https://stream.echo6.co/videos/watch/a61abbff-a8d2-4ddb-adbe-47d5f7653e81 The very first test runs of serial numbers 1-50 of the KE Arms KP15 polymer lower have been through by-hand secondary operations and are out at the 2g-ACM match for field trials a mere few days after they were vibration welded. In this video we test three of the very first test KP15 lowers by running them through the match in three different configurations. We discuss everything that has progressed so far to get to this point and what the next steps are. InRange is entirely viewer supported.
