Best warranty in the game. Had an issue, sent them a picture, and got an email same-day with tracking info for the replacement.

I recently purchased two LightCaps and two HexCaps for my Trijicon MRO and Holosun 510C, and I couldn't be happier! The quality, fit, and attention to detail are excellent. As great as their products are, their customer service is even better. It's refreshing to deal with a company that genuinely values its customers and stands behind what it sells. One Hundred Concepts has definitely earned my business, and I'll absolutely be making more purchases in the future. Highly recommend!

Highly recommend if you're tired of sunglare and want to protect your optics. Extremely great product.
