First up, The Barn in QLD is clearing out three CZ 455 rifles that have Boyds Pro Varmint stocks but are fitted with sporter barrels. $699 for just the rifle seems pretty cheap for a new CZ at least.

Then there are a couple of places that are selling CZ 455 rifles with 16.5" threaded barrels (without sights) and hogback stocks. I've seen the one at Horsley Park, but have no idea why it's been priced so high compared to their newer CZ 457 rifles.

I have to wonder if someone threw random barrelled actions and stocks together to do away with out of production CZ 455 stock.
