Easily add a picatinny rail and vertical grip to your AR15.  No need to spend hundreds of dollars on a rail system if all you want to do is add a vertical grip and a single rail to your rifle. 

This rail (approximately 6 inches long) attaches directly to the standard plastic AR15 handguards.  The included vertical grip then fits onto the rail at any position.  Fits Carbine., Midlength, and Rifle length forearms.
