POS Trojan Wall Iland 5.56 pistol. Even after 2 rounds of manufacturer repairs, it doesn't work.

Manufacture has had TWO tries to make these guns work and now one of them (and only one of them) works. Trojan firearms sucks. Their customer service is crap and they don't appear to know how to make firearms. Blames the customer for their crappy guns. First the barrels were machined too small so the gas blocks fell off. Then the buffer tubes were inadequate, then the gun shook the trigger set pins out. They "fixed" those things and one of the guns doesn't cycle.
As an update, I had a real gunsmith go through these guns. They replaced the trigger packs, gal blocks, tubes, buffers, springs...basically they were made of too delicate parts that might have worked in a full-sized AR but in no way were suitable for an AR pistol. The owner of Trojan is a liar and doesn't honor his warranty.
