I have a Burris Fastfire 3, which I failed to loctite when mounting. It fell off from about 4 feet and landed on the sun shade.
I mounted it again, and the dot worked only intermittently. Called them and the CS rep apologized to me for my inconvenience,
sent me a ups shipping label, and started my claim. I had a BNIW in hand in under 3 weeks from drop off at ups.
Fantastic service. I would definitely buy their products again.
