They are fantastic rifles (actions) that straight out the box are near perfect.
Maybe for daytime stalking/high seat warming.
Dovetail does not allow for easy fitment of picatinny rails, options are either clamp types or the 'glue and screw' approach if you can't wait for a Canadian NEAR rail.
Not sure how much I'd trust the original Sako tapered dovetail with a 1kg+ optic and 34-40mm mounts. This system was the best available when it came on the L46 in 1946, but over 100 years later scopes and optic mounting systems have moved on.
Quality carbon/composite stocks hard to come by. 6+ months wait for a McMillan, which you have to have bedded as well. Easy £6-700 or more.
Aftermarket trigger? Yes, Bix'n Andy make one. Probably £300+ landed.
Magazine system works, but spare mags are expensive. If they are perfect, why do some ask for an AICS replacement? Yet, not commerically available.
Spare factory mags can be sourced, but you are looking at around £100 each.
Factory 'deluxe' models came with floorplates, attractive and functional but not in stainless steel.
All of this added expense for the privilege of having a Sako 75 action.
No thanks!
