AR barrel identification - 05/05/12 04:50 PM
I just took my AR apart and was wondering if anyone could tell me what the numbers mean? I was told when I bought it that it was a Rock River 1-8 twist. the only markings found were close to the breech. Thanks
It is stamped 216S/K

Does it have the twist and caliber marked on it? I dont think I have ever seen a RRA that isnt marked with at least the caliber and twist.

No, just the marks bu the breech as you can kinda see from the picture. that's why I'm asking, maybe I was "misinformed" ..... Thanks
Is that possibly a "1" after the other numbers? Does "model 1" mark theirs like that?

Thanks everyone, I called Rock River tech support and was informed that it is exactly what I thought I had purchased.
16" Mid length gas Stainless Heavy match barrel. 1-8 twist
Wylde chamber.
216 is the barrel identification
S is for stainless
K is for something in-house@ Rock River
and the 1 is for who assembled the upper.
