I get them from my local retailer
Airsoft Gear
Loved BBBastards but IMO I'm indifferent and get whatever high quality brand I can get my hands on. That includes Green Devils (used these while I was in the UK), Madbull, BBBastard, Excel, Airsoft Elite, Metal Techs/MTMFG, etc. and I've been approached to test out a new brand of BB's which I will do a diligent and through review on.
