Airsof Atlanta –

Get the Airsoft of the gun you carry or the gun you own or train with. Get the green gas (propane) though extreme weather (cold or heat) effect them they are best in my oppinon.
I own 4 KWA G19s, 2 KWA G23s, an AR15 and a AK47. They run a little over a $100 for the pistols and & $200 for the rifles, but a great way to train in your garage or do FonF with friends or training partners. Mine usury last a year of hard work before they need to be replaced.
