Get the stripped lower and the Wylde. The Wylde will shot both 223 and 556. It can handle the higher 556 pressure and better accuracy when you use 223. It's the best of both worlds in a hybrid barrel.Ok need some advice. Susan and I are going to the NRA benefit dinner with the Pink Pistols. As part of our "Donation" we each get Complete .223 Wylde or 5.56 parts kits in either rifle or pistol configuration plus stripped lowers or 80% lowers plus router jig. I am thinking the Wylde is a better option my question mostly is get the ready to assemble lower or go with the 80%? Thanks!
