You can certainly build a rifle cheaper than this, but here's my current build for reference.

Savage 11 in 7mm-08 because I couldn't find an action $435 + shipping + ffl transfer

Barrel - $300

Trigger $85 - wouldn't be needed with an accutrigger

Stock - $100-$700 depending on use

Tools - Action wrench/Barrel nut wrench/headspace gages/ $130

It definitely costs more but you get what you want instead of what someone thinks will sell.
