  Doug, not personally but, there are vendor reviews and you tube reviews you can check out that run without issue under many different AR brand/lowers. The trigger group in the lower is just a small part of the overall operation. Most function happen within this upper. Cheers and stay safe!

  A:

  Bruce, yes SIr, this will work no issue. If your lower is a complete lower roll with what you got. If not, any standard AR Trigger group will work from basic to Geissele, your choice depending on your needs/wants.
