You should have brought a Bushmaster, excellent customer service. I bought a M4 recently and when I zero it for the first time, I just couldn't get it right. So I took it to my gunsmith, who was shooting with me, and he said that the sight is crooked. I called bushmaster, they gave send me the mailing info right away, no questions asked (no BS about how I could have broke the sight) The customer rep explained to me in detail how they will fix it so there is no confusion. Get a bushmaster next time.
