All I can say is that the Krieger will out shoot many NM barrels because of the time, energy, and sweat put into the manufacturing process. You truly will receive what you pay for. Kriegers have a reputation for accuracy, consistency, stress relief, lapping, smoothness, and all the characteristics common to a superb barrel.
At least once before I leave this planet (read: I'm not going to live forever like Elvis) I would like to own a Krieger barrel on any of my M700 or M14's. All I have experienced are Douglas NM Heavy barrels on many of my M14's and they shot into dime sized groups at both 100m and 200m, just ask Skullboy. I built one for him back in 1993 and he showed me centerpunched .38 Spl cases shot at 200m.
Hmmmmm maybe I smell an idea ... It might be time , when I can no longer carry out the rundowns in Service Rifle (I've already got 2 hip replacements) to build up a Norinco M14 with a Krieger JUST to shoot iron sighted Target Rifle class. I can dig up an NRA shooting jacket, just like when I started out back in 1985 with NRA High Power.
Peace out!
