Classic Army SLR-105 A1 barrel
 

Hi! I want to upgrade my barrel to a tightbore. But the barrel is 463mm (not 100% sure) which is pretty rare and expensIve. Will a 455mm fit to my Classic army SLR-105 A1?? Thanks!

It's only 8mm so it won't affect anything for being shorter. Most AKs use the 455mm long barrel so there shouldn't be any issues.
Quick tip: if the end of the inner barrel rattle/move around within the outer barrel, wrap a bit of tape around the end so it's snug. This will help with consistency.
