What Triggers Work With the Atrius Forced Reset Selector? (RISE Compatibility Guide)

Seven RISE triggers are confirmed compatible with the Atrius Forced Reset Selector (formerly the Super Selektor): five in RISE’s main retail lineup (Rave 140, Blitz, RA-434 HPT, RA-535 APT, and LE145) plus two OpticsPlanet exclusives (RA-240 and RA-242). Jump to the compatibility table for specs and pricing, or keep reading for the full breakdown of which one fits your build.

You bought an Atrius Forced Reset Selector, or you’re about to. Now you need a trigger that actually works with it. Most compatibility info is scattered across forums, comment threads, and YouTube install videos.

Below: what a super safety is, how it works, the difference between a forced reset selector and a forced reset trigger, and the five RISE triggers confirmed compatible with the Atrius Forced Reset Selector (the FRS).

A note on the law

Forced reset selectors became federally legal in May 2025 following the DOJ settlement that ended the ATF’s enforcement position against them. As of May 2026, approximately 14 states plus Washington, D.C. continue to restrict FRS devices under “multiburst trigger activator” or “rapid-fire activator” statutes, including California, New York, New Jersey, Illinois, and Washington. State laws change. This page is general information, not legal advice. Verify current federal and state law and consult a qualified attorney in your jurisdiction before purchasing or installing any firearms accessory.

What Is a Super Safety on an AR-15?

A super safety is a three-position selector that replaces the standard SAFE / SEMI selector on your AR-15. The third position adds forced-reset firing, labeled FULL-SEMI on the Atrius, which speeds up your follow-up shots without changing the trigger group itself.

You’ll see this category called several things online: super safety, forced reset selector (FRS), super selector, Super Selektor. They’re all the same idea. The Atrius Forced Reset Selector (originally marketed as the Atrius Super Selektor) is the most popular one on the market today.

What Does a Super Safety Trigger Do?

A super safety doesn’t change your trigger. It changes how your trigger resets.

On a standard semi-auto, every shot requires four things from you: pull the trigger, the hammer drops, the bolt cycles, and you release the trigger forward to let it reset. Your finger is the rate-limiting step.

A super safety extends a small cam and lever down into the lower receiver behind the trigger bar. When the selector is rotated to FULL-SEMI, the lever engages your trigger. As the bolt carrier cycles rearward and returns to battery, the lever physically pushes the trigger forward against your finger and completes the reset before the bolt closes.

You still have to function the trigger separately for every shot. The rifle just resets it for you mechanically. The result is dramatically faster follow-up shots without giving up the predictability of your existing trigger.

Super Safety vs. FRT: What’s the Difference?

This is where shoppers get tangled. Two categories, two completely different parts.

Forced Reset Trigger (FRT): A complete drop-in trigger cassette. The forced-reset behavior is engineered into the trigger itself. Examples: Rare Breed FRT-15, Wide Open Trigger, Partisan Disruptor. You install one of these and you’re done; no separate selector needed.

Forced Reset Selector (FRS), also called a super safety: A safety-selector replacement only. The reset mechanism rides off your existing single-stage trigger. Examples: Atrius Forced Reset Selector (formerly the Super Selektor), Hoffman Tactical Super Safety, AS Designs Arc-Fire. You keep your trigger group; you swap the selector.

If you already own a compatible single-stage trigger, an FRS like the Atrius is the simpler upgrade. If you don’t, you’re choosing between buying a complete FRT cassette or pairing a compatible single-stage trigger with an FRS.

What the Atrius Needs in a Compatible Trigger

The Atrius cam lever needs a specific trigger geometry to work cleanly. Per Atrius’s compatibility documentation, the rifle needs:

• A mil-spec single-stage trigger with a flat, squared-off rear on the trigger bar. No U-notch, no relief cut, no dip.
• A low-shelf or full-profile (M16) trigger pocket in the lower receiver.
• A full-profile (M16/FA) bolt carrier group. The RISE AR-15 BCG, in both black nitride and nickel boron, features a full-auto profile.
• A carbine-length buffer tube. Pistol-length tubes are not compatible.
• H2 or H3 buffer recommended for reliable primer ignition.

Two-stage triggers won’t work. The geometry of the second stage interferes with the forced-reset lever. Drop-in cassette triggers are case by case; some work cleanly out of the box and some don’t. Atrius publishes a confirmed-compatible list, and five RISE triggers are on it.

RISE Triggers Compatible With the Atrius Forced Reset Selector

Per Atrius’s official compatibility chart at atrius.dev/compatibility, seven RISE drop-in single-stage triggers are confirmed compatible with the Atrius Forced Reset Selector. The five triggers in RISE’s main retail lineup are shown below; two additional models (the RA-240 and RA-242) are confirmed compatible and sold exclusively through OpticsPlanet.

RISE Trigger	Pull Weight	Best For	Key Feature	MSRP
Rave 140 Trigger	3.5 lbs.	First-time builders; budget upgrades	NoWay Take-Up™	$149.99
LE145 Tactical Trigger	4.5 lbs.	Duty / home defense	Duty-grade safety margin	$149.99
RA-434 High-Performance Trigger (HPT)	3.5 lbs.	Versatile do-everything builds	Nickel boron internals	$189.99
Blitz Trigger	3.0–3.5 lbs.	Speed shooters, 3-Gun	Quik-Klik™ Reset	$209.99
RA-535 Advanced-Performance Trigger (APT)	3.5 lbs.	Cleanest break, precision; Competition	Nickel-Teflon® internals	$259.99

All five are single-stage drop-in cassettes machined from 6061 aluminum housings with heat-treated S7 tool steel internals. The flat, squared trigger-bar geometry the Atrius needs is built into all five out of the box. No modification required.

Note on the Rev 535: The Rev 535 has not been confirmed compatible with the Atrius yet. If you want a confirmed pairing today, choose the RA-535 APT.

Also confirmed compatible: The RA-240 and RA-242 pair with the Atrius the same way the five triggers in the table do. Both are OpticsPlanet exclusives, sold only through OpticsPlanet’s storefront.

Which RISE Trigger Is Right for Your Atrius Build?

You’re building your first AR and the Atrius is your first major upgrade. Go with the Rave 140 Trigger. It’s the most accessible price point on the list. NoWay Take-Up™ gives you zero slack before the sear releases, so the Atrius’s forced reset starts from the same clean position every cycle. You get the real upgrade feel without overspending on your first build. It’s the entry point in the RISE lineup, though, so if you eventually start chasing competitive split times, the Blitz or RA-535 APT is the next step up. Available in curved or flat blade.

You’re building a duty rifle or a home-defense rifle. The LE145 Tactical Trigger is RISE’s 4.5 lb. duty-grade single-stage. The heavier pull is intentional for safety-critical contexts. Worth knowing before you install: the Atrius’s forced reset will feel different on a 4.5 lb. trigger than it does on a 3.5 lb. trigger, so plan some range time to dial it in before you trust it in a defensive context.

You want premium internals at a mid-range price. The RA-434 High-Performance Trigger combines smoothness and speed without stepping into top-tier money. Friction-reducing nickel boron coating on the interior parts delivers a smooth pull and a crisp, glass-like break, which means the Atrius’s forced reset starts from the same clean position every time. The break isn’t quite as refined as the RA-535 APT’s, but the $70 price difference makes the RA-434 HPT the smart-money pick on the list. The Patriot Trigger is a close sibling in this tier: same 3.5 lb premium drop-in build and ultra-short reset, in a unique anodized design honoring Folds of Honor that gives back to veterans and their families.

You’re running fast drills, pin-shooting, or 3-Gun-style strings. The Blitz Trigger is built around speed. Its LiteMite™ Hammer cuts hammer mass without giving up strike energy, and the Quik-Klik™ Reset is short, audible, and tactile. The faster a trigger resets on its own, the more you get out of the Atrius’s mechanical reset stacked on top. This is the pairing for shooters chasing split times. If you’re not actively running timed drills, the RA-434 HPT delivers similar smoothness for less money.

You want the cleanest break on the compatibility list. The RA-535 Advanced-Performance Trigger is RISE’s signature performance trigger. Nickel-Teflon® internals cut friction across every contact point, the reset is ultra-short, and overtravel is nearly nonexistent. Paired with the Atrius, every shot feels deliberate and identical to the last one. The price reflects the build, so if you’re putting it in a casual range rifle, you may be paying for refinement you won’t fully use.

What RISE Triggers Are Not Compatible With the Atrius Forced Reset Selector

A few RISE triggers will not pair with the Atrius. If FRS compatibility is part of your build plan, skip these:

• Rev 535: Not yet confirmed compatible with the Atrius. The Rev 535 is the next-generation evolution of the RA-535 APT, so choose the RA-535 APT if you want a confirmed forced-reset pairing today.
• ICONIC Independent Two-Stage Trigger: Two-stage triggers are incompatible with FRS devices as a category, because the geometry of the second stage interferes with the forced-reset cam lever. This applies to the ICONIC and to any other two-stage trigger.
• Reliant Hunter: A Remington 700 bolt-action trigger, not an AR-15 trigger. The Atrius is built for the AR-15 platform; the Reliant Hunter is built for an entirely different rifle.
• RA-100 and RA-101 component triggers: These are component-style triggers (not drop-in cassettes), and Atrius compatibility for component triggers depends on case-by-case trigger-bar geometry. Neither is currently on Atrius’s confirmed-compatible list.

Why RISE Triggers Pair Best With the Atrius

The Atrius’s job is to reset your trigger before your finger can. The faster your trigger already resets on its own, the more total speed the system gives you. That’s the engineering case for pairing the Atrius with a RISE trigger.

All five confirmed-compatible RISE models are built around three things the Atrius rewards:

• Squared trigger-bar geometry out of the box. No cuts, no shimming, no modifications. The Atrius cam lever engages cleanly on every cycle because the geometry is already right. Most aftermarket triggers in this category require some kind of trigger-bar work to play nicely with an FRS. RISE doesn’t.
• Short, tactile resets engineered in. Quik-Klik™ Reset on the Blitz, ultra-short reset on the RA-535 APT, fast reset on the RA-434. Every RISE single-stage on the compatibility list has reset travel cut down at the design stage. That compounds the Atrius’s mechanical reset on top.
• Consistent pull weights, shot to shot. Heat-treated S7 tool steel internals and AS9100 aerospace-tolerance machining mean pull weight doesn’t drift over thousands of rounds. The Atrius can’t fix a trigger that gets gritty after a few range trips. It can only speed up what’s already there.

That’s why all five RISE triggers above sit on the Atrius confirmed-compatible list, and why RISE is the simpler, faster pairing for any AR-15 you’re building around an FRS.

Frequently Asked Questions

Q: Is the Atrius Forced Reset Selector legal?

A: Forced reset selectors like the Atrius Forced Reset Selector became federally legal in May 2025 following the DOJ settlement that ended the ATF’s enforcement position against them. As of May 2026, approximately 14 states plus Washington, D.C. restrict FRS devices under “multiburst trigger activator” or “rapid-fire activator” statutes, including California, New York, New Jersey, Illinois, and Washington. Atrius publishes a compatibility and shipping chart at atrius.dev/compatibility that lists which states they will ship to. State laws change, so verify your state law before ordering and consult a qualified attorney in your jurisdiction if you are unsure.

Q: Can I use the Rev 535 with the Atrius?

The Rev 535 has not been confirmed compatible with the Atrius Forced Reset Selector. The Rev 535 is the next-generation evolution of the RA-535 APT and uses a different installation system, so it is not currently on Atrius’s confirmed-compatible list as of May 2026. If you want a confirmed forced-reset pairing today, choose the RA-535 Advanced-Performance Trigger (APT) instead.

Q: Will a two-stage trigger work with a forced reset selector?

No. Forced reset selectors require a single-stage trigger to function correctly. The geometry of a two-stage trigger’s second stage interferes with the cam lever that forces the trigger reset, so two-stage triggers do not pair with FRS devices as a category. This applies to the ICONIC Independent Two-Stage Trigger and to any other two-stage trigger from any manufacturer.

Q: What’s the most affordable RISE trigger compatible with the Atrius?

The Rave 140 Trigger is the most affordable RISE trigger confirmed compatible with the Atrius Forced Reset Selector, at an MSRP of $149.99. It’s a single-stage drop-in cassette with NoWay Take-Up, meaning zero slack before the sear releases, so the Atrius’s forced reset starts from the same clean position every cycle. It’s a strong first pairing for shooters new to FRS devices.

Q: Do I need a special buffer for the Atrius FRS?

The Atrius Forced Reset Selector requires a carbine-length buffer tube and a full-profile (M16/FA) bolt carrier group. An H2 or H3 buffer is recommended for reliable primer ignition during forced-reset firing. A pistol-length buffer tube is not compatible with the Atrius.

Q: Does the Atrius work on a pistol-length AR?

No. The Atrius Forced Reset Selector requires a carbine-length buffer tube to function correctly. Pistol-length buffer tubes are not compatible because the cam lever geometry depends on a specific buffer tube length and configuration.

Q: How many RISE triggers are compatible with the Atrius in total?

Seven RISE triggers are confirmed compatible with the Atrius Forced Reset Selector. The five in RISE’s main retail lineup are the Rave 140, Blitz, RA-434 HPT, RA-535 APT, and LE145. Two additional models, the RA-240 and RA-242, are confirmed compatible and sold exclusively through OpticsPlanet.
