The Amend2 7.62x51mm magazines in black for the SR-25 use an anti-tilt follower with long legs in the front and back to make sure it doesn't rock while being depressed. The follower has wings on the sides to give it a more consistent pressure. These magazine features allow it to be anti-tilt from front to back and side to side. Lubricant is injected into the follower's material to give an incredibly slick feel helping as rounds are being loaded into the mag. The sharp reduction in friction also feeds for more reliable feeding into the chamber.
