Panzer M4 Speed Pro thread

S&J mag tube extension is no go

Will be returning it.
The threaded position is in a completely different spot.
So like mentioned in other threads. The mag tube would need to be changed to accept it.

On another note. Not a fault of the gun imo n the nut on the front sight did back off
Another 100-125 rounds or so yesterday. Ran and cycled fine. All target loads. Some of wich were 1180fps
