FWB 300 vs HW 55

FWB weights more than the 55 .
(new PC here /windows 11 sucks / haven't got the camera figured out yet .)

Look for an FWB 300 Junior. It is a very nice little rifle.

I've owned both an FWB300 and a 55M. The FWB is a heavy weight airgun but it shoots rings around any 55. Also, the FWB 300 has a superior trigger and is a side lever cocker where as the 55 is a break barrel and has a refined Record trigger that is pretty darn good too. The 55M is much lighter and very high quality and the FWB is even higher quality in my opinion. Also the spring piston in the FWB 300 is engineered such that you can get an almost infinite number of shots before ever needing to be rebuilt because it utilizes steel seals in the compression tube. The FWB also uses a sledge system that allows the barrel to recoil so that there is virtually no recoil of the gun during the shot cycle - this system adds a lot of weight to the airgun and is why the 300 is much heavier than the 55M.
