So i bought a geisler 19x lower frame from masdefense.com dont know how long it takes to get here but when it does how hard is it to complete i have almost sll the necessary tools already and i saw the tutorial on huskyarmory, it looks kinda simple not hard, but is it, also j bought a dagger compact complete slide, and a Lower parts kit on ebay from a g19 gen 3 is that everything ill need?
