These handguards are like new, only been installed once, then removed. The C4 type is like M4 profile. I can't use them since they interfere with my ARMS #39 rail.
I'd like to trade them for A2 profile coyote brown 20" rifle handguards, in similar condition.
IM me if interested.
I'll put up a picture of my guards soon when it's daylight. I also want to see a picture of yours if possible.
