Will it work on Mac 5 (mp5 clone)??

I got one from l2 prints for my Mac5 but I am sure they are all off of the same file. you have to order for your specific model. mars is supposed to be great. people having issues probably caused them. the receivers are carbon fiber very strong but if you dry fire it off of the gun the hammer will damage the lower. Mars is good but with any super safety you do have to have a bit of understanding and knowledge of what you are doing. it's not hard do a bit of research.
