I am looking at putting a bushnell 4200 6-24 atop my bushmaster.  After reviewing the needs to mount such a long scope.  Some kind of extension to the front will be essential.  

I see A.R.M.S. is the answer as they produce a whole line of exentions and rail accessories.  Where can I find a comprehensive guide to what the build so I know what to look for either here at EE or on the web?  

I could not find any kind of official website or a very informative supplier.  Any help appreciated.

go to google.com and search "ARMS mounts."

have they updated their www site? Last time I was there it was in need.

Last I checked it had been updated some. Still had some stuff missing though.

Unfortunately,

I don't think it has been updated with all of the new products although I do see references to the new model SIR's.

Wes or Paul can, I am sure answer any ARMS questions you may have far better than the ARMS website ever could.  Not everything they deal in is on their site so don't be surprised but ask them and they can help!
