Lens/ customer service - Shield Sights Reflex Mini Red Dot Sight

I got the RSMc when the hellcat first came out and at first it was amazing. I thought I just cracked the lens myself, so I purchased another one and made sure I was careful. The 2nd one cracked also, turns out the recoil from shooting about 250 to 300 rounds makes the lens weak and cracks. The lens is the only part of the optic not covered under warranty so you have to pay 90 USD to send it back to the UK and wait countless months before even getting customer service to replace or "fix".
