It's simply a more efficient GB system.

Re: what is system 7?

Notable changes include:
- One piece loading nozzles, rather than the metal nozzle insert into a plastic blowback housing.
- Gas blocking valve to stop gas flow to the barrel, like the TM, rather than the floating valve like the WA.
- Reshaped blowback housing, so the blowback now pushes against the barrel, rather than pushing against the mag gas jaw.
- More expencive mags. God knows why. The mags seem to have gotten simpler in design, but they charge more now.
