I don't think it's the worst attachment, but it's definitely not a good one. You essentially turn it into a Type 25. That completely takes away the range advantage of firing it in burst. It's almost as bad as using rapid fire on SMGs.
It's decent, but there is no way that the stock is not the best attachment for this gun, and all ARs for that matter. --- GT:lethaalhawk "Trouble with the trolley, eh?"-Pelican from trolley activity in Spyro 2
