Yawn! Not another M4 but based on the drawings we received from Modify-Tech, this will be different. If you look at the Modify (Xtreme Tactical Carbine) XTC closely you will see that the receiver is re-designed, with a new grip; a the new ambi fire selector that goes MP5 style (meaning the lever only travels 45degrees instead of 180); new steel trigger; and LED in the HiCap mags so no need for separate tracer unit, rotary HopUp chamber.

All this packed into a single gun and we did not even talk about the gearbox.......the gearbox we don't know too much about only that it is 'revolutionary'. So far we couldn't get on a high resolution rendering of the gearbox itself, and the only thing (apart from the file selector gears) is what we can see from the outside is that the back of the gearbox is completely missing, I am only guessing that's where the WITCHCRAFT will be loaded into the gearbox. I can say one thing what is not on the drawing: the right side fire selector will be half length. It looks like we will have to wait until IWA.
