Riflechair has a vid out where he tightens up his SKS groups with a bit of bedding..
So $1000 bent 81 or.... 4 SKS's and some bedding and get some accuarcy out of a good solid , proven reliable platform
Except.....Nobody bought a Type 81 to shoot groups with! It's for whacking gongs at moderate ranges, shooting beer cans in the bush and looking very communist!
