General question poly or aluminum lower for the wimpy .556?
I've always wondered if it really matters.

End thread now!
I've read the forged vs. cast arguments too many times.
I have designed repairs for many airplanes and I will tell you that forged only gets a small increase in strength vs. a billet part. Casting has inherent problems that are hard to overcome without a post casting heat treat/stress relief process.
The most important thing for strength, as far as aluminum is concerned, its the composition of the material. 6061-T6 is the crap hole of aluminum material. 7075-T6 is freaking awesome- literally double the yield strength of the 6061 stuff. The "T-number" after the first four digits refers to the heat treat of the material. -O "plain" is the worst. -T43/-T6/-T63 all vary in their properties as far as the material is concerned.

That's the reason I've never gone with poly.A .556MM rifle would be very wimpy indeed...if it existed.
Or were you talking about a .556 inch caliber beast? Probably not a wimp at all!
For 5.56MM rifles, I prefer the strength of metal to prevent wear and slop at the pin holes.
Not really. The one's I've seen are actually more $$$Are poly lowers even cheaper? If they are by how much?
