I have a Rock River 223 varmint. Shoots 3/4" < with what ever you can get in it. I ordered a RR lower Jan.14th, finally got it Aug. 16th. They are somewhat back ordered. Must be some indication of their quality and success. But they have become quite arrogant. They do not answer phone or e-mail. I'm sure how I feel about their products but their customer service sucks. Not good for future business.
