SSD:
How do you do & how'd you do?
Congratulations on your purchase! You've got a rifle!
1.You got a .308 Remington, so I'd say you did fine. That's a good choice in the caliber and will fit the portable gun spot pretty well. For a 1st bolt-action, you done good.
2. Changing it to a BDL floorplate style or a DM can be cost prohibitive. New stock, kit, work, time down, etc.
There are kits to change it, I can't remember the name of one in particular right now, but, it still involves a lot of the above mentioned work.
Don't do it now. Get to shooting it for what it is, a blind magazine ADL in .308.
3. You could get the Harris bipod and some Butler Creek flip-up lens covers for the scope. And a sling.
Most of all, get a lot of ammo and practice with your new acquisition.
You think the wife is pissed now, start changing everything on the rifle and show her those receipts...
Don't do it!
I'm still going to have to wait on getting mine, and the final configuration is not etched in stone yet. I'm really wrestling with the ideas, so I'll be ready when the time comes.
Good Luck on yours.
You've got it in your hands.
(you might want to sweet talk the wife a bit for awhile...)
