No no no. Post war Czech k98k rifles are nothing like Russian capture k98ks which are complete mixmasters assembled from random used parts stripped from other rifles. The Soviets just assembled them for fit and function and they were not even fired for accuracy tests.
Comparing that to Czech made post war k98ks is night and day. The Czechs used left over WW2 parts to make the rifles, but they followed the same principles as during the war. They had hand fitted metal parts, the stocks were fitted and relieved for proper fit and clearances, tested for accuracy, etc.
The fact that Russian capture rifles still perform decently at the range (for the most part) is just a testament to how good k98k quality control, tolerances and parts uniformity was during the pre-war and wartime period.
Original Post war Czech rifles are just as good in quality and as shooters as any other wartime German rifle, if not better in some circumstances. I have tested this myself at the range.
