They got a bad rap from the cast (cheap as we can make it) plinker model you spoke of. Their other guns are fine. I have 3 of their lowers and one of them is a SGW stop sign marked factory gun. All the upper/lower receivers I have from them are all forged. The factory gun was from at least the 80's I believe, and it had some m16 parts in it like the trigger, disconnector and selector. It has a pin in the side of the receiver to keep you from turning the selector past semi though. I guess 25-30 years ago that was ok. I swapped out those parts with semi parts to cover my ass after the broken gun guy got prison time. My buddy also has two olympics and one is an old billet receiver. I haven't had any issues with mine other than finding out my factory guns A2 profile barrel had 1-14" twist rifling that shot fine with 55gr ammo but would tumble ss109. Not the barrels fault though. I had a DPMS gun that had a cast receiver and I hated it. I sold it and bought the stop sign marked gun. I think the main reason mall ninjas hate them so is that it doesn't have a pony on the side.
