AR15 M16 Quadrail Handguard

Rifle-Length Quad Rail

The NcStar AR15 M16 Quadrail Handguard replaces the plain factory handguard on a rifle-length AR-15 or M16 with four full-length accessory rails. It gives you room to mount a light, laser, vertical grip, bipod or backup sights without clamping anything to the barrel. It suits shooters who want to add accessories to a full-length rifle without replacing the barrel nut or other upper receiver parts.

Features

• Quad Picatinny Rails — Rails run along the top, bottom and both sides, using the picatinny standard: a slotted mounting rail that most modern optics, lights and grips clamp onto.
• Rifle-Length Design — The handguard is sized for the longer rifle-length AR-15 and M16 configuration, not the shorter carbine or mid-length systems.
• Two-Piece Construction — Upper and lower halves seat in the same position as the original handguard pieces.
• Numbered Rail Slots — Every second slot is marked with a white number, so you can note where each accessory sits and put it back in the same place after removal.
• Ventilation Cutouts — Rows of oval slots along the body let heat escape from the barrel and keep the overall weight down.
• Hex-Screw Rail Mounting — The rail sections are held to the body with recessed hex screws placed along their length.
• Black Finish — A matte black finish matches standard AR-15 uppers and receivers.
• NcStar Branding — The NcStar logo is marked on the side of the handguard body.

Fit and Compatibility

This handguard is made for AR-15 and M16 rifles using rifle-length handguards. Check your gas system and barrel length before ordering, since carbine and mid-length rifles need a shorter rail. The top rail lines up with the receiver, so optics and sights mounted along it stay level with the upper.
