What Are The Benefits of the 6.5 Grendel Round?

The 6.5mm Grendel, also known as the 6.5x39mm, is a low recoil and high accuracy round that was designed specifically for the AR-15 platform for use at ranges up to 800 yards. In many ways, it’s really just an updated version of the 6.5mm PPC. Despite originally being designed for the AR-15, the 6.5 Grendel has increased steadily in popularity over the years and is now offered in a host of other rifle designs as well, including but not limited to AK-type rifles and bolt action rifles.

When the 6.5 Grendel was originally designed, it was intended for it to be a new round that could fit into a traditional AR STANAG magazine like the 5.56 and .223 cartridges use, but while offering vastly superior performance at longer ranges. The 6.5 Grendel utilizes a shorter but also wider diameter case so it can hold more powder. This also helps it to improve its ballistics. Depending on the specific round you are using, the velocity of the 6.5 Grendel varies from as low as 2,500 feet per second to as high as 3,000 feet per second.

But while this cartridge will work with 6.5 Grendel magazines as well as with 5.56 magazines, it is not compatible with all 5.56 AR-15 parts. For example, because the diameter of the 6.5 Grendel is greater than that of the 5.56, it will not work with a 5.56 bolt so we recommend to check out our guide on the best 6.5 Grendel bolts. This also means that while the 6.5 Grendel is compatible with most 5.56 magazines, less 6.5 Grendel rounds will fit. A 30 round 5.56 AR-15 magazine, as an example, will fit 26 rounds of 6.5mm Grendel ammo.

In more ways than one, the 6.5 Grendel serves as a compromise between the 5.56 NATO and the 7.62x51mm NATO or .308 Winchester. It offers greater terminal energy than neither cartridge and superior ballistics to the 5.56 but less than the 7.62x51mm.

Why Should You Go With The 6.5 Grendel Round?

Why should you go with the 6.5 Grendel? The answer is simple: if you want to still use an AR-15 but attain ballistics superior to the 5.56, you will be well advised to go with the 6.5 Grendel round.

The only other real option will be to go with an AR-10, which is much larger and heavier than the AR-15 in order to accommodate larger rounds like the 6.5 Creedmoor or .308 Winchester.

By going with the 6.5 Grendel, you can fire bullets accurately to longer ranges than you could with the 5.56 while still using a carbine that is relatively lightweight and compact. The tradeoff here is that you will have to contend with higher muzzle flip and recoil, but this is where a muzzle brake device can come into play.

What Is the Muzzle Brake and What Purposes Does It Serve?

A muzzle brake, or a recoil compensator, is simply a device that is attached to the end of a firearm’s barrel. Its purpose is to redirect gases away from the firearm in order to counter recoil and reduce muzzle flip.

In other words, when you have a muzzle brake on your rifle, it will be much easier to shoot, and it also makes it easier for you to make faster follow up shots as well. Whether it be for hunting, competition use at long ranges, or on tactical missions, a muzzle brake simply makes it easier for you to keep your shots on target. Most sniper weapons in the militaries around the globe have muzzle brakes installed on them for these reasons.

The major downside to a muzzle brake is that it can make your rifle significantly louder, and the redirected gases can also come back at you. Be prepared for this and also make sure that you always wear hearing protection when using a rifle with a muzzle brake installed. Other people at the range may also not appreciate you shooting a louder rifle.

Another con to a muzzle brake is that it adds a few inches to the end of your 6.5 Grendel barrel. While you can reduce the impact of this by going with a brake that is lightweight, the fact that a couple of inches will be added to your rifle means that it will become a little bit more unwieldy.

One alternative to installing a muzzle brake is to port your barrel. This is when small holes, called ports, are drilled into the barrel in order to channel the gas similarly to how a muzzle brake can. This will minimize the amount that the barrel moves when a round is fired, reducing muzzle flip and recoil.

However, ported barrels have their own cons. For one thing, the flames expended from a ported barrel will be much higher than a non-ported barrel, which can visually disorient you. And while muzzle brakes also have increased muzzle flash, it will not be nearly as bad as a ported barrel is.

In short, muzzle brakes are not one hundred percent necessary for your rifle, and you can enjoy your rifle without them. They will add weight and length to your barrel, and they will cause your gun to become noticeably louder when you shoot it. But on the plus side, they will reduce the kick and muzzle rise to your rifle noticeably as well, which will make it easier to shoot for just about any application that you could need it for.

Why Should You Upgrade Your Muzzle Brake?

As previously stated, the 6.5 Grendel round is more powerful than the 5.56 but less powerful than the 7.62x51mm. It’s mainly used for long range shooting, while still being used in the smaller AR-15 rather than the larger AR-10.

However, the 6.5 Grendel produces noticeably more recoil than the AR-15. Shoot the two cartridges side-by-side, and you will see for yourself. The higher ballistic coefficients of the 6.5 Grendel comes at a cost.

By installing a muzzle brake on your 6.5 Grendel rifle, you can reduce muzzle rise and recoil by up to 50%. This will make it easier for you to more quickly realign your sights after each shot, and it also will make your rifle much more fun to shoot. If anything, installing a muzzle brake on your 6.5 Grendel will help to make recoil and muzzle flip more comparable to the 5.56 round.

In general, you should invest in a muzzle brake if any of the following apply:

  • Your rifle has a lot of kick to it, whether it be because the right is very lightweight or because you’re shooting a powerful round (or both)
  • You want to fire fast follow up shots
  • You’re willing to make your rifle louder in exchange for making it easier to shoot

Again, it’s not truly necessary to buy a muzzle brake, but it will help to create a much more pleasant shooting experience. Next, let’s dive into the top qualities that you should look for in a muzzle brake for your 6.5 Grendel.

Buyer’s Guide To The Best 6.5 Grendel Muzzle Brakes

These are the most important factors to consider when looking for a new muzzle brake for your 6.5 Grendel:


Your muzzle brake should be incredibly durable in order to ensure it long lasting. Just as you want to buy an AR-15 that you can own for life and pass on down to future generations, the same goes for your muzzle brake as well so you can pass it on down along with the AR. Several muzzle brakes are made out of aluminum, which while not quite as durable as steel, is still very strong and will not add as much weight to the end of your rifle’s barrel.

Vent Placement

Besides durability, the most important quality to look for in a muzzle brake is the placement of the vents. Poor vent placement means that the entire purpose of having the break to begin with will be negated.

Make sure that the vents on your muzzle brake are not present on the bottom of the device. If they are, this will create a force that moves upward, which will make recoil and muzzle rise even worse. Instead, the vents should be placed on the sides and on the top of the muzzle brake. This will ensure that muzzle flip and recoil are kept to the absolute minimum.

No Gunsmith Required

Your muzzle brake should not require the aid of a gunsmith in order to install on your rifle. Instead, it should either require tools that can be easily operated by you, or otherwise no tools at all. Some muzzle brakes are indeed designed to plug directly onto the end of your rifle without there being any real effort required on your part.


While a muzzle brake should be durable, it should also be lightweight. The brake should not weigh down your rifle, because doing so could make it more difficult to keep your rifle on target. Again, aluminum is a common material for muzzle brakes to be made out of because of the fact that it is both durable and lightweight.
