Bought this way back when from Redwolf airsoft when Redwolf use to offer Airsoft surgeon custom guns (think he still do). This is a tier 2 conversion of TM Hi Capa by airsoft surgeon with airsoft surgeon slide, outer barrel, recoil spring plug, adjustable trigger, uprated springs and hop rubber + I've installed a magwell and a extended slide catch. Well put together gun and shoots flawless. I paid around £270'ish for it, looking for £150 including both post and paypal. PM if you have any questions. UK mainland only sale, or posting to Ireland or EU at buyers risk.
