Triggered Company LAT Launches: Match-Grade Forced Reset Trigger

The LAT is a service-rifle-match-grade, 3-position AR-15 assisted reset trigger launched July 4, 2026 at $349.99 for the single-side version and $375 for the ambidextrous version. It sits at the top of The Triggered Company's lineup, above the value-oriented Disruptor, and it is the answer for shooters who want forced-reset capability without giving up a usable semi-automatic trigger.

The Triggered Company is the rebranded Partisan Triggers, which changed names on May 1, 2026. The Disruptor is the company's simplification of the original TacCon 3MR: it combined the reset lever and main trigger piece into one part and added an out-of-battery safety, which made it cheaper to build but left the semi-auto break noticeably gritty. The LAT spares no expense and keeps the reset lever as a separate part, essentially an improved and refined 3MR, while retaining the same out-of-battery safety that traces its lineage to Browning's 1900 patent. The name honors Larry Alan Thorne, a Special Forces soldier killed in action in Vietnam in 1965.

For a full breakdown of where the LAT lands against every other forced reset system, see our FRT buyer's guide for 2026, and for the hands-on story behind the trigger it replaces, read our Partisan Disruptor FRT review. For how the LAT actually feels in hand, our LAT first-look review covers the semi-auto break in detail.

The single biggest difference is how the selector controls the reset system. On the Disruptor, the forced-reset mechanism is always in the fire-control path, which is what produces its gritty semi-auto break. On the LAT, moving the selector to standard semi completely disables the assisted reset and the out-of-battery safety, leaving a clean, single-stage 3-3.5 lb break with no forced-reset drag. Flip to the third position and the forced reset comes alive.

The rest of the upgrades follow from that match-grade intent. The LAT uses 17-4 stainless steel on its wear surfaces where the Disruptor uses tool steel. Both triggers ship as drop-in cassettes with anti-walk pins included, both use mil-spec pins, and both were validated past 6,000 rounds under a course of fire derived from the USMC M27 IAR evaluation criteria. The LAT is the refinement; the Disruptor is the value pick.

The LAT's third selector position is called ARSE, for Assisted Reset Semi Enhanced. In this position the bolt carrier's rearward movement pushes on the reset lever and mechanically forces the trigger forward against your finger, so the trigger resets at the speed of the action rather than waiting for you to release it. The firearm stays semi-automatic: one trigger function fires one round, and letting off the trigger stops the string immediately.

The payoff over a standard trigger is speed: because the action drives the trigger back to your finger, follow-up shots come faster and more consistently than manually releasing and re-pressing between rounds, all while the rifle stays semi-automatic at one round per trigger function. For the mechanical background on how forced reset compares to super safeties and binary triggers, our super safety and FRT guide breaks down each system and includes a rate-of-fire calculator, and our FRT compatible guns guide maps which platforms have a forced reset path at all.

The two LAT versions share identical cassette internals: the same 3-3.5 lb pull, 17-4 stainless construction, and ARSE function. The only difference is the selector. The single-side LAT ($349.99) exposes Safe, Semi, and Enhanced Semi on the left side of the lower like a standard AR selector. The Ambi ($375) adds a matching lever on the right side.

Buy the Ambi if you shoot left-handed or run your rifle behind barricades where you switch shoulders, since a right-side selector lets your firing-hand thumb reach the safety in either position. Right-handed shooters with no ambi requirement should save the $25 and take the single-side LAT. Both drop into the same lowers and both need the same buffer setup.

The LAT is a true drop-in cassette. It uses mil-spec pin sizes, seats in most standard AR-15 lowers with no gunsmithing, and ships with anti-walk pins; The Triggered Company notes CLAP pins are preferred. Installation is the same five-minute job as the Disruptor. Based on our Disruptor testing, M16-cut and full-auto sear pocket lowers have extra clearance that can let an internal screw back out, so staking is recommended on those receivers.

Buffer weight is the detail that makes or breaks forced-reset reliability. The LAT calls for an H2 buffer at minimum, with an H3 recommended for 16-inch and shorter barrels, and a standard rifle buffer for 20-inch A2 rifle-length systems. A too-light carbine buffer is the most common reason a forced reset trigger short strokes or fails to reset. The Odin Works H-FRT buffer ($79) ships pre-tuned with a matched flat-wire spring specifically for FRT cycling, which removes the trial-and-error step. If you are spec'ing a rifle around this trigger, our best AR-15 triggers guide covers where forced reset fits against conventional match triggers, and our interactive builder lets you configure a compatible lower, buffer, and BCG in one place.

The LAT is an AR-15 forced reset trigger, the exact category covered by the May 2025 DOJ settlement that ended the federal machine-gun classification of eligible FRTs. It fires one round per trigger function, so federally it is a semi-automatic trigger, not an NFA machine gun, and it requires no tax stamp or registration.

For the current state-by-state breakdown and how forced reset triggers differ from binary triggers under the law, see our binary and forced reset trigger legal states guide.

The LAT is the trigger for shooters who liked the Disruptor's forced reset but wanted a real semi-automatic trigger the rest of the time. By letting the selector switch the reset system off entirely in the semi position, the LAT delivers a clean 3-3.5 lb single-stage break that the always-on Disruptor cannot, and the 17-4 stainless internals back up the match-grade positioning. At $349.99 single-side and $375 for the ambi, it runs about $50 over the Disruptor, which is a fair premium for the refinement.

If your priority is the lowest price of entry into forced reset and you only care about the enhanced mode, the Disruptor still does the job. If you want one trigger that shoots like a match trigger in semi and a forced reset trigger when you flip the selector, the LAT is the better buy. Either way, budget for the correct buffer and confirm FRTs are legal where you live. Browse compatible lowers and buffers in our platform catalog or spec the whole rifle in the interactive builder.
