Maybe. Definitely more stable than off-hand. Front pistol grip would probably help too.

If you find a filler block solution you like, I’ll buy your stock especially if it’s an SE / red.
I have had like 5 Vz or cz 58s, and about 3 or 4 t81s
All the t81s had as good build quality and better triggers and less recoil. 58 rifles are known to have more recoil than other similar rifles and it’s true.. though I haven’t held a real AK to compare.
T81 isn’t a better rifle than a 58, I’d say they are equal for various reasons.
