Well It happened and someone broke one at last.
Name and other stuff withheld but a replacement cheek rest was sent out today at N/C.Karsten, the damage was due to my error - not your product. During a halt in a night training MRAP convoy movement, I failed to fully clear equipment and pinched the cheek rest between an approx 800lb door and the vehicle body. The cheek rest deformed slightly, but most noticable was what looked like an inch long crack along the top of the rear portion of the saddle. We had to pry the cheek rest off the weapon and didn't try to reinstall it, only the bolts were reinstalled. I believe the flex in the cheek rest prevented damage to the stock. I no longer have the damaged cheek rest, but need to get a replacement to the unit.
Again, my error, and I'll gladly pay for the replacement. Please advise.
