Best FRT for AR15 2026: 3-Position & Drop-In Forced Reset Triggers

Every pick on this page is for the AR-15.

The Triggered Company launched the LAT on July 4, 2026 as a match-grade alternative to the Disruptor. It is a 3-position forced reset trigger built around two specific upgrades the Disruptor critics have asked for: a lighter, softer semi-mode pull, a 3-3.5 lb single-stage break with no wall where the Disruptor breaks heavier against a defined one, and a new ARSE mode (Assisted Reset Semi-Enhanced) that gives the shooter variable rate-of-fire control instead of a single fixed cyclic.

Pricing & Availability: $324.99 for the single-side version or $375 with the ambidextrous selector. The LAT uses 17-4 stainless steel and a flat trigger bow, and it is validated past 6,000 rounds under USMC M27 IAR evaluation criteria.

Best For: Disruptor owners who want a cleaner semi-auto break, competitive shooters who want variable cyclic control via ARSE mode, and anyone who prioritizes trigger feel over saving $49.99. The Disruptor remains the better entry point at $275; the LAT is the upgrade for shooters who use the trigger in semi mode more often than forced reset.

Why It Matters: The Rare Breed FRT-15L3 is the original forced reset trigger and the design the rest of the category followed. Rare Breed Triggers built the FRT-15, the trigger at the center of the federal fight that ended in the May 2025 DOJ settlement, the outcome that keeps eligible FRTs from being treated federally as machine guns. Every product in this guide sells in its current legal posture because of that case. The FRT-15L3 is the current production version of that trigger.

Why Consider It: At $450 the FRT-15L3 ships as a complete drop-in cassette with an ambidextrous 3-position safety (Safe, Semi, FRT) and a full hardware kit in the box: the trigger, two anti-walk pins, four pin screws, a selector drum, two selector levers (one long, one short), two T10 torx selector lever screws, and two T10 torx wrenches. Construction is 7075 anodized aluminum and heat-treated 4140 steel. Price the ambi selector honestly, though: the Triggered Company Disruptor Ambi ships with the SBW ambidextrous selector pre-installed at $299.99, so the FRT-15L3's included ambi selector is not a price advantage. What the roughly $150 premium buys is the original design from the maker that won the DOJ settlement.

Watch Out For: The honest trade-off is pull weight. The FRT-15L3 runs 4 to 4.5 lbs in semi mode and 5.5 to 6 lbs in forced reset mode, noticeably heavier in FRT mode than the Disruptor's 3.75 to 4.1 lb pull. It requires a full-auto-compatible bolt carrier group and an H2 or H3 buffer, or alternatively an A5 buffer system. It fits mil-spec AR-15 lowers but may not fit certain Colt models or other lowers with a sear block or shelf. It is also the most expensive option in this guide.

Best For: Buyers whose reason for purchase is the original FRT from the original maker, and who accept both the roughly $150 premium over the $299.99 Disruptor Ambi and the heavier 5.5 to 6 lb forced reset pull that come with it. If your actual requirement is an ambidextrous selector, the $299.99 Disruptor Ambi is the better buy; for a first-time buyer focused on value, the $275 Disruptor remains our pick.

The AS Designs Arc-Fire V2 went on sale April 10, 2026 and started shipping April 15, replacing the original Arc-Fire as the cutting edge of forced reset selector technology. The V2 is a complete redesign rather than an iteration: AS Designs rebuilt the internal geometry with larger ARC cam surfaces, a smoother detent track, and reduced system drag, resulting in a more tactile reset and cleaner cycling during sustained rapid fire. V2 components are not backward compatible with V1 units. Read our Arc V2 SHOT Show 2026 announcement for the full feature breakdown and 5,000+ round pre-release test results.

Why It Wins: The Arc-Fire V2 ships in four SKUs: three ambidextrous kits with 0/45/90, 0/45/180, or 0/90/180 throw configurations at $249.99, plus a cheaper non-ambi 0/90/180 kit. Mil-spec selector levers (both primary and ambi sides) are now included by default instead of being an add-on like on V1. ARC components use M2 tool steel with DLC coating; selectors are 4140 steel with black oxide. Platform support spans 10+ systems including AR-15, AR-10/.308 lowers, CMMG Banshee, SIG MCX/MPX/Dissent, Grand Power Stribog, MP5, G3/HK91, HK rifles, JAKL, and Kuna through platform-specific parts. The HK MR556 and HK416 use dedicated selector and trigger geometry; our MR556 and HK416 forced-reset guide separates the HK-specific ARC-Fire route from the factory-carrier FRT-MR3. For SIG hosts, our SIG MCX forced reset trigger install guide maps the MCX, MPX, and Spear slip trip kits by caliber. Trigger compatibility covers mil-spec, Geissele SSA/SSA-E/SSA-X/SD3G, ALG, BCM PNT, PSA EPT, Aero, CMMG, and Anderson.

Watch Out For: Incompatible with LaRue MBT-2S, CMC Single Stage, and Rise Armament RA-140 triggers. The V2 is notably less finicky than V1 and the Atrius FRS, and users running pre-release units consistently report it cycles cleaner right out of the box. Day-one stock is limited and AS Designs blocks shipping into restricted jurisdictions.

What Replaces It: AS Designs has an ARC-Fire Stealth in production, a variant that swaps the V2's selector screws for roll pins, with a middle-of-October 2026 estimated drop per its September 7 status page. Pricing is not published. If you want a forced reset selector now, buy the V2; the Stealth is a hardware refinement on the same mechanism, not a reason to wait.

Best For: Multi-platform shooters, those with premium triggers they want to keep, anyone running MCX, MPX, SCAR, MP5, HK MR556/762, or B&T platforms. Read our full Arc-Fire V2 review for the hands-on verdict, and the original ARC-Fire V1 review for 400-round test results on the SIG MCX Spear LT. B&T SPC9 and GHM9 owners now also have a dedicated full FRT option: the Rare Breed FRT-SG3, which B&T USA is factory-installing under a July 2026 partnership.

The Atrius FRS was one of the first forced reset selectors to market and remains a solid option. At $209.99 it sits between the budget Mars Super Safety ($139.99) and the multi-platform Arc-Fire V2, and its mechanically leveraged design reduces stress on your rifle compared to full FRT triggers. Read our full Atrius FRS review for detailed analysis.

Why Consider It: Ambidextrous design with crisp 90-degree engagement. Heat-treated 4140 steel construction. Drop-in installation with standard mil-spec fire control groups. Three modes: Safety, Semi, and Full-Semi with instant trigger reset.

Watch Out For: AR-15 only (no multi-platform support like Arc-Fire). Single throw option (90-degree). Works with mil-spec and Geissele super safe cut triggers only, no broader aftermarket trigger compatibility. Trigger tail requires minor material removal for cam engagement. The Atrius is also known to be finicky to get running properly; expect more tinkering and tuning compared to the Arc-Fire before it runs reliably.

Best For: AR-15 shooters on a budget who want to preserve their existing trigger, those prioritizing reduced rifle wear.

Now in a factory rifle: The One Horse Express is the first production AR-15 to ship with the Atrius FRS installed, fit and timed at the factory with the H2 buffer and low-cut shelf the selector needs, for $999. It is the no-tinkering path to a forced reset rifle if you do not want to tune your own.

New for May 2026, G-Lever: Atrius released the G-Lever ($229.99), an ambidextrous variant that drops into a stock Geissele SSA, SSA-E, or G2S trigger without the super safety cut. If you already run a Geissele two-stage and do not want to file the trigger tail, the G-Lever is the Atrius to buy.

The cheapest way into forced reset is now the AS Designs M2 Super Safety Kit at $99.99. It is the standard open-source Super Safety pattern (AS Designs credits the Hoffman Tactical design by name) executed in heat-treated M2 tool steel with a DLC coating on the cam and lever, and the kit ships with a pre-cut trigger, rounded safety detent, and centering block, so the usual trigger-tail cut is already done. It comes from the same shop as the Arc-Fire V2, and AS Designs recommends having a qualified gunsmith do the install. The maker does not ship it to 15 restricted states, so check your state first.

The Mars Super Safety is the other budget selector at $139.99. Like the Arc-Fire and Atrius, the Mars replaces your safety selector and works with your existing mil-spec trigger. The 3-position selector (Safe, Semi, Enhanced Semi) uses the bolt carrier's movement to mechanically reset the trigger for faster follow-up shots.

Why Consider the Mars: The 4140 alloy steel construction is solid and installation is straightforward since you keep your existing trigger. But at $139.99 against the M2's $99.99 for the same selector-based approach, the M2 is the value pick.

Watch Out For: AR-15 only with no multi-platform support. Requires mil-spec fire control group. Not ambidextrous. Less community documentation and aftermarket support compared to Arc-Fire or Atrius. Running an AK instead of an AR? MaRs makes a separate AK forced reset trigger line that fits AKM, milled, stamped, and Draco-pattern rifles; see our best AK forced reset triggers guide for the AK-specific picks and fitment. For the HK MP5, SP5, and clone family, our MP5 forced reset triggers guide covers the drop-in cassettes, complete lowers, and trip kits that fit the roller-delayed platform. On the pistol side, our best Glock FRT triggers guide ranks the forced reset and reset-assist triggers that fit Glock fire-control groups, with the exact generation each one fits. It also covers the one selectable forced reset trigger on the pistol side, a kit whose selector switches the same Glock between a normal trigger and forced-reset mode, and which is the only Glock option that skips the Gen 4 slide-release swap the other kits need on a Gen 5.

Best For: Budget AR-15 shooters running a standard mil-spec trigger.

The Hoffman Tactical Trigger Kicker is the cheapest functional entry into forced reset behavior by a wide margin at $43, and it works differently from everything else in this guide. Instead of a self-contained cassette or a selector swap, it is an active-reset disconnector replacement. You drive out the trigger/disconnector pin, pull the standard disconnector, drop the Kicker into your otherwise mil-spec fire control group, and reinstall the pin. After a shot the hammer contacts the Kicker, which pushes the trigger back into reset and tucks under the standard safety selector to lock it until the bolt carrier returns to battery. No new hammer, trigger, springs, or modified selector is required. Our full Trigger Kicker breakdown covers the mechanism in detail.

Requirements: The Kicker depends on standard mil-spec bolt carrier and FCG geometry rather than being a self-contained unit, so the host has to be a conventional AR-15 build. Hoffman recommends a full-profile bolt carrier with a properly tuned buffer and spring. The part is hardened 4130 alloy steel.

Where It Ships: Hoffman does not ship the Kicker to California, Connecticut, Washington D.C., Delaware, Hawaii, Illinois, Massachusetts, Maryland, New Jersey, New York, Oregon, Rhode Island, or Washington; confirm the seller's current restricted-state list before ordering.

For standard trigger comparisons, see our AR Trigger Guide.

Still weighing the five systems? This is every spec that separates them, side by side: assembly type, price, selector layout, throw options, platform reach, and buffer requirements.

All forced reset systems share the same goal: mechanically reset the trigger against the shooter's finger as the bolt carrier group cycles. The firearm remains semi-automatic with one trigger function per round. The difference is that the trigger resets at the speed of the BCG rather than waiting for manual release, allowing cyclic rates of 1,000-1,200 RPM.

There are two approaches to achieving this:

• FRT (Forced Reset Trigger): Replaces your entire fire control group with a self-contained trigger unit. The Triggered Company Disruptor and the new LAT trigger are full trigger assemblies. More consistent operation, but accelerates internal wear since the entire trigger mechanism cycles at high speed.
• FRS (Forced Reset Selector / Super Safety): Replaces only your safety selector and works with your existing mil-spec trigger. The AS Designs Arc-Fire V2, Atrius FRS, and Mars Super Safety take this approach. Preserves trigger longevity, costs less, and installs faster since you keep your existing FCG.

Neither type is a binary trigger (which fires on pull and release) or a bump stock (which requires forward pressure). Forced reset systems are a distinct category of semi-automatic mechanism. If your state restricts FRTs but arguably leaves pull-and-release firing alone, compare your options in the best binary triggers guide.

Eligible FRTs covered by the May 2025 DOJ settlement are not being treated federally as machine guns. DOJ described the settlement as resolving litigation over Rare Breed FRTs, and ATF's return guidance says the federal government agreed not to enforce machine-gun theories against eligible FRT possession or transfer. That guidance also says the settlement does not cover switches, drop-in auto sears, lightning links, trigger-control-group travel reducers, or other machinegun conversion devices.

That federal posture, reinforced by the 2024 NAGR v. Garland decision in the Northern District of Texas, rests on rifle-style long guns where the magazine feeds forward of the trigger-hand grip: the AR-15, AK, MP5, and PS90 are squarely inside it. Grip-fed handguns are a different question. A forced reset trigger in a Glock, Canik, or Taurus TX22 puts the mechanism on a gun whose magazine loads into the grip the trigger hand holds. Under the settlement, Rare Breed agreed not to develop or design forced reset triggers for any pistol, a strong signal that handgun units sit outside the settled-legal zone: other makers ship grip-fed units now, but neither the settlement nor the case law resolved their status the way they did for rifle-style hosts. The DA/SA Beretta 92 is grip-fed on the same terms, and its single fitted device, install cuts, and host exclusions are covered in our Beretta 92 FRT guide. Treat pistol forced reset triggers as legally unsettled rather than settled-legal, and confirm current federal, state, and local law before buying one.
