This is a sturdy, strong foregrip. I've got it mounted on an AK. It's short height allows it to be mounted closer to the magwell without getting in the way of the magazine coming forward and out of the well.
I did have to file a little off of the corners to let it fit the rail system I use, but it was of no real consequence.
Anyways, I'm more than satisfied with this grip and i was surprised with the quality that came from the low price.
Easy to adjust
Internal waterproof space
May not fit all rails
No other Cons
