Build a Gun? or Buy a Gun

[emrich-55]

I have a Sako Finnlight 270WSM. I have been packing it around the mountains for close to 10 years. Its is getting pretty beat up.

Question is:
Do I build a gun using the Sako Action? So new light weight Stock and Carbon barrel.
OR
Do I sell the gun and just buy a Christensen Ridgeline Titanium?

Thanks
