I'm hung up on availability of spare parts, so I'm dithering between getting a newer 85 (so that I can buy spares easily) or buy another L579 (so that I can have the spare parts in the form of a spare rifle). But that's not the question and I'll resolve that in time. The question is, why are there so many L579 .243 rifles for sale right now and so few .308? Are the 308 owners keeping theirs and the 243 owners dumping theirs for the 6.5 Creedmoor? Maybe they've burned out their barrels? Other?
