This mount provides a rock-solid Picatinny rail platform, yet is easily removed without tools for cleaning etc. I like this mount a lot, but I ended up never using an optic on my FAL, so it has just sat in my parts drawer for the past year. It has been fitted to my DSA carbine, but should fit any non-para FAL just fine... if, after buying it, you feel it does not fit your rifle well enough, then I will of course give a refund (less shipping). Otherwise, its in very good condition with just the typical brass marks and dings you would expect from a mount with about 100 rounds underneath it.
List price is $135, but you can have this one for only $75 shipped.
