Source? While I would love to see that happen you can't even get a factory SBR 16 or 17 so I don't see that happening anytime in the near future. But hypothetically lets assume it does get released. There is still a good chance that we won't see it in anything other than 5.56 and I really like the idea of this in 300BLK.There might be a rumor going around fn is gonna put one out for civies.
That doesn't really add much to the conversation...fact is they are the only ones offering this setup.I would not buy anything from that manufacturer, that's my, and some others on this forum, opinion.
