I first went skirmishing in April 2014 at Dragons Lair using a rental gun with 3000 G&G BBs and then decided to get an AEG around August 2014, the gun i was after was an M14 EBR (short barrel) rifle, i didnt have UKARA at the time so i looked hi and low and found the AEG i was after from JBBG, called them and explained that although i didnt have UKARA i did have another means of defence for which they were happy to accept so off i went and got in it person.
Upon arrival i noticed two distinct things, they had a very small section of decent quality G&G guns being sold at their standard MRSP and then a large stock of two tone trash, thats not to say all two tone guns are trash (see G&G CM) but these were genuine chinasoft trash being sold at a marked up price.
Whilst the guy behind the counter was friendly enough and didn't push me to buy anything i didn't want there was an air of "this is a bit dodgy this shop", anyways i bought my gun whilst a 12 year old boy of the travelling community was deciding which pistol to buy with his pocket money with his older sister acting as his over 18 adult. They also gave me 5k worth of Bulldog BBs which may i add is probably the worst BBs i had ever seen, they looked like sheep poo compared to the G&G stuff i got for free at Dragons Lair.
Since then i learned that any airsoft shop with the word "BB" in their company name is likely to be crap, not to buy from JBBG for decent skirmishable stuff and stick to reputable Airsoft shops like
Zeroin (well sometimes reputable)
Landwarrior (bit pricy at times)
ProAirsoftSupplies (never has anything in stock)
RedWolf Airsoft (very pricey, lean too much on their Hong Kong counter parts name and youtube)
Wolf Armouries (good shop and prices, s**t website)
eHobbyAsia (great prices and lots of stuff you often cant find, long shipping which can be costly)
Evike (lots of stuff at US prices but watch out for customs)
Airsoft Zone in Romford (great prices, shop and staff, dont know how much their P&P as i go in person)
