It seems that once the RASII came out it was gone.  I haven't heard much about it lately.  Any Mil. using the item? etc. etc.  Of course I could have missed some good posts on it.  I did see the RASII vs.  SIR threads(all of 'em) but I thought it was gonna be the next BIG thing.  Has the New SIR items comanded all the attention?  Seems like the URX was right behind the RASII kind of leaving it in the lurch.  Any comments would be great!

Well I have the KAC RAS II and the ARMS SIR #45.  For some reason I prefer my ARMS SIR better.  It also looks 'cooler'.  [:D]
I found the SIR to be sturdier than the RAS II.  Which ever you get you won't go wrong.  The RAS II can be purchased from Wes at MSTN and the SIR can be purchased from Bushmaster and maybe MSTN too.
