Just a quick note for a small rant.
It really is a shame that the Polish synthetic slab mags don't seem as "tough" as the Bulgarian waffles. 'Tis a shame that the Bulgys aren't as well moulded and finished as the Pole mags.
The Pole mags are head and shoulders above the Bulgarian mags in mould quality, finish, and workmanship. The mould and finish on mine are A+++. Some of my Pole mags had very small cracks around the feed lips, though - some had rust on the springs too.
OTOH, a few of my Bulgys had big chunks of plastic broken off from around the feed lips - the missing plastic was just covered over with that black marker/paint stuff. The grinding of the plastic around the forward catch was haphazard on a few of them too.
Too bad we can't have the best of both worlds.
