They're alright for skirmishing, I have the 09 model, which is essentially the same internals, but all GBBs struggle a bit in low temperatures because of the way they function to propel the BB, as well as the drop in pressure of the surrounding air mass to some extent. The build quality of them is not the best as you have doubtless realised by now, which is only to be expected on a GBB pistol which you can buy new for less than sixty notes, however, It'll do for a while, but you will probably want something a bit better eventually. That said, the mags are okay and can be used with other pistols (since a mag costs about 14 quid anyway), so it's not like it is a completely dead-end investment even when the thing falls to bits, which it may well do eventually if the amount of rattling mine makes is anything to go by; some of the slack tolerances on them make the AK-47 look like it was precision-built by NASA in comparison. :lol:
