i have a couple Sako’s in 264. Mine have 26” barrels. Are these rare? I mostly see 264’s with 24” barrels. I assume the earlier rifles had a 26”, then they went with a 24. Why would they do that? One has a white line spacer. Is that factory or was it added?? The rifle with no spacer has a 3 digit serial, rifle with spacer is around 2200. Thanks for replies!!
