I seem to recal having heard/read that cast receivers for the AR were crap and/or potentially hazardous. Any comments?

They are weaker...

They are more likely to crack under pressure (literally) but I've never seen or heard of it actually happening. The lower doesn't get put under that much stress unless you're using it to buttstroke people and/or jumping out of planes with it.

Thanks for the input, guys. I would never own one, but a buddy of mine just bought an AR w/ a cast receiver which I thought was a very bad move. I just didn't know if they were so bad that he could expect a catastrophic failure...

I've seen rifles built on cast lowers that are over twenty-years-old and still going strong. These are regularly used rifles - not safe queens. For typical use, I don't see a problem with them. That said, when forged lowers are available for only eighty bucks - there's really no reason to buy anything else.

I have 4 ARs. 3 with forged receivers and 1 that is cast. The cast one is a DPMS and I have an OLY 9mm upper on it that is fired several times a week. It is a range gun and has held up well with me banging it around. No ill effect for the past 2 years. That being said for heavy duty application I would trust the forge receiver more.

I agree with what some have said here.... the cast receivers are less durable in the long run vs. forged receivers, however thats not to say a cast receiver isn't any good or prone to catstrophic failures.
I personally have a preference for forged receivers and only use 7075 T6 forgings for SNS MAX-15 receivers.
