The LBE Unlimited ARHCR handguard cap is a US-made AR-platform accessory designed to cap off your round handguard where it meets the front sight base. If you're running an original-spec or aftermarket round handguard on your AR-15 or similar platform rifle, this steel end cap fills the gap cleanly and protects the open end of your tube. It's a small detail that makes your build look finished and prevents debris from collecting inside the handguard.
LBE Unlimited has built a reputation for solid, domestic gun parts that work without fuss. This cap fits .750-inch diameter barrels—the standard diameter you'll find on most AR-platform front sight bases and round handguards. The M4 cuts on the cap allow it to integrate with standard Picatinny rail systems and AR accessory mounting patterns, so it plays well with the rest of your setup.
Whether you're assembling a retro build, refreshing an older rifle, or just want a proper end cap instead of leaving your handguard open, this is a straightforward, made-in-the-USA solution. It's black steel, durable, and built to last as long as your rifle.
The ARHCR is designed for .750-inch diameter barrels, which is the standard size on most AR-platform front sight bases and round handguards.
Yes, this cap is designed for AR-platform rifles. The M4 cuts allow it to integrate with standard Picatinny rail systems and AR accessory mounting patterns.
The handguard cap installs at the end of your round handguard, behind the front sight base, to cap off the open end of the tube.
