whats your best Airsoft venues in dublin.

The answers to this will be extremely subjective and probably useless.

Personally I like to bring my G36 out to HRTA and Redbarn.

HRTA doesn't look like much it sure does a bunch of stuff in a field really really well and plays host to a lot of more milsim oriented gameplay.

Redbarn is a very good site for the Saturday or Sunday skirmish with some nice woods to play in and a very good sandbagged abandoned farmyard with a cool WWII sort of vibe to it. I haven't been out there since they expanded (well, once, but there weren't enough there for a game) but I'm sure they've kept up the good work.

You should consider going further afield as well, I can recommend ABZ in Portlaoise for a day trip (the facilities are poor but the site and games are excellent) and though I have yet to get a chance to play there I hear good things about MAC.

Somewhat more controversial I have to say would be the sites I disliked when I played there. I found Fingal to have a very poor location, prone to waterlogging and excess mud (when I visited it was a raining and much of the lower part of the site was a quagmire). The site itself also lacked for facilities when I attended having not even somewhere to get out of the rain in the safe zone, the best facility being the shop next door which you should patronise if you ever go there. In the end the games did not make up for the sites poor quality though it might be better in the dry after a long spell of dry weather.
