Vulcan leaking through barrel

[hsnmz]

Hey guys

I have a Vulcan Tactic (first gen) that has started to leak through the barrel. Any ideas how to fix it. Thanks

If the hammer isn't too tight and or doesn't stop when you cock the rifle, sounds like a bad valve or seat.
Am I even close guys?

That’s right, a leak coming out of the barrel is a leak at the valve seat (poppet). Could be as simple as a bit of trapped debris that needs to be cleaned away, or a surface flaw that can be remedied by lapping the surfaces with an abrasive slurry. Worst case it’s cracked and needs to be replaced.

Thanks guys for the replies. You saved me from taking apart the whole gun to find the leak.
