The longest you can find is 510mm - Tanio Koba twist (effectiveness limited to 1J of power. Otherwise, it's just 500mm for a standard tightbore.) The only aftermarket barrels that fit the M14 is 510mm, 500mm, and SOCOM length.

2) No bore up kits exist for the TM M14. Good luck pushing more air through a cylinder designed for 500mm. I have no idea if it will work or not (but I have a feeling you can max out at 600mm.)

3) You can replace the entire outer barrel, but you'd have to have it machined from the bottom out. It'd be easier to just get a barrel extension. Lots are available. Look towards Guarder.

This isn't a project even I would attempt. The M14, although a great gun, is not the best platform to start out with, unless you have a lot of time, patience, resources, and CASH.

Would the barrel extensions act as an inner barrel (In terms of increasing the gun's range)?
