Fantastic Scope by Greg, Verified Owner, July 3, 2024
Bought this for my Daniel Defense DD5V4 and it’s been great. Haven’t had a chance to go hunting yet but it’s performed well at the range over the last year. The BDX system is awesome from the scope to the range finder and the app.

sig sierr6bdx by Forrest Tidwell, February 23, 2024
