Choosing the right barrel is important. Any shooter knows that fact. Specifically, the barrel is the one that contains the expansion of gas generated by propellants when you are firing your rifle. In a sense, a good barrel improves the accuracy and power of the projectile by maintaining the proper muzzle velocity.

Since we are talking about 6.5mm Grendel here, it should be a given that the barrel you choose for your rig is compatible with it. Take note that this cartridge from Alexander Arms is relatively big. If the barrel can't accommodate its size, then things would end up in a catastrophe. If you want to avoid such predicament, then you need to trust the following barrels instead.

One of the top manufacturers in the rifle industry today is the JP Enterprises. They are an excellent source for guns and different gun parts. If you have one of their rifles, getting this barrel is highly advisable.

Specifically, the JP Supermatch comes from the rugged 416R stainless steel. It has also been treated with cryogenics to ensure the predictability of cold bore shots while keeping the thermal drift at a minimum. The barrel is also air-gauged and lead-lapped, too, for maximum durability and ruggedness. With all of these features present, you can guarantee that the JP Supermatch has a superior lifespan and accuracy.

Barrel Basics: What to Consider

If you are wondering what constitutes a great barrel, then you should check this short but comprehensive guide I made. I am pretty sure that you can learn a thing or two here.

Material

Most of the barrels today came from different materials. Some of them are carbon fiber, blued steel, and stainless steel. These are just the options that you can find on the surface. If you dig deep, you can find other models made from sleeved titanium or nickel-based alloys.

Each of these materials can produce different interaction. The combination of each of these materials affects the vibration and weight of the barrel. Of course, the lifespan and heat control that they have are all on different pages, too. You can never have a combination to be "standard" of the industry because will reprimand you for that.

There are also these things called coatings, in which is applied to the material to lengthen the barrel life further. But of course, simple people like me avoid them because they are costly. Other competitive and military shooters do opt for them. However, I can say that these barrel coatings are not entirely necessary.

For starters, I can suggest that you pick stainless steel barrels. Well, the reasons are pretty simple. First, they are very accessible. Second, they are immune to rust and corrosion. Lastly, they have are slightly better than blued steel when it comes to lifespan.

Rifling

Rifling is about configuration. The sky's the limit, as they would say on the field. You can opt for button rifling, hammer-forged rifling, or cut rifling. There is also those unique polygon type of rifling that is common on many Heckler and Koch barrels. But do all these things matter?

Well, the answer is quite difficult to put in everyone's agreement. I have read some statements that rifling is just an external factor for it to affect the ballistics of your ammo. But on the flip side, some suggest that rifling with slow twists and few grooves can impact the outcome of your shot.

Twist

The twist is an important factor in choosing a barrel. In fact, I always check the twist of the barrel before anything else. If your barrel has a slow twist, the bullet will never achieve this thing called stability. If the twist is fast, the accuracy will be at risk. For cartridges like 6.5mm Grendel, the 1:8 twist is a reasonable choice already.

Barrel Length

The dimension of the barrel is also a crucial consideration. Obviously, barrels with longer length have better accuracy than their short counterparts. Since we are talking about the 6.5mm Grendel here, you should opt for long barrels. After all, the particular cartridge is ideal for long-range applications. But of course, there are still some repercussions when choosing a long barrel. Such of these are its weight and its portability.

Final Verdict

Considering all the barrels that I have featured, the JP Supermatch Barrel should come first on your checklist. This particular barrel is suitable for 6.5 Grendel. It is durable and has a decent cooling capability. It is stable due to its length and has a long barrel life due to its stainless steel construction. In my opinion, it is the best 6.5 Grendel barrel that you can get for a fair and reasonable price.
