Upgrade on a G&P M4 CQB

[rtf1976]

Thinking of spending a little cash and time on my main AEG (Recently been re-shimmed and new anti reversal latch)

Was thinking of a tightbore and new hop unit

Any suggestions on makes for above

Barrel length is currently 275mm and dont want to extend it

Anything else should consider upgrading?

Cheers

If it has the G&P M120 motor then i'd get a mosfet for it. Also for hop unit the Prommy neo chamber, Systema or Madbull Ultimate. Barrel wise you can't go wrong with a Prommy or Madbull.

Closest I can find is a Madbull Black Python Ver2 6.03mm but is 285mm
