Battlefield 3 Underslung Rail Guide

In this Battlefield 3 Underslung Rail guide, you will learn what the Undersling Gun does, how it is unlocked, and what the best uses for it are.

Battlefield 3 Underslung Rail - Overview and Function

The Underslung Rail is one of the basic primary weapon accessories and is used to mount specialty weapons (particularly certain shotguns or ballistics like grenade launchers) to your gun. This makes it faster to switch between your gun and your explosives launcher.

How to Get the Underslung Rail

The Underslung Rail is the default option on many guns. If you do not see the Underslung Rail on your gun of choice, it is likely that the particular weapon in question is unable to use this particular accessory.

Downsides to Using an Underslung Rail

The main downside to using the Underslung Rail is that you cannot equip a Foregrip at the same time. The Foregrip is a great accessory and really increases the accuracy of your gun throughout longer fire-fights.

Battlefield 3 Underslung Rail Strategy

The reasons for using the Underslung Rail are certainly the most straight-forward of any of the weapon attachments: so you can access your Shotgun or M320 and related other explosive weapons easier.

As a result, if you use your grenade or rocket launchers (when applicable) frequently, you will want to use an Underslung Rail to make using them easier. If you are not the type of player who makes much use out of ballistics, then there is no real point behind this attachment for Engineers.

Likewise for Assault players, you may want to use the Underslung Rail to attach a Shotgun. This will naturally make you more effective at short-range combat.

Of course, you actually have some of these ballistics or shotguns unlocked or be playing an Engineer or Assault class in order to actually make use out of this attachment.

Another good reason to use the Underslung Rail is to use Smoke Grenades with the M320. These are probably the most potent weapon in the entire game for Rush mode strategy. What you do is launch smoke grenades at an objective you are trying to cap. Your team can then run in and cap it and your enemy will not be able to stop them since they cannot defeat them due to smoke.

Battlefield 3 Underslung Rail Guide Conclusion

Using this primary weapon attachment is simple: if you want to use an M320. If you do not have any explosives unlocked or the M320 is an entirely foreign weapon to you, stick to something more useful like the Foregrip or Bipod.

If you are an Assault player who wants to be stronger at short-ranged combat, this also makes a good choice over the Foregrip. The Foregrip is best for Assault players who want to stay at range. You can switch between these two and customize your gun depending on the map you are playing on.
