A 2-piece quad rail is a handguard system for AR-15 and AR-10 rifles, featuring four Picatinny rail sections (top, bottom, and both sides) for mounting accessories like lights, grips, sights, and lasers. It is designed in two sections that clamp around the barrel and attach to the upper receiver and delta ring assembly, often replacing standard plastic handguards. The 2-piece quad rail works with standard AR-15/AR-10 barrels, upper receivers, delta ring assemblies, and front sight bases, providing versatility and easy accessory attachment.
