Key Takeaways
- →Four makers ship factory FRT guns:the One Horse Express, B&T's SPC9 and GHM9, the LSD Arms billet AR-15, and the Tippmann M4-22 ELITE FRT rimfire all ship with a forced reset device installed and tuned at the factory.
- →Cheapest is the One Horse Express at $999:a 16" 5.56 AR-15 with the Atrius Forced Reset Selector fit, timed, and tested on the line ($1,199.99 MSRP, $999.99 introductory).
- →B&T goes factory:the SPC9 and GHM9 are assembled and tested with the Rare Breed FRT-SG3 on B&T USA's production line. The $525 FRT-SG3 also sells separately for SPC9, GHM9, and GHM45 owners.
- →Two premium builds: the LSD Arms billet AR-15 packages the Triggered Company Disruptor and an Odin Works heavy buffer from $1,999, and the Tippmann M4-22 ELITE Rifle FRT runs the Rare Breed FRT-15L3 in .22 LR at $1,578.
- →Factory tuning is the point: an FRT lives or dies on buffer and spring timing, and these guns arrive with that work done and test-fired, instead of leaving it to the buyer.
The Factory FRT Category
Five firearms from four makers now ship from the factory with a forced reset device installed: One Horse's Express AR-15 with the Atrius Forced Reset Selector, B&T's SPC9 and GHM9 carbines with the Rare Breed FRT-SG3, the LSD Arms billet AR-15 with the Triggered Company Disruptor, and the Tippmann M4-22 ELITE FRT in .22 LR with the Rare Breed FRT-15L3. Prices run from $999 for the One Horse Express to $1,999 and up for the LSD Arms rifle. Until now, a forced reset trigger meant sourcing the device, matching a heavier buffer, and tuning the timing yourself; these guns move that work to the assembly line.
The distinction that matters is between a forced reset trigger and a forced reset selector. The Disruptor and the Rare Breed FRT cassettes are complete drop-in fire control groups. The Atrius FRS is a three-position selector that replaces the safety and drives an existing mil-spec trigger forward into reset off the bolt's rearward travel. Both deliver the same result, one round per trigger function at a very fast semi-automatic rate, but they install differently. For the full cross-platform breakdown of which device fits which host, our FRT buyer's guide ranks the current field, and the FRT-compatible guns guide covers hosts you can build one on.
| Firearm | Forced Reset Device | Caliber | Price |
|---|---|---|---|
| One Horse Express | Atrius Forced Reset Selector | 5.56 NATO | $999.99 intro |
| B&T SPC9 / GHM9 | Rare Breed FRT-SG3 | 9mm | Host + $525 trigger |
| LSD Arms FRT Rifle | Triggered Company Disruptor | 5.56 NATO | From $1,999 |
| Tippmann M4-22 ELITE FRT | Rare Breed FRT-15L3 | .22 LR | $1,578 rifle |
One Horse Express: The $999 Factory FRS AR-15
The One Horse Express is the cheapest way into a factory forced reset gun at $999.99 introductory ($1,199.99 MSRP). Austin-based Atrius Development Group partnered with One Horse to build it, and every Express has the Atrius Forced Reset Selector fit, timed, and tested at the factory. The rifle is a 16-inch 5.56/.223 AR-15 with a nitride-treated barrel, a 1:8 twist, a mid-length gas system with a low-profile gas block, a 15-inch M-LOK handguard, and an H2 buffer. It wears a THRiL grip and stock and a Breek Warhammer Mod2 charging handle, and feeds from a 30-round magazine.
The Atrius FRS is a single-side, three-position selector marked Safe, Semi, and Super-Semi. In Super-Semi the selector interacts with the fire control group during cycling to force the trigger forward into reset after each round, and the shooter still presses the trigger again for the next shot. Because it is a selector rather than a trigger cassette, the Express keeps a standard mil-spec fire control group and layers the reset function on top of it. For a hands-on evaluation of that selector on its own, see our Atrius FRS review, and for the full launch breakdown, our One Horse Express coverage.

B&T SPC9 and GHM9: Rare Breed FRT-SG3 on the Line
B&T USA and Rare Breed are factory-integrating the FRT-SG3 forced reset trigger into the SPC9 and GHM9, assembled and tested on B&T USA's production line, per the Rare Breed and B&T USA announcement. That is a meaningful move for the B&T 9mm family, which has had almost no forced reset aftermarket; the prior path was swapping to an AR fire control group in a third-party lower. The FRT-SG3 is the first drop-in forced reset trigger for the SPC9, GHM9, and GHM45, requiring no gunsmithing, fitting, or machining.
The FRT-SG3 is a duty-grade three-position unit, Safe, Semi, and FRT, manufactured and assembled in the USA specifically for the SPC and GHM platforms. Its custom housing drops into the correct B&T lower with a three-position ambidextrous B&T-style safety selector and B&T-style hammer and trigger axle pins in the box. As a standalone drop-in for owners who already have a host, it sells for $525 direct from Rare Breed Triggers. For the full breakdown of the factory integration and the platforms it covers, see our Rare Breed FRT-SG3 coverage.

LSD Arms: Billet AR-15 With the Triggered Company Disruptor
LSD Arms ships a small-batch billet AR-15 with the Triggered Company Disruptor forced reset trigger and an Odin Works heavy buffer installed, listed from $1,999. LSD Arms lists receivers machined from 6061-T6 aluminum billet with a proprietary handguard and a bolt-on shell deflector, offered in 15-plus Cerakote colors, and sells direct through an inquiry form rather than through retail dealers.
The Disruptor is a three-position drop-in cassette, Safe, Semi, and Enhanced Semi, with 17-4 stainless and 4140 chromoly wear surfaces and a listed 3.75 to 4.1 lb pull. Pairing it with an Odin Works heavy buffer out of the box is the whole value case, since the Disruptor needs that buffer mass to reset cleanly. For the full specs, the buffer logic, and who LSD Arms is, see our LSD Arms FRT rifle coverage.

Tippmann M4-22 ELITE FRT: Forced Reset in .22 LR
The Tippmann M4-22 ELITE FRT is the only rimfire in the group, built by Tippmann Arms and Rare Breed around the Rare Breed FRT-15L3. The M4-22 ELITE Rifle FRT lists at $1,578.00 and the Pistol FRT at $1,608.95, both in .22 LR. The rifle carries a 16-inch barrel, a 12-inch M-LOK handguard, a 1/2x28 threaded A2 birdcage, and a 25-round magazine, and weighs 5 lb 8 oz. It runs an ambidextrous three-position selector, Safe, Semi, and FRT, with a 4 to 4.5 lb semi pull and a 5.5 to 6 lb forced reset pull.
A centerfire FRT-15L3 relies on the AR-15's full-auto-profile bolt carrier and an H2 or H3 buffer to time the reset, and a blowback .22 has neither. Tippmann engineered a Patent Pending anti-bounce bolt system, modified receivers, and optimized buffer components so the FRT-15L3 cycles reliably on rimfire ammo. That makes the FRT experience cheap to feed and low on recoil. For the engineering detail and the rifle-versus-pistol spec split, see our Tippmann M4-22 ELITE FRT coverage.

Why Factory-Installed Matters
A forced reset device only runs when the buffer and spring are matched to it, and that tuning is where most owner installs go wrong. The Triggered Company specifies a minimum H2 buffer, with H3 recommended, for carbine-length gas systems on 16-inch or shorter barrels; a buffer that is too light causes bolt bounce, light primer strikes, and a reset that does not complete before the next cycle. Factory guns arrive with that combination already solved: the One Horse Express ships with an H2 buffer, LSD Arms includes an Odin Works heavy buffer, and Tippmann built a Patent Pending anti-bounce bolt to control carrier timing on a fast blowback action.
Buying the tuning done puts the gun-and-trigger pairing on one maker rather than a trigger you dropped into someone else's rifle, and it removes the trial-and-error of finding the right buffer weight. Eligible forced reset triggers covered by the May 2025 DOJ settlement are not treated as machine guns under federal law; the settlement dropped the government's appeal and left standing the district court ruling that a forced reset trigger fires one round per trigger function and is not a machine gun. The constraint is state law: several states restrict or ban forced reset triggers, and makers maintain no-ship lists that are often broader than the statutory bans, so confirm your own state before ordering. To spec an FRT-ready host with your own buffer, handguard, and optic choices, build one in our rifle builder.

Bottom Line
The factory FRT gun is now a real category with four entries at four price points. The One Horse Express at $999 is the value pick, delivering a factory-timed Atrius selector on a standard 5.56 AR-15. B&T's SPC9 and GHM9 bring forced reset to the 9mm carbine, a platform that had none. LSD Arms and Tippmann sit at the premium end, one a billet AR-15 with the Disruptor and a tuned buffer, the other a low-recoil .22 LR trainer engineered around the FRT-15L3.
The reason to buy factory over a home install is the tuning: the buffer, spring, and, in Tippmann's case, a purpose-built bolt are matched to the trigger before the gun ships. Confirm your state allows forced reset devices, then start with our FRT buyer's guide to match a device to your platform.
