HIPERFIRE is simply unmatched in performance and reliability. We have broken all of the standards in single-stage AR triggers with our HIPERTOUCH technology, and now we have done the same in our new two-stage technology. Whether you shoot competitively, train to defend yourself and your family, or you simply want to enjoy shooting out on the range, ensuring your rifle goes bang every time, without fail, is important. Our new two-stage triggers feature the same technology that HIPERFIRE has become known for. Higher hammer strike energy, soft start lock-up technology, user adjustable pull weights, mil-grade components, and precision manufacturing come together to make one of the most robust two-stage triggers available today.
