I have a civilian ARMS SIR on my RRA M4gery and the bottom rail on the SIR doesn't extend the full length of the bottom handguard. It extends maybe 3/4 of the length. However, I need one that will extend the full length and actually would really want one that extended about an inch further toward the FSB. My question is: Does ARMS make a longer rail to fit on the bottom? If not, any clues how to mount a standard picatinny rails to the bottom of the SIR? Thanks.

Thanks. I contacted Steve and he just referred me to ARMS directly. For anyone wanting to know, the ARMS #4 is 5 1/2 inches long and at a cost of $44.00. Hope this helps others.
