Description
The Luth-AR HG-A2 is a two-piece, round-style A2 handguard built for AR-15 rifle-length gas systems. It brings back that traditional M16A2 clamshell profile, so if you're putting together a retro military-style build or just want to bring an older upper back to a factory look, this is the part that ties it all together. It measures 12 inches, molded from durable polymer, and finished in a clean matte black.
What the Luth-AR HG-A2 Brings to Your Build
These handguards ship with aluminum heat shields already installed, which is what keeps the surface temperature manageable during longer strings on the range. The two-piece design keeps things simple and lightweight, tipping the scales at right around 7.2 ounces for the pair. That round profile and slim taper feel familiar in the hands if you've ever run an A2 rifle, and it's a comfortable grip that doesn't add bulk to the front of your gun.
Fitment Notes Before You Order the HG-A2
Here's the one detail worth flagging up front. This rifle-length version uses a triangle handguard cap, not a round one. If your current setup has a round retaining cap up at the front sight base, you'll want to swap it for a triangle cap so everything seats correctly. It's a small part and easy to source, but it trips people up if they don't know going in. Carbine-length A2 handguards use round caps, while the rifle and mid-length versions like this one are triangle-cap parts.
Simple Drop-In Swap with the Luth-AR A2 Handguard
Installation is about as easy as AR work gets. Pull back the delta ring, pop the old handguards out, and set these in place. No gunsmithing, no pulling the barrel, no special tools beyond your hands. It's a straightforward way to freshen up a worn or ill-fitting forend, or to complete that authentic clone look you've been chasing.

Frequently Asked Questions
Does the Luth-AR HG-A2 handguard use a round or triangle cap?
This rifle-length version uses a triangle handguard cap. If your rifle currently has a round retaining cap at the front sight base, you'll need to swap it for a triangle cap for proper fitment. Only the carbine-length A2 handguards use round caps.
Does the HG-A2 come with heat shields already installed?
Yes. The aluminum heat shields come pre-installed inside both halves, so you don't need to buy or fit them separately. They help keep the outside of the handguard cooler during extended range time.
Is the Luth-AR A2 handguard hard to install?
Not at all. It's a true drop-in part, so you just pull back the delta ring, remove the old handguards, and seat these in place. No gunsmithing, no barrel removal, and no special tools required.
Will this fit a mid-length or carbine gas system?
No, the HG-A2 is sized specifically for rifle-length AR-15 gas systems at 12 inches. Luth-AR offers separate mid-length and carbine versions if that's what your barrel setup calls for. Match the handguard length to your gas system before ordering.
