I've shot both an MP5 and a GSG a few times at HRA/LIFE events. Can't say I'd buy one, since they aren't walnut stocked or WWII era guns, but for faux EBRs, both were a fine guns. Reliable enough, accurate enough. Not something I'd spent $$$ on, but that has less to do with the guns and more to do with my tastes. Now, if they came in walnut furniture, and maybe a lever action variant...
