I've bought from WaffenCenter Gotha in the past and they have been most friendly and useful.At present I am in Italy, for the WFTC's. sorry for the delay in answering.If UMAREX is charging $100 for the repair and that includes the shipping, I would say go ahead.If it does not include the shipping back to you then you're probably marginally better off ordering from Gotha.One thing you need to check is how you cock the gun.Ideally, cocking the 48->54 should be a measured, deliberate movement. Reach the point where the safety pops out in the back and stop.These are, for the most part, robust guns that can last several lifetimes, but they do have their slightly less strong points.Good luck and keep us posted!HM
Also the moment I read your title all I could think of for some reason is….”the front fell off”
