That Gunbroker search must have taken a while. Don't you have a job ? or a life ?
As a completed item search, it took about 5, maybe 10 seconds.
This is where your fuzzy math comes into play
Nice rifle. $751 plus shipping plus FFL transfer, plus $400 Shilen bbl, plus fitting, plus chambering, plus SAKO extractor, plus trigger job and where would you be at ?
Best guess +-$1500.
your valuation is taking into account a completed NIB rifle, that is a limited edition, and adding a aftermarket barrel.
You also are puffing yours up as a former DGR rifle, which it no longer is, to increase the value?
You have a used action(375 ish), with factory tupperware, and a used after market barrel (400
new and chambered according to shilens website). A trigger job of unknown etyology and a sako extractor ($30-$40) installed by who? and how long ago?
And that some how equals a grand....
what's your round count that justifies the accuracy guarantee?
