I need some 11-87 help

[dw149a]

Recently purchased a new 28" replacement barrel for my 11-87 12g. The old barrel had suffered from some poor home "gunsmithing" on my part. I tried to replace the front bead-thought the threads were stuck and drilled it out. It turns out that it was a press-in style. Let that be a lesson to me and you.
So, I decided to simply replace the barrel with a new factory replacement.
After I receive the new barrel, I install it and take it to the range. No go. It does not fire. Firing pin does not touch the primer. I go home and totally tear it down. The firing pin is not broken, spring works, the firing pin moves within the bolt and protrudes correctly past the bolt face. What am i missing? Any help is appreciated! Thanks in advance.

Did you disassemble the gun to clean it at all? Check to make sure that the gas rings are in correctly. My dad had a similar issue and it was due to him puting the rings in backwards. If not give it a good cleaning and make sure nothing is sticking. Clean out all that old oil and gunk. Also make sure the gas rings haven't warped over time. Hope this helps

1100 barrel?

They don't work on an 11-87

Issue solved! I had tried to replace the barrel seal with an O ring that I had laying around in my plumbing supplies. The diameter was correct, but the thickness of the O ring itself would not allow the bolt carrier to seat properly with the rest of the gas system and thusly not seat well enough into the chamber. Lesson: use specified parts for specified application! Thanks!
