Good quality, no problems. Makes a pretty loud noise when you press the button for bi-pod mode and the bi-pod slams out. Also have to ram it back up the grip to clip in. But I am pleased!
Got one of these originally for my m4. Love it. Fits solid in your hand, no wobble at all. Used a little bit of silicone lube on the action and after deplying the legs a few times it was golden. Transferred it over to my Stoner, and still have had no issues. Would definitely reccommend, well worth 15 bucks! The only way you'll get better is going real steel, which is big coin!
Not nearly as flimsy or cheap as I thought it'd be. Legs lock out fine, can take the weight of a fully loaded out rifle no problem. Much bigger than I thought, about the height of an Armalite magazine.
Great deal for $20
