This is a ridiculously tight, low round count cream puff that I purchased from the original owner. It has very minor signs of use. It has been completely rebuilt with genuine Feinwerkbau buffers, seal and spring on 1/7/2024 and is not broken in with perhaps 50 pellets fired. The original buffers were as good as new and were replaced based on age. It is a later dual spring model and a Beeman import. I have bought, rebuilt and sold 6 of these over the last few years and you just don’t find them this tight. $650 you pay shipping. Paypal F&F or you pay fees.
