£200 will get you:
Zero one 2 tone 4 free
G&G Raider or CM18 - £123 to £155
or
Airsoftworld.net limited edition G&G GC16 mod0 £150
(not 26 model IMHO front sight is crap)
2 tone extra but all metal receiver
all G&G's will be fine but raider cm18 or GC16 mod0 are great for money. About £40 to £60 change for battery charger n a spare mag
GET DECENT EYE PROTECTION !!
even carbine at about £117 is a good one but pay a little extra for Raider or sexy CM18
and you got loads of rails to mount all your crap on later
There are other makes but most on here will suggest G&G as a very wise investment
decent, look good, build quality is good, easy to work on, hold their money compared to some crap out there
very good starter - intermediate M4 guns out of the box
buy other cheaper stuff and you will probably/very likely regret it
Edit - my warning came too late as you got a D4817 already
(no worries I bought crap too first time around - B500A1 $hite)
