That's what I was thinking as well, reading through this. You wind up with a heavier unit, and one that may not be interchangeable with existing parts due to modifications needed to be made for structural strength, and I see no benefit in having an AR that is limited to what can and can't be put on it.

and thats the truth. The Polymer lower (and upper) are for the person who is building either a cheaper range gun or a lighter range gun.

I know for a fact a certain high end manufacturer is in R&D on a wire framed polymer lower, or re-enforced polymer lower. The lower could also Sport a one-piece drop in FCG. In the end, this will not be an AR15, only have the general appearance of one.

Are you implying that the S&W M&P Sport receiver is done this way?

I did read what you wrote but what was your purpose of capitalizing, bold facing and underlining the word sport? Why place such emphasis on the word? All I'm saying is you sometimes have a strange way of writing, Fixer. Lots of good info most of the time but occasionally you have a strange way.

I think that we can agree at this point that composit/polymer lowers are simply a novelty. When a sucessful assault rifle design comes around that is intended to be built from polymer it may incorperate some of Eugene Stoners ideas but it will definately NOT be an "AR".

Trying to make an AR from polymers is like P-Diddy trying to re-do "Benny and the Jets". While it may appeal to some. It just wouldnt be the same.

And some people fall into the hype and low price.

I really think that is a lot of it. How many times do we see a new AR owner who just built their first, or is in the process, show up, halfway through it, and THEN start asking questions on what to get?

And since when is seeking a lower cost option a bad thing?
