Best Barrels for .458 SOCOM (2020) – Evaluated

When looking for the best .458 SOCOM barrels, it’s always essential to look beyond mere compatibility. With a wide range of lengths and other options available for the best .458 SOCOM barrels, it isn’t a mere issue of compatibility anymore.

Factors to Consider for a Great .458 SOCOM Barrel

Length

Short barrels – Although the .458 SOCOM ammo is pretty powerful, it is still widely used with short-barreled rifles and pistols. Some shooters even use 7.5’ barrels that chamber the .458 SOCOM on shooting ranges. Realistically speaking, since the SOCOM rounds have been optimized for 9.5’ barrels, using a 7.5’ barrel isn’t as extreme as it looks.

Besides that, short barrels also allow you to maximize your maneuverability if you are only shooting on shorter ranges.

Long barrels – These are great if you want to achieve the maximum velocity of the .458 SOCOM round to reach longer distances at the cost of some maneuverability. That said, any barrel that goes beyond 16’ would give almost no benefit in terms of velocity.

Legality

Before purchasing any barrels, you should always make sure that the barrel lengths are in compliance with your state’s gun laws. You won’t want to end up getting into trouble because of this.

Durability

If you didn’t know, the .458 SOCOM round packs a pretty heavy punch and hence, you would want to look for a durable barrel without sacrificing other features.

Compatibility

This should go without saying. Whether your barrel would support the accessories that you already have in mind is always essential. Hence, you should always double-check this part.
