How to Install a KAC Vertical Foregrip

The vertical foregrip made by Knight's Armament Company (KAC) offers additional shooting stance and control options to AR15-style, semi-automatic rifles. The KAC vertical foregrip is one of variety of options designed to mount on aftermarket foregrip rail adapter systems. These upgrades add a Picatinny accessory rail in place of the stock AR15 foregrips. The system duplicates the standard equipment on the U.S. military M16A4, which is issued with Knight's foregrip rails and vertical foregrips. Made of molded polymer with a steel center tube, the KAC vertical foregrip is available in black or green. It installs on any Picatinny rail without tools.
