leaking from breech

[FreshlyRimmed]

What is causing a leak from the breech area? It seems to vent right up through that area and through the feedneck.

oil your valve stem, it isn't seating properly on the other side, a little bit of oil should help the problem.

Oil the valve and make sure it is sitting right or it'll leak if it's not

Sounds like your bobbin and spring didn't go back in quite right. Shift things around inside the powertube until everything lines up cleanly and no more than a quarter of an inch of the bobbin lies outside the gun without the endcap/volumizer on.
