Please Note: On most PTR rifles and HK91 clones, these mags may require fitting on the mag catch area for lockup. You need to file the mag catch area slightly to fit your firearm. For example, most PTR firearms have a mag catch placed higher than a factory HK91/G3 rifle, so the mag catch hits the top of the raised area and does not lock in properly. A few careful strokes with a small file on the top of the mag catch area, and they fit as they should.
