Lantac slide for gen 4 Glock 19

Complete Lantac Razorback slide. Barrel is ported. And I have both a Gen 3 spring with adapter, And a Gen 4 spring that will go with it. Firing pin assembly is from Zev tech. Ameriglo sights, These will cowitness with a red dot mounted. At least they did with my RMR that I had on it. Cash is preferred. Thanks
