Badrock, or MPA. They are equal. MPA uses a 3-lug Curtis Axiom action with a plunger ejector and blade extractor. Badrock is fixed ejector, and more like a controlled-round extractor. Also consider a Bighorn Origin build: action for $825, barrel of the Savage style with nut and recoil lug for $550; KRG Bravo stock for $350 (this stock does not require bedding, and is rock solid), and trigger of choice (I'd go with Jewell target trigger with top safety and no bolt release, since Bighorn has side bolt release - check with Bighorn to make sure this is correct) for $220, for a total of $1,950 or so, plus incidentals, such as action transfer fee to your FFL dealer, shipping, and a scope rail. I recommend an extended picatinny scope rail, since most people mount their scope too far back for flexibility in position shooting (especially for sitting or prone). This would at least provide the option for more forward mounting. Of course, if you go that route, you need an action wrench for use inside the bolt raceway, a Savage nut wrench, and barrel vise (Viper without any coating is my choice), along with Go/No-Go gauges for your caliber. But then you're fixed for life.
