Questions & Answers
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.

will any of these Mars triggers work with the GSG-16 .22lr. ? Can you answer this question?

This crudely 3D printed lower is painful on the hands and uncomfortable. Honestly feels like it’s going to break in my hands and I don’t even feel comfortable taking it the range. For just a little bit more money, you can go with a reputable manufact...
