If you're under 18, check out FVAA, they play at Bigfoot.
If you're looking for a bullpup, the Tar-21 is amazing, used one but sadly I cannot afford one.
When I started going to games I only had my M4, 2 batteries and 5 midcaps. Now I have Propper Marpat BDU's, hiking boots, vest and a better Pball mask with anti fog!.
Rent first before buying something you'll regret.
