This is for left handed rifles.
When designing these strap on cheek pads, Tactical Operations listened to the operators in the field and included some of the latest features. Not only are these made of rugged canvas material and have a padded suede type cheek pad area for comfort and no slipping, but they also are able to hold 8 rounds, typically 5 standard match rounds and three specialty rounds such as glass busters, AP or tracer, or what ever the team SOP my dictate. There is also a separate pouch area in the rear to hold a range card or other data for easy access.
These packs are very high quality, made in the USA, and also included a longer front strap for stocks such as the A5 and others that do not taper and may require a longer strap to properly secure it in place.
