Got my order placed for a CZ457 Pro Varmint after I was finally able to find one in stock without paying an arm and a leg What is everyone's recommended upgrades to start with? I already picked up a 20 MOA Area 419 rail and will be topping it with a Diamondback Tactical 4-16x as I figure that is more then enough for 50 yards will it will primarily live but yet still allow me to stretch it out a bit if I want to challenge myself. Are there any other upgrades I should consider right off the bat?
