Please note: That 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 to your firearm. For example: Most PTR firearms have a mag catch that is 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 stokes with a small file on the top of the mag catch area and they fit as they should.
