So initially when i brought my first TD grip, i thought it might be a little to small and uncomfortable. But surprisingly, after using it on my Aug A3, it has been amazing, My only gripe with it on the Aug is the plastic mount for the picatinny rails doesn't fit properly on the Aug, so i had to remove them, It causes the grip to feel a little loose, but its not to bad. I have since brought a second one for a Wells m4 CQB, and it goes hand in hand with that blaster.
