Welcome! Airsoft is built on honesty so make it fun for everyone and take your hits, go home with a clear conscience 😎
Bang for buck the SA E03 or Arcturus GR16 IMO.
As for G&G I like them but you’d want an Advanced series and they cost more.
I would not advise anyone to buy Ares, they are special in wrong ways.
I wouldn’t get to bent up on a DMR, if your assault rifle is tuned there’s not massive difference in range between them.
To make a truly worthy DMR you’d want a specific rifle that wouldn’t work in other roles really.
