It's actually I think about another .5 to 1 inch longer than the standard 16 inch barrel with the birdacage on. So that also leads me to believe that is was a post ban turned after the death of the AWB. The RRA is awesome I have no complaints what so ever, I was thinkin that he took off all of his Bushy Tele stocks because he had another Bushmaster with an RRA stock, but this one had the light barrel with the phantom or izzy brake on it as well as the bayonet lug, reguardless he gave me a good price on it and threw in a few extras because I do alot of buisness with him. Just wanted your guys input. It was NOT a NIB rifle just for the record. But is was not used either the dealer I just changed out the stocks I suppose. The rifle it self is emmaculate, it is obviously brand new. I was just curious about the RRA stock myself because when I got the Bushmaster "new rifle packet" you know with the sling, 10 rd clip, instruction manual, and small catalogue book they were selling stuff for which they didn't even make the rifles for like Mini 14 mags and what not. So I thought maybe they sell RRA stuff. I thought it was slim to none anyway but thanks for the info guys.
