What is a Single Stage Trigger?

A single-stage trigger is the most basic and primitive trigger used in guns. As the name suggests, a single stage trigger simply pulls off the lock when you push it and releases the spring of the charging handle. This causes the firing pin to hit the cartridge. The trigger bow is directly connected to the sear.

Single stage triggers have been used since the invention of guns. They are easier to adjust and crisper than their counterparts.

Single-stage triggers are very predictable because you know the amount of force you need to fire a shot. These triggers have a heavy pull weight, making them great for accurate shooting. The pull weight varies from a half-pound to seven pounds. Pull weight refers to the amount of pressure with which you need to pull a trigger to make it function.

Single-stage triggers are very common among AR-15 rifles. As a matter of fact, almost all military rifles are equipped with single-stage triggers. This makes it obvious that these type of triggers can be used in life-or-death situations.

What Are The Best Uses Of A Single Stage Trigger?

There are quite a few uses of your AR-15, such as home defense, hunting, shooting competitions and practice. Single stage triggers have their own effectiveness and importance in different situations. So let’s take a look at them one by one.

Single-stage triggers with light pull weights (less than 4 lbs) are good for hunting and 3-gun shooting competitions. That’s because light pull triggers have a minimal amount of travel before they break as well as minimum overtravel. This leads to faster follow-ups, which means quick and precise shooting. Single-stage triggers have a simple design with quick operation.

Home Defense

Single-stage triggers have been used by the military for decades. The reason is its simple and quick operation. These triggers offer a constant resistance. Pulling them once means a shot is fired.

Additionally, this type of triggers hasno overtravel. This allows for faster follow-up. That means you can shoot rounds quickly. Additionally, single-stage triggers won’t confuse you while you are in a stressful self-defense situation. Just pulling the trigger makes the break, letting the bullet fire off. You don’t have to worry about the change in resistance that comes with dual-stage versions.



The type of trigger you use for hunting totally depends upon individual preference. Some people like to have triggers with constant resistance while they aim and shoot. For short-range hunting, single-stage triggers are generally the best.

But you might want to think again if you are aiming for long-range targets. You don’t want to pull the trigger accidentally while you’re hiding in the bushes and stalking your target. That’s where a single stage trigger with moderate pull weight is helpful.

Shooting Competitions

Single-stage triggers are the best for 3-gun shooting competitions. For others where more precision is required, you might want to have a different type (two-stage of course). You’ll have to engage different targets at different distances and shoot in various positions. For situations like this, you’ll need a trigger that is constant and shoots quickly. That’s where these single-stage triggers come into play.

Target Practice

The most important factor to note here is the range you are shooting at. For short range practice, single-stage triggers offer a constant resistance to help you take repetitive clear shots. For long-distance shooting, where a feather-light pull weight is required, you might want to customize your single-stage triggers or go with dual-stage triggers.
