CZ Custom Shop AO1-LD. One of the best shooting guns you will shoot. Gun is tight with no wiggle or noise. Only reason I'm selling is because I ordered a new one. Gun comes with a Holosun Red Dot, 2 magazines, several grips from VZ and Loc grips. Great competition gun ready to compete. Just got it back from a complete tune up from CZ Custom shop, with receipts.
