I built this Walther WA2000. I was originally going to build it in .308, but encountered some problems which made 5.56 a much easier choice. The gun is based around an AR-15 platform. It has an AR Stoner .223 Stainless 5r barrel. Accuracy testing while breaking in the barrel promises sub MOA with handloads.
Here is a spec sheet for an original WA2000
Here is my WA2000 in 5.56 (all SBR's are NFA registered)
The scope is a S&B 2.5-10x, like the original.
I shot these 100 yard groups using PPU Match 5.56. I shot these ten shot groups very quickly...around 1 minute per 10 shot group. Not much wind but the mirage was terrible and I was using an old Nikon 20x scope. So I'm pretty satisfied. I'm pretty confident this gun will shoot below 1moa after break-in and using handloads. I like 10 shot groups because they are a good indication of real world performance. I also shot a .24 moa 3 shot group. Probably a good indicator of accuracy is to take a 10 shot group and throw out the two widest shots as shooter error. I had no problem making head shots on a steel target at 165 yds.
