B4A1 Decision help!! pls asap

[Matt 476 0]

I have a weird situation and need some quick advice. Heres the back story,

I'm 18 and have wanted to play airsoft for so long but my parents are very anti shooting plastic bbs because reasons I don't think they don't even know. They just are. I recently found a Bolt B4A1 REG. It seems like the perfect gun slightly used all metal has some recoil and it comes with 6 mags all for 250 $. Sadly 😞 my parents are still adamant about not shooting my friends because Ill probably become a mass murder or something. As if I haven't played nerf for like my whole life! but whatever I guess an m4 looks scarier!!

The thing I need help with is, If I can, should I but the gun and just plink with it until I move out or something?  I like the gun, its an ERG and the owner has set it aside until tomorrow for me.

Any advise would be really helpful!!!

thankyou,

Matt
