hi buy the best you can afford simple, any semi is not going to be acurate the act of it cycling another round see's to that and any one who tells you they are as accurate as a bolt is full of what makes the garden grow, i read all the time people who say CZ's are crap because of their triggers BOLLOCKS and you dont have to buy a new trigger unit to make it shoot, if you have a reasonable amount of sence you can do the standard trigger your self, quick lesson knock out the pins put the blade to one side take the trigger spring and grind of 4 coils this alone takes the trigger from nearly 4 lb
