What is a Quad Rail?

Quad rails are a type of handguard for assault rifles and carbines. They feature four Picatinny rails that run along the top, bottom, and sides of the handguard.

These rails enable you to attach various accessories, such as lights, lasers, grips, bipods, and more. The quad rail design offers expansive real estate for mounting accessories, making it a popular choice for tactical and competitive shooting applications.

However, it’s also bulkier and heavier compared to other handguard options, such as the M-LOK and KeyMod systems. Therefore, you should consider the intended applications for your firearm; competitive shooters, for example, may require a more streamlined platform than others.

What is a Quad Rail Handguard System?

A quad rail handguard system is a series of accessories that attach to the upper receiver of an AR carbine or assault rifle. For example, the QRHS on your firearm may include a pistol grip and a scope, while soldiers may require a quad rail handguard system with a tripod and IR lighting.

What Size is a Quad Rail?

Quad rail handguards come in different sizes, depending on the length of your carbine or assault rifle. The length of the quad rail system determines the number of attachment points and accessories you can mount.

According to experts, you should select 6¾” rails for carbines, 8½” quad rails for mid-length rifles, and 12” rails for full-length rifles. However, handguards are also available in other lengths, such as 7-inch quad rails and 10-inch quad rails.

Do Militaries Use Quad Rail Handguards?

Yes, militaries do use quad rail handguards. They were originally designed for military applications, after all, and they’ve since become a standard feature on many modern military rifles, including the M4 and M16.

In fact, today, M4s and M16s are equipped with quad rail handguards as standard, providing soldiers with a secure and customizable platform for attaching accessories.
