Are we talking the 5.7 X 28 uppers for AR's that utilize the P-90 magazines?

An expensive addition in an inferior caliber that is difficult to find and even more difficult to reload fed by expensive, albeit cool magazines.. I'll pass.

If I happened to have a few cases of ammo and a dozen magazines given to me, I might reconsider.

What's wrong with a standard A2 or A4 upper? Why the interest in all of these difficult uppers?

Thanks for the input. I know it is an inferior round, I just had the chance to pick one up for real cheap. But the ammo price and the fact that it is hard to find greatly out ways the price I could have got the upper for.
Thanks again. You guys are a wealth of information.

You would prefer me to pick up where you left off and run the suggestion the rest of the way into the ground?
