need a new breech plug

[crowhunter1]

need a new breech plug for my knight disc extreme having a lot of hang fires,knight says 3 to 4 weeks is there any where else I can get one sooner.

Lehigh Defense has bare primer plugs. About $39 shipped with the adapter for the bolt. Plug by itself is $16.50 plus shipping but it wont work with the old Knight NFPJ adapter. Lehigh ships pretty fast too and they make good stuff.

Adapter for the bolt Bare Primer Adapter, Knight DISC Elite/Extreme

Have you tried cleaning your current plug with a drill bit? Hang fires are almost always the result of a plugged up flash channel. Only a bit will get the hardened carbon out completely.

What primers are you using?

Bare primer or Red jacket?

oops bare primer I still have old set if need be I could put it back in,only had one misfire and one hangfire out of 20 shots today.

ok just ordered one thank you for the link,you guys keep saving my butt.

I hope you got the bolt adapter too. The original Knight adapter wont work with the Lehigh plug. The lip that holds the primer is too thick

Original is on the left.....Lehigh on the right. The older one from Knight will hit the stem on the plug.

I,ve got the bare primer,where the primer slides into the bolt face and you close it and it slides into the long stem

Well, that is certainly odd then because even the Knight plug (with the brazed in vent liner) should ignite BH209 just fine if the flash channel was cleaned like i said.

What primers are you using?

 

[crowhunter1]

winchester triple 7,Last nite I took and soaked in bore shine,after that cleaned it I can blow throught it now and see light now.

NOW we finally got to the root of your issue

DONT USE TRIPLE7 PRIMERS!!!!!! This has been covered at length to NOT use ML primers. Use a Standard Win209, MAG primers or you will keep having issues.
