I'm looking at my options for installing a free float tube and so far the C-More and the FIRSH are the only ones that are realistically in my budget. I just can't afford $450 for a Knight FF handguard! $350 and under is much more realistic for me..so that narrows it down to just these two.
Also, since I have a midlength HG that sort of limits my options, otherwise I'd get a standard RAS.
Anyway...I can get either the C More or the FIRSH HG in the standard A2 length for the Dissapator look in my RR 9mm.
I understand the FIRSH adjustment, but what about the C-More? Is a special tool required in order to index the free float tube. If so, where can I get it and what is the cost?
