2-MDS PERFORMANCE MDSE04001 .40 FS-1 PRO WITH MUFFLER AIRPLANE -MDSE05800 .58

I honestly don’t know much at all about this. I received it in a storage unit. Everything you see in the pictures goes with it. There is two a 58 FS Pro and 40 FS-1 Pro w/Muffler I believe I only have one muffler. If you have any questions, I will do my best to answer them. Also, I’m assuming these are new but I really don’t know.
