@JVacation if i had to sort out a starter to get into Airsoft, I would do the following
JG G36 https://www.surplusstore.co.uk/bb-guns/realistic-bb-rifles/by-model/g36-variants.html?product_list_order=price_asc
£140
I would spend another £50 or so and get it into a gun tech for a gearbox look over, reshim, regrease, change to deans and change the hop rubber to a maple leaf.
Then, bar ammo, batteries and eye pro. You have everything you need to get going.
470 round mag and a solid, reliable AEG, that would be on par with the highest gucci guns on the field.
There is a reason that most sites run G36's as hire guns. They just work. Robust, good gearbox and rotary hop.
