so far i have the redlion quad rails/ front sight and i notice that if i give it it a gentle twist, the whole foreend will twist 1-2mm left and right. it seems like it is has play where the square bolt is. im sorry if i cant be more specific. has anyone had this problem. i feel like i cant get my red dot sighted right with these

Sorry, I don't own one to know. Have you called Red Lion? 1 or 2 mm really isn't much movement for a Sub. While accurate, they're not exactly tack drivers with factory ammo anyway. But I understand your concern.
