I bought a MK19 kit with the idea I would do a semi or post sample DD, I finally got my own FFL 07 and will be paying SOT next year in Jun., but I didn't acquire any plans for it before hand. I know..I know, I am still working on my M60 and I have a M2HB kit sitting in the shop as well, why the hell would I buy another kit? I think it is a mania or something. I want to open the door to my safe room and see my old USMC armory. Anyway, any of you guys or gals ever hear of a semi DD MK19? I have seen a few builds on post-samples but I believe mfg. of DD is required for that build. I am looking for plans and info on either or both. Any help is greatly appreciated and I promise to finish the build thread on the M60 soon, the secondary trigger pack is kicking my ass.
