We just recently found out that these M4 (CM16) GBBs from G&G are available at Pro Airsoft Supplies in London... "We've been testing the hell out of them since Monday and have been really impressed. G&G's gas blow back guns represent huge improvement on similar efforts by other manufacturers. With the standard carbine starting at only £149 and the limited edition Raiders, with full metal rails and a flexible stock, rather than the standard crane stocks, starting at only £169 pounds! This is the first and only batch in The U.K. that we are aware of and we only have a very limited stock. If you want one then you'd better grab it quick! These GBB's from G&G really do represent a huge leap forward in terms of affordability and reliability of gas blow back guns!

Find them here.

We also have more of the G&G UMGs in! As you may have seen in the latest edition of Airsoft International, the G&G UMG's 'Performance is frankly ridiculous! ...Rock solid construction, excellent ergonomics, reassuring reliability, consistent accuracy' - try one in store today!"

If you want to drop by and give the shop a look and their stuff inside, they made a shop tour video:
