Geonox Airsoft shows the BTG Custom F20 as the best entry level airsoft gun you can get for €220.00... "In this video we look at the BTG Custom F20. It is an AEG. It is battery-operated, has 0.5 joules, can be played on a game day from age 14 and has semi-auto and full-auto. The highlights include the double-sided fire selector lever, ETU and Mosfet and the shortstroke on the sector gear. Many thanks to BattleTacGear for providing me with the airsoft.
