well Ori'ad... I know that the Beretta Storm is not actually collapsible! lol but... I do know that there are no Airsoft copies of that particular barrett... and yeah I know the MSRP on that thing is outrageous. I know that they have the M82A1 which is the slightly larger, box mag fed version on a few websites like Airsoftgi.com and Airsoftglobal.com. However, they are somewhat expensive as well, I have seen some versions that are as cheap as $1K and some as expensive as the real steel head thumpers. OpsGear Tactical has a nice upgrade kit for paintball markers that strongly resembles the Barrett 82A1, I don't recall the actual price of that kit but it wasn't much and if all u want is the look, then it might be worthwhile.
