Bit late to the party but I remember those days of first AEG, back in 2015 raiders were the choice then as well, I did however go for an ICS UK1R, still use it today, but played once since 2019 ??♂️
My 14 yr old has played a game, due to age restrictions, couldn’t go sooner, and loved it, luckily though I’ve amassed a small armoury and wardrobe collection he is almost set but I feel your pain of duplicating most equipment ?, I’ve kind of all gone M4 base with the AEGs, even the G36 (ICS G33), takes M4 mags so atleast he can use my hi-caps ?
just make sure he enjoys it, one thing I would recommend is radios for you both, my worst fear was the ‘cease fire’ call and man down!, I was the only one moving looking for him with that parent fear something had happened to him….found him with another youngster and loads of big kids preparing to storm a building having the time of him life ????♂️
hence radios…!
