Today I took my new SCAR16s to the range and found out that my 10 new AR military mags will not work in the rifle. The bolt misses every second cartridge and I have to manually work the bolt to get a round in the chamber. The FN mag works just fine. I cannot see any difference between the FN mag and the AR mags. It doesn't make much sense for this rifle not to be able to use AR or M16 mags. I am sure the Special Forces don't just use FN mags. That would be really stupid. Can anyone tell me what to do to make these mags work? My p mags work fine and they have been modified to avoid the bolt hitting. The AR mags are open the same as the FN mags. Confused and concerned!!
