Duration: 20:37

This review of the Knight's Armament KS-1 AR-15, presented by James Reeves of TFB TV, offers an analytical yet appreciative look at a top-tier firearm developed for a UK military contract. The KS-1 features a 13.7-inch barrel, a 3D-printed Inconel MCQ suppressor, and the new URX 6 handguard. While acknowledging its exceptional performance, soft recoil, and reliability, the review critically examines whether its high price point ($3,000-$3,500) is justified by marginal gains over more accessible high-end AR platforms.

Quick Summary

The Knight's Armament KS-1, developed for the UK's Project Hunter, features a 13.7" barrel and a 3D-printed Inconel MCQ suppressor. It offers exceptional performance with minimal gas blowback and soft recoil, but its $3,000-$3,500 price tag prompts a value assessment against other premium AR-15s.
