• Genuine Feinwerkbau factory filling adaptor — part number 1877.001.2
• Compatible with all Feinwerkbau compressed air (PCP) rifles and pistols
• Short-thread design — for 300 bar bottles a separate thread adaptor is required
• Not suitable for CO2 cylinders — compressed air use only
• Ensures correct fit and reliable seal when charging from an air bottle or cylinder
• OEM replacement part — maintains the integrity of the original charging system
• Sensible spare for any competitive or club shooter running FWB equipment

The Feinwerkbau 1877.001.2 is the genuine factory filling adaptor designed for use with all Feinwerkbau compressed air rifles and pistols. When your FWB pre-charged pneumatic needs topping up from a charging cylinder or air bottle, this adaptor is the correct interface between the gun and your air source. It features a short thread, so shooters using 300 bar bottles will require a separate thread adaptor — this part is intended for standard compressed air filling only and is not suitable for CO2 cylinders. As a genuine Feinwerkbau replacement part, it ensures the correct fit and seal every time, without the risk of cross-threading or pressure loss that can come with generic alternatives. Keeping a spare on hand is good practice for any serious target shooter running FWB equipment, whether at the range or away at a competition. Order with confidence knowing this is the correct OEM part for your Feinwerkbau rifle or pistol.
