For the past 11 years David Ives at Nemesis Arms has been on the leading edge of innovation in the realm of modular precision weapon systems. Recently however, he became aware of the solicitation by SOCOM for their desired Advanced Sniper Rifle (ASR). Having already been awarded the patent for the only ambidextrous rifle capable of left and right-hand bolt change in a single receiver, he decided to take his products further and labor towards meeting the requirements of the ASR solicitation. Thus resulting in the Advanced Nemesis Arms Sniper Rifle (ANSR). The ANSR is a truly ambidextrous, modular, multi-caliber, tool less take down weapon system that takes precision rifles to the next level by using interchangeable magazine wells to facilitate the changing of calibers from .308 WIN to .300 Norma to .338 Norma.
