Partisan Disruptor FRT Review: The Best Forced Reset Trigger for 2026
The Partisan Disruptor brings forced reset technology to the AR-15 platform at $299 with a cassette drop-in design and 3-position selector. We bought one with our own money to test. The FRT mode works as advertised, but the semi-auto trigger and safety selector have some rough edges.
Key Takeaways
- →3-Position Selector: Safe, Semi-Auto, and Enhanced Semi-Auto (forced reset) modes in a single trigger unit
- →True Drop-In Design: Cassette-style installation requires no gunsmithing, fitting, or lower modification
- →$299 Price Point: Undercuts competitors significantly, though the semi-auto trigger feel is a trade-off
- →Legal Status: Eligible FRTs are covered by the May 2025 DOJ settlement at the federal level, but state restrictions still apply
- →Buffer Requirements:Minimum H2 buffer (H3 recommended) for reliable cycling on 16" and shorter barrels. The Odin Works H-FRT ships pre-tuned for FRT cycling at $79.

What is a Forced Reset Trigger?
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.

Design and Construction
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. Partisan 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
The semi-auto trigger reset is indeed clean and short. However, the break itself is noticeably gritty, worse than a standard milspec trigger. This is a brand new unit, so it may smooth out with break-in, but out of the box the semi-auto mode is not something you would choose over a basic milspec FCG for precision work.
The safety selector is also worth noting: it is significantly larger than a standard AR-15 selector, less positive in its detent than milspec, and non-ambidextrous. It works fine and the 3-position function (Safe/Semi/Enhanced) operates as intended, but the feel is a step down from what most shooters are used to.
Update: Ambi Selector Variant Now Available ($299.99)
Triggered Company (the rebranded Partisan Triggers) now sells a Disruptor variant with the SBW ambidextrous selector pre-installed for a $25 premium over the standard SKU. Internals are identical to the trigger reviewed here; the only change is the both-side selector lever. For left-handed shooters or anyone who switches shoulders behind barricades, this is the SKU to buy instead. Right-handed shooters with no ambi need should stick with the standard Disruptor reviewed above.

Ambidextrous-safety version of the Disruptor FRT for left-handed and switch-shoulder shooters
- +Ambidextrous safety fixes the single biggest ergonomic complaint about the standard Disruptor
- +Works for left-handed shooters and switch-shoulder barricade work
- +Same fast forced-reset mechanism as the proven non-ambi cassette
- −$25 premium over the non-ambi version for selector-only change
- −Semi-auto break is still gritty compared to milspec, internals are unchanged
- −Requires H2/H3 buffer for carbine-length guns (additional cost)
Performance Testing
Partisan 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.

Installation Notes
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.
Partisan vs. Rare Breed FRT
The Rare Breed FRT-15 established the forced reset trigger market, but the Partisan Disruptor offers meaningful improvements at a lower price point.
| Feature | Partisan Disruptor | Rare Breed FRT-15 |
|---|---|---|
| MSRP | $299 | $380+ |
| Semi-Auto Pull | Gritty break, clean reset | Good |
| Safety Selector | Oversized, non-ambi | Standard |
| Selector Positions | 3 (Safe/Semi/FRT) | 3 |
| Design Origin | TacCon 3MR lineage | Original design |
| Installation | Cassette drop-in | Drop-in |
Multiple reviewers have praised the Disruptor's semi-auto mode, though our hands-on testing found the break noticeably grittier than a milspec trigger. The reset is clean, but the overall semi-auto experience is not a selling point. Buy this for the FRT mode, not as an everyday trigger upgrade.
Legal Status (2026)
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.
State Restrictions: ATF will not return FRTs into jurisdictions where possession is illegal, and some states separately restrict forced reset triggers, trigger activators, or rate-increasing devices. Current restriction states include California, Colorado, Connecticut, Delaware, Florida, Hawaii, Illinois, Maryland, Massachusetts, Nevada, New Jersey, New York, Oregon, Rhode Island, and Washington D.C. Minnesota had a ban, but the Court of Appeals struck it down on May 26, 2026.
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.
Future Platform Support
Partisan has announced plans to expand the Disruptor line to additional platforms:
- →AK platform
- →AR-10 / .308
- →FAL
Partisan also previewed a next-gen trigger called the LAT, described as a natural evolution of the Tac-Con 3MR and a match-grade version of the Disruptor. According to Partisan, the LAT is expected to offer a finer assisted-reset trigger pull in both semi-automatic and enhanced semi modes, with a more positive reset feel, an out-of-battery safety sear, and a more accessible launch price.
Release timelines have not been announced. The AR-15 version launched in December 2025 with ongoing production meeting demand.
Partisan says the LAT launch is coming soon and is encouraging customers to join its mailing list for the official launch date and launch coupon details.

The Verdict
The Partisan Disruptor is a solid FRT at a competitive price. At $299, it significantly undercuts the Rare Breed and the cassette installation is genuinely easy: a torx wrench and five minutes is all it takes. The FRT mode works as advertised.
The trade-offs are real, though. The semi-auto trigger break is gritty, noticeably worse than a standard milspec FCG. The safety selector is oversized, less positive than milspec, and non-ambidextrous. These are not dealbreakers for a trigger you are buying specifically for forced reset functionality, but they are worth knowing about. Buffer tuning may also be required depending on your setup.
Buy it if: You want forced reset functionality on a standard AR-15 platform at a reasonable price, and you can live with a below-average semi-auto mode. Lives in a state where FRTs are legal.
Skip it if: You want a trigger that doubles as a quality semi-auto upgrade, or you run a non-AR platform. MCX, MP5, and SCAR owners should look at the AS Designs ARC-Fire instead, which works with your existing trigger across 10+ platforms.
Bottom line:The Disruptor delivers on its core promise: reliable forced reset at a fair price with easy installation. The semi-auto mode and safety selector are rough around the edges but functional. For AR-15 owners in free states who want FRT capability, it's the best value in the category. If you want to spend as little as possible and accept legal uncertainty, Hoffman Tactical's $43 Trigger Kicker is the cheapest active-reset path on the market, a single disconnector swap built to route around the Rare Breed patent injunction.
