9-10/20 surplus FN FAL 7.62 Nato metric magazine. A Magblock 10 round limiter has been installed and a 1/8" rivet has been inserted into the floorplate and limiter. Poor to fair surplus condition, may be coated in rust, dings, finish wear, and dirt. However, the mags should be fully functional and are most certainly "preban". Some of the blocked mags only hold 9 rounds or the tenth round may be a tight squeeze.
