has anyone purchased one of ghillie's mp5k kits or one of the subcal complete units ? i have emailed with questions ; extra parts available ? extra mags ? capacity ? reliability , etc . with no answers. i am interested in one that will run in f/a and run well. iv'e had one of flemming's older conversions for m10 that never worked well . can anyone give a range report on this unit ? i've been interested in buying one but when you can't get a reply you wonder. as posted i have one of the hk g3 units for my 51 that eats !! if the mp5k does the same i'm interested. if you bought the kit waht all was involved in putting it together to make it function perfectly ?
