I also really like the look of the mil-spec A2 front sight and it's retro styling. I will one day build a 14.5" mid-length upper with that configuration. I enjoyed my norc with that size barrel and sight and want to get back to something like that again (someday). Right now I'm building a 204 Ruger upper, then I want to build a 458 Socom upper, 300 Blk upper, 18" SPR upper, and then finally a 14.5" mid-length upper to round out the collection (for now).
That's my story anyway (I digress).
