9/22/16 All of the pics are gone due to a photobucket problem a few weeks ago. But new pics are in post #209
I'd like to personally thank Noodles' bundle of pessimism for giving me the motivation to make this possible.
Post #54 has my build progress so far. Much of this OP is irrelevant now but lots of good info from SMEs and pros in the responses.
I've got a lower begging for an SPR build. I would like to shoot 4" steel hangers at 600 yards with it. I previously had a Noveske upper in 300BLK that was a tack driver and great for hunting but that round will not reach 600 yards.
Questions:
What barrel length should I go for? This will be shot suppressed. I am fairly set on 18" as it will provide a boost in velocity without being too long, but I will consider 16" or 20" if someone can provide quantitative and qualitative reasons for doing so.
On that note, what upper should I buy? I'm really liking the BCM 18" with KMR-A 15" price point. It's like $800 delivered with a rail panel for my Atlas.
What load (I reload) or factory ammo should I be shooting to do what I'm trying to do? I have no experience with precision 5.56mm.
My lower has a carbine RE. I'd prefer not to remove it and get an A5 but I will if necessary. Can a carbine RE work with an 18" barrel? What buffer would I need?
I have an 2-8x Vortex already mounted in a Bobro from a previous build. I've shot to 600 yards fairly well with a 4x ACOG but never at 4" hangers. I plan on upgrading the scope eventually as I know it isn't ideal, but will the 8x be a waste of my time or can I get away with it for now? $1000 for an upper is a lot easier to swallow than $2500 for an optic and upper.
