loganzul Posted Wednesday at 07:57 PM Posted Wednesday at 07:57 PM The left firing pin nut on my trusty 1878 has come loose, and I'm trying to determine the correct size nut driver needed to tighten it. I checked the parts manual I found online, but unfortunately it doesn't list the size. Does anyone happen to know the correct nut driver size? Thanks in advance for any help Quote
