WTS: used YHM Lightweight FF (carbine length): SOLD to Brushdog in less than a half hour!
$50 shipped via MO, or Paypal. I had this mounted for less than a year on my Bushmaster. As far as I know, there is nothing wrong with it, I just wanted to upgrade to a Larue. If I find out that this is too high, I'll be willing to lower the price.
Please note, there are a few minor scratches from install and removal on the ring. There is also a few scratches on one of the rails from an Eotech rubbing it.
