Lets see.... I thought I could fix the problem with a new hinge pin as I am a terrible welder and I do not have a welder in the first place. So I put in a new pin from brownells, but I failed to fix the problem in doing so. Then my friend told me he could weld the barrels for me I decided to try that instead. I probably should not have replaced the hinge pin in the first place, but if I had a dollar for every stupid thing I have done I would probably own an Invincible grade not a VHE.
