To improve the trigger, you just need the Brook's kit. But while you are at it take a look at the action screws offered by Brookie. If you are going to shoot iron (open) sights, you should try one of his "Ghost rings". If, at some time in the future, you decide to scope your trainer, you can add his adapters and Burris rings. No, I don't work for Brookie, and I didn't stay at a Holiday Inn last night. He just offers good products to enhance the CZ 452's.gump said:ok do i just need the brooks kit or something else?
