Installed on ar and ak - UTG Pro Ergonomic Ambidextrous Vertical Foregrip

For the price what can you say but AWESOME that is why I took the chance and purchased two with no regrets. Save your hard earned money and buy this over any of the other same size more expensive ones. It goes on the rails snug and once you clamp it down there is no free play whatsoever. Great feel with a soft but tacky surface.
