Best M4 Sling Buying Guide – Should You Go For A One Or Two Point Sling?

Your choice of sling design is very important. It may seem that selecting the best M4 carbine sling is an easy choice. Meaning, just about any will do. This really is not the case.

A little research will go a long way in terms of ensuring you get the best designed sling. One that most suits your shooting habits.

Here is a brief explanation of both types of sling:

Basic Difference Between These Two Sling Types

  • A one point sling connects to just one place on your weapon.
  • A two point sling connects in two separate places.

Both styles offer potential advantages as well as disadvantages. Let’s explain:

Single Point Sling

Connected by a single point to your rifle means you wear the sling over one shoulder. It should be noted that wearing recommendations state that you have this diagonally placed across your chest. This is because by wearing the sling diagonally, your rifle weight is distributed across a larger surface. This means the weight is less likely to cause discomfort, particularly when on long weapon hauls!

A Major Advantage

Using a single point sling means that your rifle will constantly be in the “ready” position. You will be able to grasp it and adopt the shooting stance in no time at all.

A Potential Disadvantage

Wearing the sling in such a position means your rifle can constantly move while you are walking. When you have the rifle positioned to the front of your body, it is prone to constantly knock against your chest or stomach. This can be irritating! Of course, in this position, your rifle is constantly within very easy reach.

Wearing the sling across one shoulder means you feel the weight more on the chosen shoulder. The other factor is that dependent upon length, it can also knock against your legs. This can certainly interfere with your natural stride.

There Is A Solution (In Fact There Are Two!)

To solve this sling/rifle movement issue, you can:

  • Strap the sling to your chest. This will prevent any great movement.
  • Wear a cuff on a tactical belt. This type of cuff is designed to keep the rifle at your side and prevent movement.

Two Point Sling

This is by far the most popular design. It is also one that manufacturers prefer. The first advantage here is that choosing a two point sling gives greater choice in makes and design types.

Connecting to two separate rifle points means you can wear it either over one shoulder or across your chest. The carrying position will be dependent upon your preferred shooting position.

A Major Advantage

Use of a 2 point sling works to actively stabilize your weapon when you are shooting. This is because choosing the best 2 point M4 sling will allow for ease of adjustment.

When aiming, you can tighten the sling around your body. This makes your rifle far more stable.

This technique really does assist shooters who need to hold a sitting or prone stance for long periods. By taking advantage of your sling, you are effectively using it as a shooting brace.

Shoulder carrying means ready for use

If you prefer to have your sling on one shoulder, then carry it over your non-dominant hand shoulder.

By doing so, you will always be carrying your rifle in the “low ready” position. This means transition from carrying to shooting position is achieved with speed and ease.

A potential disadvantage

This potential disadvantage should not bother most shooters, but it should be pointed out. When using a 2 point sling, you will need to unsling your weapon when changing shoulders.

Having explained the differences between one and two point sling use, we feel it only correct to make one additional benefit of an M4 sling purchase very clear.

A Best M4 Sling Is Not Just For Ease Of Weapon Carrying!

Yes, the main purpose of a best, personal use M4 sling is for ease of carbine carrying.

Having your rifle slung over your shoulder will free your arms for other purposes. It also goes without saying that a sling will allow for far easier weapon carriage.

This means that when it is time to shoot your arms will be far less tired. A sling can also give support when tracking or monitoring your target’s movement over an extended period. This is because your back can take the constant strain off your arms.

But, you should also consider that in emergency or survival situations a best-made M4 sling can be a real bonus. You can fully utilize them to become tourniquets should one be required. Additionally, you can turn them into snares or traps and also make use of them to construct a temporary shelter.

So What’s The Best M4 Sling?

We feel that two point slings offer more advantages to more shooters than the one point versions. And you can also rest assured that a best, well-designed M4 two point sling will not interfere or restrict your movement.

It will allow full use of both hands when other tasks are the order of the day. It will also afford quick, easy rifle access as and when needed. With these factors in mind, we must recommend the:

STI 2 Point Rifle Sling – Adjustable Gun Sling with Fast-Loop and 1.25 inch Webbing for Hunting Sports and Outdoors.

This sling is a class above in terms of the high quality, tube-woven nylon strapping that gives easy thumb-loop adjustment.

These adjustments can be made when stationary or on the go. Another plus? This best M4 sling will certainly come in handy should you find yourself in a survival or emergency situation.
