Question on durofol handguards....I've looked through a lot of posts, and was looking in Darrin's book. So, from what I'm gathering duorfol handguards are fairly common (or at least common enough) on qve coded rifles, but I'm struggling to find an ac45 rifle with durofol handguards.... Can you guys enlighten about the use of these handguards on 45 dated rifles? Thanks, Chris...
