Eddie of CRW-Airsoft makes a comparison of two gas blowbacks from GHK Airsoft. Both in stock at his online store, he points at the differences between these two GBB-Rs which can be mistaken for the other. Both are full metal with a Nylon-Fibre handguard and slim plastic pistol grip. Both have folding stock and the AK105 uses external parts made by LCT Airsoft.
