I have an older model Saker 556 with the ratcheting style QD mount (not the ASR) and my range session was finished with an end cap strike. The end cap is removable, so after looking down the tube the baffles don't appear to have any damage. The end cap was barely hit. I emailed SiCo warranty service. I am hoping they will replace the end cap and swap the old mount for the new ASR. However, the website says their ASR mounts are out of stock. Hopefully they have some set aside for cases like this.
