metal difference?

[globie31]

I have pretty much decided to get either busy or RRA lower with a bushy upper. I know this is probably a moot question but I remember seeing a comparison chart of the different manufactures that was showing colt and bushy using a stronger metal than the rest of the other manufactures (I can't remember where though). I was wondering how much of a difference there would be between a bushy lower and a RRA lower (durability, longevity, and compatiblity with other parts)? Is that difference in metal worth the extra $80 or so dollars?

The "metal differences" to which you refer were only regarding the type of steel used for barrel manufacture. As long as you get a forged receiver, the quality is going to be about the same between the top three or four companies.

Thanks for the reply, after looking for about an hour I just found where I had had seen the comparisons and sure enough, just as you said only the barrel metal is different. Thanks for your quick reply, that will have me a hundred bucks or so that I can spend on some mags.
