Geissele 13.5" MK4 Super Modular Rail - M-LOK - Black
One of the most important parts of an AR-15 is the handguard. Handguards have gone through many changes over the years from the plastic clamshell-style to the free float system. Both systems give the shooter a comfortable grip while protecting their hand from the heat that radiates from the barrel. Both systems have many different designs and features built into them but the free-float system tends to be more modular. While some of the drop-in handguards offer M-Lok slots and QD mount points, most free float systems offer those same options and usually more available slots. Most handguard options have built-in options for mounting lights, lasers, pop-up sights, etc., and those that don't have them built-in may have M-Lok or Keymod options for mounting accessories.
It is recommended that a free-float handguard completely covers the gas system so please consider your gas system length when shopping for a handguard. If you wish to buy a pre-designed upper build kit equipped with a handguard please visit our AR-15 & LR-308 upper build kits page.
