As you mentioned CZ will ship you new magazine well, if your willing to spend the money D I P Products sells aluminum replacement mag wells. Its an easy fix to swap out the old to new magazine well, no gunsmith required. I dont care for the plastic nose caps myself, CZ still sells painted aluminum nose caps but it's been ten years since they offered blued steel muzzle caps. The painted aluminum nose caps have an earned reputation for paint flaking/scratching so aren't much of an up grade in my opinion. And there is a company that make aftermarket sights for CZ rifles that offers a taller front sight blade for the rimfire rifles, I'm sorry that I cant remember the companies name at the moment. A web search couldn't hurt, if I remember the name I'll post it later. Good luck
