The money I saved on a ghillie suit, I spent on internal upgrades for my 249 lol
Ohhhh so expensive....
Anyway, be careful with plastic guns, they break when you drop them on cement floors, ask me how i know lol
G&P is honestly the best you can get, not only is it already the highest end metal body, but all you need to upgrade are the nozzle, barrel and hopup rubber lol
Factor that into your costs, If the JG is still cheaper then buy that instead

Of course you don't really need to buy a sniper stock, a USMC SAM-R with a bipod and maybe a scope is all ya need
