when i first return, I posted I lost my plunger for my knight usak. couple days ago, I was going cleaning some boxes out to from where we move stuff out of one room to another. I found it. yesterday in the mail i got an 3 way ignition plunger that was sent to me by an forum member.

now, the thought has hit me, the breech plug for #11's and one for 209.

Does the non plastic jacked breech plug for the extreme work on the knight usak?
