Rankin Industries 15.5 inch Handguard

Product Description

The Rankin Industries 15.5 inch handguard is an AR-15 pattern free-float handguard from Rankin Industries, Western Sport’s own brand. This length suits builds using a mid-length or rifle-length gas system and provides a long sight radius for magnified optics or backup irons.

The 15.5 inch length extends almost to the end of an 16-inch barrel, leaving just enough muzzle clearance for most muzzle devices. It gives you maximum rail space for accessories while maintaining balance.

This handguard is part of the Rankin Industries line, Western Sport’s own brand of AR parts and firearms.

How a 15.5 Inch Handguard Fits Your Build

A 15.5 inch handguard is the longest practical choice for a 16-inch barrel, the minimum legal length for a rifle barrel in most states. The handguard stops short of the muzzle threads, allowing you to install a muzzle brake, flash hider, or compensator without interference.

This length works best with mid-length or rifle-length gas systems. It will not fit over a carbine-length gas block unless the gas block sits under the handguard, which requires a low-profile or set-screw design.

Longer handguards shift the weight forward, which some shooters prefer for steadier offhand shooting. They also give you more room to position lights, lasers, grips, and hand stops exactly where you want them.

What Makes Rankin Industries Handguards Different

Rankin Industries is Western Sport’s own brand, and every piece is selected to the same standard used in the custom rifles and NFA builds we deliver from our shop.

When you buy a Rankin Industries handguard, you are buying from the same people who built it. That means you can call us with fitment questions, installation help, or custom work to match the rest of your build.

Installation and Compatibility

Free-float handguards replace the standard AR-15 handguard and barrel nut. They attach to the upper receiver with a proprietary barrel nut and do not touch the barrel, which improves accuracy by eliminating pressure points.

Installation requires a barrel nut wrench, an armorer’s wrench, and a torque wrench. Send us a message to confirm fitment and discuss installation options for your specific upper receiver and barrel combination.

Frequently Asked Questions

Q: Will a 15.5 inch handguard fit a 16 inch barrel?

A: Yes, a 15.5 inch handguard fits a 16 inch barrel with about half an inch of muzzle exposed, leaving clearance for a muzzle device. This is the longest handguard you can use on a 16 inch barrel without covering the threads or muzzle device.

Q: What gas system length works with a 15.5 inch handguard?

A: A 15.5 inch handguard works with mid-length and rifle-length gas systems. It also fits carbine-length systems if you use a low-profile gas block that sits under the handguard. Send us a message to confirm compatibility with your specific barrel and gas block.

Q: Who makes Rankin Industries handguards?

A: Rankin Industries is Western Sport’s own brand. Send us a message with any fitment or specification question and we will answer it directly.

Q: How does a 15.5 inch handguard compare to a 12 inch or 13 inch?

A: A 15.5 inch handguard provides more rail space for accessories and shifts weight forward, which some shooters find steadier for precision work. Shorter handguards like 12 or 13 inch models are lighter and more compact, better for close-quarters use. The best choice depends on your barrel length and how you plan to use the rifle.

Q: What do I need to install a free-float handguard?

A: Installing a free-float handguard requires a barrel nut wrench specific to the handguard design, an armorer’s wrench, and a torque wrench to tighten the barrel nut to the correct specification. You will also need to remove the existing handguard and barrel nut from your upper receiver.
