The bag fits two extra mags nicely. The 3 enteral Velcro straps work well to hold 1 1/2 inch tall cheek rise placed under the pack to get the perfect sight path.
The bolt can be removed w/o taking taking the pack off. Good material, nice finish on the cheek rest. The leather is soft. I wood recommend this to a friend.
Looks great on my Sako 7MM Mag.
