Gripknife is a revolutionary foregrip with one major advantage-it can save your life. That simple. With the push of a button, your grip instantly becomes your knife. In close-quarters, should an enemy try to come in-between you and your rifle, you’ll have the option to surprise them by transitioning from your primary weapon, to employing an edged weapon, all in the blink of an eye-nothing is quicker. No OTF knife is stronger. Nothing more effective. Period. Made in the heart of America. www.GRIPKNIFE.com
