000 rounds under a course of fire derived from the USMC M27 IAR evaluation criteria. Independent reviewers have confirmed the durability claims with their own extended testing.

In controlled testing, the trigger achieved cyclic rates around 1,150 rounds per minute in FRT mode. A four-target drill (5 rounds per target at 5 yards) showed clear time advantages: 5.9 seconds in semi-auto versus 3.9 seconds in forced reset mode.

The trigger ran reliably across 10 different magazine types including Magpul Gen 2, Gen 3 PMAGs, Lancer, Daniel Defense, Hexmag, Amend 2, and standard GI aluminum magazines. No bolt hang-ups or cycling issues were reported during extended testing.

Compatibility caveat: The trigger did not function reliably in a SIG MCX (light primer strikes) or PSA AR-V 9mm PCC (ejection issues). Standard AR-15 platforms, including both DI and piston systems, ran without issues.

The Partisan Disruptor fits AR-15 pattern lowers with an in-spec mil-spec fire control pocket, and it requires an M16-profile (full-auto) bolt carrier group plus an H2 or H3 buffer. Those three things are the whole compatibility test for most builds. It is not a universal FRT: it is an AR-15 fire control cassette, so any host that does not use an AR-15 fire control group is out regardless of caliber.

9mm AR and PCC hosts

The Disruptor runs in 9mm AR builds when the lower and fire control pocket are in spec, but expect to tune the buffer weight and recoil spring, and expect some lowers to need gunsmith work. The manufacturer suggests starting on 124gr NATO-pressure ammunition. Blowback 9mm receivers are specifically called out as the group most likely to need fitting. Our own PSA AR-V produced ejection issues. The full tuning procedure, including the FRT-clear BCG and buffer pairing, is in our AR9 FRT build guide.

300 Blackout

Supported on properly gassed and tuned 300 Blackout AR-15s, with the same caveat that buffer weight and spring rate may need adjusting. Subsonic and suppressed 300 BLK changes the carrier speed the reset depends on, so budget range time for tuning rather than assuming a drop-in result.

AR-10 and .308

Not supported. The Triggered Company lists an AR-10 Disruptor as an announced platform, but there is no .308-rated forced reset trigger shipping from any maker right now. Dropping an AR-15 unit into an LR-308 lower carries no manufacturer support or warranty.

Tavor X95, bullpups, and other non-AR hosts

The Disruptor does not fit a Tavor X95. The X95 uses a proprietary bullpup fire control pack connected to the hammer through a linkage, not an AR-15 fire control group, so no AR-pattern drop-in cassette will go in it. The same holds for every other bullpup. The SIG MCX takes an AR-pattern trigger physically but gave us light primer strikes. For non-AR hosts, the working path is a selector-based forced reset system such as the AS Designs ARC-Fire, which keeps your existing trigger. Our FRT compatible guns guide lists what actually exists per platform.

Installation is straightforward for standard AR-15 lowers. The cassette drops in, the included anti-walk pins secure it with a torx wrench (the only tool required), and you're done. We had ours installed in under five minutes. There are a few considerations worth noting:

• →M16-cut lowers: The extra clearance in M16/auto sear pocket lowers can allow a critical internal screw to back out. Staking is recommended for these receivers.
• →Reassembly tip: When closing the upper and lower receivers, pull the charging handle back slightly to ensure the trip bar aligns correctly. A credit card or similar tool can help depress the trip bar during reassembly.
• →Buffer weight:Use H2 minimum with sliding weights. H3 is recommended for 16" and shorter barrels to ensure consistent cycling in FRT mode.

The Rare Breed FRT-15 established the forced reset trigger market, but the Partisan Disruptor offers meaningful improvements at a lower price point.

Our launch unit's semi-auto break was noticeably grittier than a milspec trigger, which is why the original version of this review told people to buy the Disruptor for FRT mode alone. The newer revision changes that verdict: with a defined wall and a clean break, semi-auto mode is now genuinely usable, and the Disruptor at $299 is doing more work for the money than the Rare Breed at $380 and up.

In May 2025, the U.S. Department of Justice settled ongoing litigation over Rare Breed FRTs. ATF's return guidance says the federal government agreed not to enforce machine-gun theories against eligible FRT possession or transfer, while excluding switches, drop-in auto sears, lightning links, trigger-control-group travel reducers, and other machinegun conversion devices.

Check your state and local laws before purchasing. Some jurisdictions have enacted their own restrictions on rate-increasing devices regardless of federal classification. For the current state-by-state breakdown including the Minnesota ruling, see our binary trigger legal states 2026 guide.
