Magpul has recently added a full length model to their popular MOE Handguard series for use on AR style rifles with direct impingement or external-piston gas systems. The handguards are made of light weight polymer and are easily installed by anyone competent enough to replace the standard AR handguards. Probably easier given the finger bashing, sweating, and swearing the standard guards take. Slots at multiple locations along the handguard allow for the attachment of Picatinny rails making the MOE a reasonable alternative to pricier aluminum rails for the budget minded shooter. I wouldn’t go mounting any optics to it, but they should suffice for mounting accessories like lights, hand grips or bipods.
