Yes it uses the orange discs, I just wanted to make sure before dropping the cash on the bolt.
Then yes you need at least the Bolt and the Lehigh conversion should fit. Due to differences in tolerance there is a chance you might need a little sanding on the bolt face for it to work. Most that i know of did not need any alterations but it is a simple fix.
My GMB54 was listed as might not fit and it fit perfect.
BTW that is a SUPER NICE Knight. The Original MH series were outstanding guns and IMO are still one of the best. Sometimes you can find the red FPJ bolt conversions on GunBroker a bit cheaper too.

I finally got around to installing Extreme conversion and the Lehigh breech plug, it went very smooth until I put the bolt set screw in, if I screw it in any further than 3/4 of the way or so the bolt will not open any more than 1/4 to 3/8". Any ideas?
Also are there any decent one piece scope mounts like the Durasight or DNZ available for this rifle?

It closes fine, it just wont open after the set screw is put in. I tried to call there today but no one called back, will try again tomorrow. I would like to convert it to the quick release, maybe that will cure the problem at the same time.

After looking over the situation again and it ended up being that the diameter of the end of the supplied set screw was too large, I put it in a drill and sanded it down until if fit into the slot in the bolt easily.

The one that came with the conversion kit was a little smaller in diameter so I used that one and just kept sanding till it fit, it didn't take much just make sure to work the bolt a little to make sure you are in the bolt groove.
I ordered a Quick Release Bolt Screw Assembly #008462 from Knight and am just waiting on the 1/4-36 tap. This looks like a much better system than removing that screw every time you have to clean it.
