Best FRTs Compared: Super Safety vs Disruptor vs Atrius vs Kabuto

The best FRT for you depends less on brand than on type. In 2026, forced-reset options fall into three groups: trigger replacements like the Rare Breed FRT-15L3 and Partisan Disruptor, selector-based devices like the Redacted Arms Super Safety and Atrius FRS, and drop-in reset devices like the Kabuto. Prices run from about $120 to $450, and nearly all of them need an M16-profile bolt carrier group and a heavier buffer. Before you spend money on firearm parts and accessories for a reset build, compare what each one actually requires. The cheapest FRT can become the most expensive one once you add the parts it needs.

Prices are from each maker’s site or a major dealer on November 10, 2026, and can change.

FRT vs Forced Reset Selector vs Drop-In: What’s the Difference?

All of these devices reset the trigger using the bolt carrier’s movement, and all still need one trigger function per shot. Where they do it is what separates them:

• Trigger replacements (FRT-15L3, Disruptor) swap out your whole fire control group for a cassette with its own reset mechanism.
• Selector-based devices (Super Safety, Atrius FRS, ARC-Fire) replace the safety selector and work with a trigger you choose. Searchers often call the Atrius an “FRT,” but it’s a forced reset selector, the same family as the Super Safety.
• Drop-in reset devices (Kabuto) sit in the lower and work with the factory trigger.

Our comparison of the Super Safety vs a forced reset trigger goes deeper into how the selector-based and trigger-based designs differ mechanically.

How We Compared These FRTs

We looked at the same six things for every device: price, type, which platforms it fits, what bolt carrier and buffer it needs, how hard it is to install, and the known issues reported by makers and owners. We didn’t rank by rate of fire, because no reliable independent test data exists and speed depends mostly on the shooter, the ammo and the rifle’s tuning.

Redacted Arms Super Safety

The Super Safety replaces your safety selector and works with a cut mil-spec trigger, a straight trigger, or a complete fire control group, depending on the kit. Prices start at $119.99 for the DIY version and run to $249.99 for the FCG and H3 kit, with the RAS 3-position selector at $199.99. It’s the only option here with versions for the AR-15, AK, MP5 and AR-9, and Redacted Arms also makes a separate reset part for the Taurus TX22. It carries a lifetime warranty.

The trade-off is that the standard version needs a cut trigger, and the RAS selector needs a separate lever blocker with tailless hammers such as most Geissele triggers. Best for: shooters who want one system across several platforms, or who want to keep a trigger they already like.

Partisan Disruptor

The Disruptor is a drop-in trigger cassette now sold under The Triggered Company name, at $299.99–324.99 depending on finish and ambidextrous controls. It installs without fitting and uses anti-walk pins. In February 2026, the maker issued a quality-control notice about an out-of-spec batch and offered replacements, so check the batch on any used Disruptor. Reviewers describe the take-up as gritty compared with a good standalone trigger. Best for: AR-15 owners who want a complete cassette with no fitting.

Atrius FRS

The Atrius forced reset selector keeps your existing trigger, which suits shooters who don’t want to swap the fire control group. Dealers list the standard version at about $179.99 (MSRP $199), the ambidextrous version at about $229.99 (MSRP $249), and the G-Lever version for Geissele triggers at $249. It needs an uncut mil-spec trigger, some fitting may be required, and reviewers describe it as more tuning-sensitive than a cassette-style FRT. Best for: shooters who want a selector device but don’t want to cut a trigger.

Kabuto

The Kabuto is a drop-in reset device sold by several shops rather than a single brand, which means quality and support vary by seller. Current Gen 3 listings run about $120. It works with the factory trigger, and most sellers recommend an H3 buffer. Best for: budget AR-15 builds, as long as you buy from a seller you trust.

Rare Breed FRT-15L3

The FRT-15L3 is the best-known forced reset trigger and the most expensive, at $450 direct from the maker. It’s a drop-in cassette with a three-position selector and requires a full-auto profile BCG. The maker lists a heavier pull than most, about 4.5–5 lb in semi and 6.5–7 lb in forced-reset mode. Rare Breed sells only direct, and many lookalike storefronts use its name. Best for: shooters who want the original design and don’t mind the price.

AS Designs ARC-Fire V2

The ARC-Fire V2 is a forced reset selector at $199.99, or $249.99 for the ambidextrous kit. It covers more platforms than most selector devices, including the MCX, MPX, MP5 and SCAR. Some users report light primer strikes that need buffer or spring tuning. Best for: owners of non-AR platforms like the MPX or SCAR.

Which FRT Is Easiest to Install?

Cassette-style FRTs like the Disruptor and FRT-15L3 are usually the easiest: remove the old trigger group, drop in the cassette, and pin it with anti-walk pins. Selector-based devices take a little more care, because the selector, detent and trigger have to work together, and some need a cut trigger or a lever blocker. Drop-in reset devices like the Kabuto sit between the two. Whatever you choose, plan on a function check and a buffer test before your first full range session.

What Do You Need for Any FRT?

Budget for the full setup, not just the device:

• An M16-profile BCG. Almost every option needs the extra mass and full-length carrier. Our guide to why the Super Safety requires an M16 BCG explains why.
• A heavier buffer. Most makers recommend H2 at minimum and H3 for short or suppressed rifles.
• The right lower and trigger. Check your lower’s shelf, whether your device needs a cut or uncut trigger, and whether your hammer is compatible.

Add those parts and the real cost of a $120 device can pass $300, while a kit that already includes them can cost less overall.

Which FRT Works on an AK, MP5 or AR-9?

Most FRTs are AR-15 only. If you also shoot an AK, MP5-pattern gun or AR-9, the Super Safety line is the only option in this comparison with versions for all four platforms. The ARC-Fire V2 covers the MP5 but not the AK.

If you own more than one platform, staying with one system also means one set of install steps, one support team, and spare parts you already understand. Over several builds, that usually matters more than a small price difference on a single device.

How to Avoid Fake FRT Stores

Because FRTs are in demand and often sold out, fake storefronts are common. Buy from the manufacturer or an authorized dealer, be wary of prices far below retail, and check that the domain matches the maker’s real site. Pay with a method that offers buyer protection, and avoid any seller that only accepts wire transfers, cryptocurrency or gift cards. If a deal on a $450 FRT looks too good to be true, it usually is.

Are FRTs Legal Where You Live?

Forced-reset devices for rifles are not treated as machine guns under federal law after the 2025 settlement between the Department of Justice and Rare Breed, described in the DOJ’s settlement announcement. Many states still ban them or any device that increases the rate of fire. Check your state’s law before you buy. This is not legal advice.

Choose the Best FRT for Your Build

The best FRT is the one that fits your platform, your trigger and your budget once every required part is counted. If you want one system that works across AR-15, AK, MP5 and AR-9 builds, start with the Redacted Arms Super Safety with cut trigger.
