Hey guys, I got 2 TM MP5s - one was given to me because it was upgraded to 350+ fps but something went wrong in the gear box and the gun is busted. I pulled out my stock internals from my old one, and trying to put it in the broke one. What other parts should I consider swapping to get a little bit better range and fps?
Also, I got a longer barrel from another gun and far as I can tell it can be swapped into the MP5 if I bore out the flash suppressor a little bit. Are there any consequences for doing such a swap?
The gaskets and seals also look interchangeable. Is there something Im missing?
