Same here, it works well on everything but my Ruger mini 30 in 7.62x39. That rifle will not cycle the Hornady subsonic rounds.I have an Omega 300 and it is impressively quiet with my 300 BO and 762/39. That is the only one I have shot. Just wish I could get my AR to cycle subsonics with the 762/39. I like the mounting options and I also like the included flash guard that help when I am using night vision.
