I've been to Avim near the Florenc metro stop multiple times, it's mainly a pistol range but you can rent an AR-15 chambered to 9mm and a shotgun, not been for ages now though. Last time I went it was about 1000Kc (~£30) for gun rental and 100 rounds. It's not really good for big groups either, 4 is about the maximum.Anyone done shooting in Prague and can recommend one in particular to go to?
