| I'm considering a RRA upper assembly for full auto use. But I've read RRA chambers are .223/5.56, not full 5.56 NATO. Do they run with no problems in FA or does the chamber need to be reamed to 5.56 spec? Thanks. |

It will be fine I use my RRA upper in full auto all the time. You just need to get a full auto carrier.

The upper actually comes with a FA BCG but I'll be using my SP1 carrier with my RLL. From what I understand, the RRA .223/5.56 chamber is a little tighter than full 5.56 NATO. But your's is the kind of real-world feedback I'm looking for. I suspect this is like asking if M4 cuts are necessary. Thanks! |
| Really your RRA upper came with a full auto carrier. If so thats great I have 4 RRAs . 2 I use (both semi carriers) and 2 newer ones just sitting in the safe. I will check them outwhen I get home to see if they have FA carriers. I am builing up 2 M16s lowers and need FA carriers. |

It's an upper on the equipment exchange that includes an LMT FA carrier and a DD rail that I was considering buying. Had to pass on it 'cause a good deal on a 7.62x39 upper came up and I already have a 5.56 NATO Bushy upper. Sorry for the misunderstanding. |
