What does the leading French airsoft reviewer, L'antre Du Dingo, has to say about the Umarex/VFC PSG-1 Gas Blowback Rifle? Probably lots, since the video is over 30 minutes. The Umarex/VFC PSG-1 GBBR is the first gas blowback version of the PSG-1 rifle made by Heckler & Koch, following over a decade of introduction of the first PSG-1 AEG from Tokyo Marui which became one of the favourite electric airsoft sniper rifles during the naughts of this century.
