What area of FW? Shoot Smart, all three, have good gunsmithsLooking for good gun shops (particularly Class 3 for NFA stuff) and gunsmiths in town.
Maybe someone will know the name but there is a place off 287 south of downtown. They did a chop job on my Glock and they came highly recommended. One of the guys gave me a tour of the place and they have a lot of CNC machines and can create a ton of stuff. He was telling me about stuff that went way over my head.
