Del foro ingles air arms owners club
’m new to Air Arms guns and I’m looking for some advice please. When shooting my HFT 500 I suddenly got a really strong blast of air in my face. I checked, and as I expected the breech o-ring was gone, so I replaced it. There was still a lot of air so I checked the transfer port o-ring and that was split, so I replaced that as well. There is still quite a noticeable blast of air going forwards from where the barrel leaves the bolt housing, but not back from the breech. I double checked the o-rings and they seem fine.
