If your worried about the twist rate, the Krinkov's with the original barrels never achieved the accuracy the Soviets desired. The designers tried to fix the problem by increasing the rifling twist rate. They continued to not meet the desired level of accuracy but that was the best they could do and they left it at that.

Short barrels with rifle cartridges have a couple of problems. One is stabilizing the long (for caliber) rifle bullets and another is the muzzle blast and unburnt powder caused by the large amount of powder and slow speed of the rifle powder. Even increasing the rifling twist rate may not have increased the accuracy of the short barrel with the 5.45x39 cartridge but the fast twist rate remained as part of the Krinkov design as maybe to help stabilize the bullets and maybe aiding accuracy. I think the Romanians tried a faster rifling twist rate in their full size 5.45 AK's as an accuracy enhancement. The British didn't like the accuracy of the FAL rifle compared to their Enfield rifles. The British changed the FAL rifling from 4 grooves to 6 grooves in an effort o improve accuracy. It didn't change the accuracy of the FAL rifles but the British left the 6 groove barrels in their L1A1 design of the FAL rifle.

In other words if you want to build a krink and only have a 16 inch barrel, it make no difference with the twist rate. Cut the barrel to the length you need.

maybe subconsciously

I was just on that site right as you posted. What do you think about throwing one on a NDS?

I don't reload (yet), and I don't know if you do, but do you think it would be possible to hand load some more accurate loads by maybe using a faster burning powder and less of it?

The current FPS for the 5.45x39 mm muzzle volocity runs in the 3000 - 3100 FPS. If you could slow the round down to 1800- 2000 FPS in the Krink your accuracy would improve. Think of your krink as a pistol.
