Yes, you can make that happen. It likely won't be cheap.
What you might want to do is to step back a step or two and ask yourself seriously just what real purpose would your achieving reliable 1/4MOA accuracy serve, and whether 1/2MOA might not be a more reasonable goal that puts that same smile on your face. Bear in mind that this is a Tactical site, not a Benchrest site. Some forget. Nothing against Benchrest.
I haven't dealt with Northland, but what I read here leads me to trust their abilities. I also (especially) like Savage rifles, but some don't, and there are better rifles out there.
Handloading is a must. For 100yd, 50-53gr flat based bullets are very good, and Varget is a very versatile powder for 223 (I use 26.0gr under the 50-55's). For out to 600yd, one can go with heavier bullets. I like the basic stuff and my 600yd bullet is the Hornady 75gr HPBT-Match atop 23.5-23.7gr of Varget. Starline brass and CCI BR-4 (only if head to head tests show significant improvement over CCI-400). A barrel with a 1:8" twist works, I prefer a 24" bull barrel.
BTW, AR's can also deliver 1/2MOA reliably, not especially easily, just like bolt rifles. Good barrel, good trigger; you may even save some money, too.
The
Stag 15 Varminter Kit is affordable (you will still need to buy a stripped Lower). If your Lower has a good trigger, try just the
Upper.
Yes; they're out of stock right now, along with most of what Stag makes just this moment. They're in the process of moving their operation; lock, stock, and barrels, out of CT right now. Smart folks, Stag. Check back with them in a few months.
