The KWA TK45c Tanker Stock Retainer (Part 508) is an original replacement part for KWA AEG2.5 and AEG3 rifles, listed on TK45c, T6 and T10 diagrams as part 508. It is intended for players and technicians who need the correct component to service or repair the tanker stock assembly without relying on guesswork.
For airsoft rifles that see regular use, small retaining parts matter. Replacing a worn, missing or damaged stock retainer can help keep the rear end of the gun properly assembled, which is especially important on compact builds such as the TK45c where handling and stock stability affect how the rifle feels in tight spaces.
As a genuine KWA airsoft part, this retainer is the right choice when you want proper platform-specific compatibility rather than a universal substitute. If you are already servicing your rifle, it also makes sense to check other KWA internal parts and external replacement parts relevant to your build.
Order the correct KWA Part 508 and keep your TK platform build in working order.
