Hiya Turner83 and thx for your thread. And seeing its your first post would like to welcome you to the forum from phoenix,arizona.
I really don't know what your hand guard is for ,or what type of build you requested from the ATF. Is it some type of CZ ? Perhaps a few pics may help operators with the jist of the project. Sounds like you've seen a pic of what you want and its a factory part,if per chance its a model of CZ, a toll free call to cz-usa and ask for the extension to parts dept. should be able to answer your questions.
Do let whoever is doing your barrel work see the dimensions you included on your form so the build conforms to what you recorded to the ATF, save a headache down the road. Be well.
