I only have two CZs. The first is a CZ 550 American in 7x57mm. I refinished the stock in GB Lindspeed Oil, glassbedded the action and first inch and one-half of the barrel, freefloated the rest of the barrel, had the bolt handle polished to a bright nickel color and the bolt body jewelled with a small herringbone pattern, and finished it off with talley rings and a Leupold 4x12x40 scope. The rifle will shoot half inch groups with 162 grain Hornady SSTs and H414 powder. I once shot a three shot group which measured .216 inches. The second is my CZ 527 in .223 Remigton. It began as a Lux, but I bought the aftermarket stock you see on it now and turned it into an American with a 23.6 inch barrel. It wears the CZ rings, a Bushnell Elite 3200 scope in 7x21x40. I glassbedded it and then a gunsmith bud of mine wanted to try to pillar bed it, so he did and it is pillar bedded as well.
