I was looking at Shotgun News and saw that KY Imports has Bushmaster A2 Postban Lower Receivers for $259.99. The price seems really good, and that makes me a little nervous. Does anyone know if these lowers are legit? I would like to make sure that they are not factory rejects or anything like that.
I have one other question. I have been looking at a Rock River Arms upper through Sable Company. Does anyone know if RRA chambers are 5.56 or 223? I mainly shoot surplus ammo, so I want to make sure I get the 5.56 chamber.
Thanks for your help.
Pete in NH has RRA lowers, www.ar15.com/forums/topic.html?id=95047
RRA is mil-spec 5.56 and Donnie is the man for their uppers. I got a DCM/CMP RRA upper from him.
