Hey everybody. I'm new to AH from Texas. I'm an avid bowhunter and also belong to another forum, Africa is my passion. I've hunted South Africa and Botswana and hopefully I'll be adding Namibia and Zimbabwe soon. I just bought 3 CZ 550's in .375 h&h, .416 rigby, and .458 win mag. I've read a lot about what type of modifications need to be done out of the box and was wondering your opinions on that. I've heard: tune and smooth the actions, glass bed the action and barrel, etc. What do y'all think? I'm also thinking about replacing the front sight with either white or fiberoptic bead any thoughts? Thanks for the help!
