The Only Buying Guide You’ll Need

Barrel Length


Shorter barrel lengths are easier to handle than longer barrels. However, you do have to consider that it has a higher operating pressure in shorter barrels.

What’s more, there is an increase in the noise, and the parts wear faster in shorter barrels. 

In other words, the use of a suppressor is a requirement for short barrel length. As the sounds are unbearably loud for shorter barrels, you can’t use it indoors without protection. 

You can shoot shorter ranges with the lightness of the firearm, which makes it a good option for thick brush hunting and for home defense. 


A longer 458 SOCOM barrel gives you an added velocity and distance, meaning you can hit your targets at longer distances. However, in exchange for velocity and distance, longer barrels are heavier with less maneuverability.

You do have to keep in mind that a longer barrel that’s lengthier than 16-inches has no added velocity benefits, so if you don’t have any reason to purchase a barrel beyond 16-inch, don’t buy it.

You will only purchase a unit with a longer barrel because of the compatibility of the gun accessories you already have.


Look for 458 SOCOM barrels that are made with 416 stainless steel to ensure durability. Avoid purchasing barrels that have a 4150 GBQ mil-spec if you are after longevity. While you do have to pay more, it does last longer. 

If you are on a tight budget, and purchasing a 4150 GBQ mil-spec is your only option, make sure that the barrel has been enhanced with nitride treatment, so it gives you comparable durability.

Special Features

Fluted Barrel

These fluted barrels are often more cosmetic than functional. However, if you value aesthetics and want a sleeker look, then a fluted barrel is for you. 


Rifling Bore Protection

A .458 SOCOM barrel that has a target crown helps in the longevity of the performance. It is connected with rifling inside the bore. As a result, it enhances rifle accuracy as well over long-term usage.

Use of Suppressor

Regardless of the barrel length, a suppressor or muzzle brake for 458 SOCOM is worth considering, especially if you have a shorter barrel. 

Your choice of the barrel has to be end-threaded, so you can use a suppressor or place one in the later future. 

For a 10.5-inch barrel length, you need a suppressor to suppress the loud sound of the gunfire. While it doesn’t eliminate it, it’s essential to protect your ears. (1)
