Just spoke with Mark at LaRue about a Mid-length handguard. He said they should be available in about 3-4 weeks. They are tied up cutting the 7.0's & 12.0"s for the moment, but mentioned that they havent had too many requests for the Mid-length as of yet to make them a priority. So... mid-length AR owners call'em up!!! Good people to deal with, they do listen to what you want.
Anyone interested in a Mid-length S.I.R. #58??? When the LaRue comes out, I plan to do the switch-a-roo.
