Of your list, I have KAC SR15 , LMT @ Noveke
First question is are you looking for a hard use type AR that you are going to shoot the ever living crap out of ( ie you want a CHF barrel ) ? , or are you looking for something to shoot hard but want to put tiny holes in paper
Hard Use ARs
As some one already mentioned, the KAC SR15 is the height of AR-15 design . The reason is the E3 bolt . Lots of information out there so I won't bore everyone with details. Do not get hung up on the proprietary design . Not going to get into a internet argument on people who disagree with this ...all I will say is if you understand the advantages of E3 bolt over the conventional you would not give it a second though
Nothing extraordinary with a Colt , with the exception of the much vaulted Dimeco ( Colt Canada ) CHF barrels. The KAC SR15 has the same barrel
Other hard use choices that are on your list is the Noveske N4 barrel guns . The pictures above are N4 and SR15. I bought both to see which I would like better and sell one... but ended up with both ! The N4 barrel is a FN made to M249 spec ( machine gun barrel with heavier chrome lining )
Most of these style Noveskes are built on Vltor VIS monolithic upper
If you want a conventional style upper, I would go with one of the two above . If you want a quick change barrel ( makes caliber conversion much easier ) the LMT MRP is the way to go ( available with piston or DI ) is awesome.
Chrome lined Barrels are made my Rock Creek ...claim to fame is they are overbored before CL so no need for etching after. Supposedly more accurate. I haven't notice that though
Conclusion : if you want this type of AR, then buy a KAC SR15 ( ambi lower may or may not be of interest ) . Not because I'm a KAC fan, but the E3 bolt is huge design improvement over conventional. A close second would be Noveske N4
If you want quick change then LMT MRP
Stainless Match Type Barrels
I have built on Noveske stainless , Krieger, Shilen ( from Rainier arms ) , WOA , Satern and others
I can say that the Noveske stainless barrels are simply outstanding . They are Pac Nor blanks ( steel spec by Noveske turned by Pac Nor) made on Pac Nor button rifling equipment
If find that for AR use, this is as good as the single point cut rifle barrels from Satern / Kreiger
Anyone who says 14.5 " , 10.5" etc cannot be as accurate has not shot a rifle with a short Noveske stainless barrel.
So, from your list, if you want an stupid accurate gun, then go for a Noveske with a 16" length. The SPR length / profile is relatively heavy ( a brick compared to KAC SR15 or Noveske N4 ) and you won't miss the velocity
