Outstanding company that definitely stands behind their products and services. Got 1 of their M3 multi reticles and it's been flawless. Marsh, the owner, tests the optics on many of his own firearms to ensure they can take the abuse, up to and including shottie rounds, .308, and I believe he even said .50 beowulf. Regardless, I've never had an issue with mine and would feel supremely confident that it would be resolved with ease had I ever experienced one. As stated, Marsh will tell you not to take these to combat and expect them to perform like an Aimpoint, they may, but that was never their intended purpose. They allow normal folk like you and I to have the reliability we need for our purposes at a price that we can afford. Look on arfcom for mucho information, Marsh is a daily poster there to answer questions you may have.
