Buy a Mountain LSS. Buy a Ti stock. Find a stray ADL in your safe or buy an awful one. Swap the Ti stock onto the Mountain LSS, and the ADL bottom metal. Sell laminate stock. Grab a dremel and convert your old ADL into a BDL (or just score a crappy BDL takeoff stock.) Sell or keep the new BDL rifle. Sell the original ADL stock if you bought a new BDL stock. Resist the urge to put on a new barrel, trigger, mcmillan, or other upgradey junk, lest you render this a lesson in being overbudget.

Instant "special run". Should net out to similar costs, minus your time. But you get a better chance of having the caliber you want.

(I have one of the Cabela's versions in .308. Also purchased on clearance, for 509, iirc.)
