As for barrels I don't think you can expect what you want for less than $300. Jim Briggs has some chrome moly Shilen barrels for less than $300 Varmint contour 26". Jim sells a Criterion barrel in a light varmint contour at around $320. You'll have to order shorter length barrels as they are not stocked, My build was 24" 6.5 Creedmoor special order. Jim also has factory "take off" barrels, might find something that way.
