Mounted Guillotine

Last updated: June 18, 2026

What is a mounted guillotine?

The guillotine itself is a front choke. One arm wraps around the front of the opponent’s neck, the forearm bone presses up under the throat or jaw, and the squeeze cuts off blood or air until the opponent taps or goes unconscious. The name comes from the French execution device, since the trapped head and the encircling arm loosely resemble a neck held under a blade.

What sets a mounted guillotine apart is the position rather than the grip. “Mount” is the spot where one fighter straddles another who is lying on their back, knees pinning the hips. Catching the guillotine from there flips the usual problem with the move. A standard guillotine is most often finished from closed guard, on the bottom, which is exactly why some fighters avoid it. Commenting on a guillotine attempt at UFC 264, Israel Adesanya pointed out that the choke’s biggest drawback is that it tends to leave the attacker underneath. The mounted version answers that complaint directly: the choke and the better position arrive together.

Fighters usually reach it one of two ways. Sometimes an opponent caught in a guillotine tries to roll out of it, and the attacker follows the roll up into mount. Other times, a sweep or a scramble lands the attacker on top, and the neck is simply there to take.

How the mounted guillotine works

Picture someone seated high on their opponent’s torso, one arm cinched around the neck, the other hand gripping the first to lock the circle. From low mount, the bodyweight does much of the work. The attacker pulls the head up toward the opponent’s hips and settles their weight down, so the neck has nowhere to go.

The choke can run two ways. As a blood choke, the forearm bone compresses the carotid arteries on the sides of the neck and starves the brain of blood, which brings on unconsciousness fast. As an air choke, it crushes the windpipe instead, which is slower and harder on the throat. Most coaches train the blood-choke version. A 2021 study summarized by Jits Magazine put the standard guillotine at about 8.9 seconds to unconsciousness and the arm-in version at roughly 10.2 seconds.

From mount, the no-arm version (just the neck, with no trapped arm) tends to show up more than the arm-in. Top pressure already removes most of the opponent’s options, so the attacker rarely needs the trapped arm to hold them in place.

Mounted guillotine vs the standard guillotine

Most people searching this term have run into both names and want to know whether they describe different moves. The grip and the choking mechanics are the same. What changes is where the attacker’s body sits, and that single change rewrites the risk.

	Standard (closed guard) guillotine	Mounted guillotine
Attacker’s position	Underneath, on the back	On top, in mount
If the choke fails	Opponent may pass to a top position	Attacker keeps mount
Finishing force	Hips extend, legs push	Bodyweight presses down
Common in MMA	Yes, often off a takedown	Less common, positionally safer
Trapped arm	Frequently arm-in	Usually no-arm

The takeaway is positional. A bottom guillotine is a gamble: land it, and you win, miss it, and you may have handed away top control. A mounted guillotine carries far less of that downside, which is why it reads as the safer choice when a fighter already holds the dominant spot.

Common variations

Two grip choices come up most. The no-arm guillotine catches only the neck and presses the forearm straight into the throat. The arm-in guillotine traps one of the opponent’s arms inside the choke alongside the neck, which blocks many escapes but spreads the pressure out and tends to take a little longer.

There is also the high-elbow guillotine, sometimes called the Marcelotine after Marcelo Garcia, who built a famous submission game around it. Lifting the choking elbow above the opponent’s shoulder line sharpens the angle into the neck and tightens the squeeze.

Frequently Asked Questions

Is a mounted guillotine the same as a regular guillotine?

The choke is the same; the position is not. A mounted guillotine is finished from on top in mount, while the classic guillotine is usually finished from the bottom in closed guard.

Is the mounted guillotine a blood choke or an air choke?

It can be either. Pressing the carotid arteries makes it a faster blood choke; pressing the windpipe makes it a slower air choke. The blood-choke version is the one most fighters aim for.

Why would a fighter choose the mounted version?

It keeps them in the dominant top position. If the choke does not finish, they still hold mount, instead of risking the bottom position that a guard guillotine can leave them in.

Is the mounted guillotine legal in MMA and BJJ?

Yes. The guillotine choke is legal at all adult levels in both gi and no-gi competition, and chokes of this type are permitted in professional MMA.

Do you trap the arm in a mounted guillotine?

Usually not. The no-arm version is more common from mount, since the top position already limits the opponent’s escapes.
