I purchased an older style KAC QDC FH (like pictured) and have some questions regarding suppressor compatibility:
I pinned/welded through the hole in the bottom of the FH. Does this interfere with suppressor mounting? Secondly, what generation of Knights suppressors are compatible with it?
I purchased it primarily for flash hiding capability so if I can't mount a suppressor it's not the end of the world. Just looking at my options.
