RRA Stainless Steel barreled upper

[Zundfolge]

Well since my Kahr sold, I now have the funds for an AR15.

I'm planning on buying a lower and upper separate and putting them together (think I can save a few bucks, plus it should be fun ).

I've found a Stainless Steel barreled Rock River upper and was wondering what the advantage to stainless steel would be (other then coolness).

it sure looks cooler....

you can see my review on my rra here in this forum....

i think the stainless rra are varmint, or nm setups.... 1:8 twist, but don't quote me on that....

the 24" RRA varmint can be had in 1:12" twist. mine seems to prefer either 45 JHP Win and Black Hills 52 MHP. my best group in the 2 outings is a group of 3 in 1/4" @ 100yrds

and the varmints are chambered for the .223 Wylde...
