Toby Bridges did a nice report on this plug. His results pretty much mirror mine.

Thanks Grouse !

mine is on the way too!

Just ordered one too!

Just ordered mine also looking forward to it

Will these work in the Knight LRH?

They should, any series of gun based on the Exteme - Elite series

I have been told they will and have ordered one, so we will see! Tried calling them, but just get voice mail, so went ahead and ordered one.

Got mine today and it seems there is some problem installing.. first the primer holder was real tight and the bolt will not close all the way any one got any ideas ? why ..i installed it in a extreme

Ok, received my in the mail today too. Mine did the same as yours.

I have a Knight LRH which should have the same bolt set up as the extreme. However, the piece that fits on the end of the bolt (original Piece) slips on without effort.

When I went to slide the new piece in, it wedged about 1/2 way in. I had to use a small wooden mallet to get it to seat all the way into the bolt. Anyone know if that is how it is supposed to fit? Once it got it fully seated, the bolt slid into the gun and would lock down.

It will be a pretty major thing to remove it for cleaning as well.

I am also wondering it this is how it is supposed to be?

To be honest with you the primer adapter should slide into the bolt just as the Knight adapter does.

The problem may be the width of the slot in the primer adapter. If you look at the slot in the Lehigh it is a little tighter than the Knight adapter.

Dumb question time on my part.... When you installed the BP did you use a deep socket or the Knight tool? There is some question if the Knight tool will install the Lehigh Breech Plug all the way to the seated position?

Question for both of you? to make sure I am understanding - when you go to drop the primer adapter into/onto the face of the bolt it is not dropping in place? txhunter58 you are saying that you needed to drive the adapter into place???? Can you tell me where you think the bind might have been?

I had a burr in the slot that I saw before I installed it. I used an India Stone to remove it. This may be your problem.

The Knight Tool needs to have the ID drilled deeper for clearance as it was not designed for NFPJ Breechplugs.

HI thanks, i used the knight tool and the breech plug seemed to bottom out no more turning and yes i had to use rubber hammer to set the primer adp on my bolt face,the bolt still will not close all the way but with the knight system all works great maybe i got a bad one...any ideas..?/?

Yes, I had to drive it into place, and I am not sure how I will get it off.

Now a new problem. Fired off two primers. They both fired great, even had some flame come out the end of the barrel. HOWEVER, when I went to pull the bolt back, it would not come back. I had to apply probably 50 lbs of pressure to get the primer to let go (I use Remington STS primers)

I have had some primers stick after shooting before with the regular set up, but it didn't take anywhere near as much force to get the bolt back as now. I mean, I thought I would have to use my hammer to get it back! Not sure what I can do about that, but it won't be good in the field. AND that was with a primer only. What will happen when I have powder and a bullet in front of it???

LOOKS like we have a problem here.........some body should get a hold of dave and see whats going on here......wtf..

The breech plug is only recommended with Federal 209A primers. The Remington STS might be a fatter primer. If that's not the case the plug would need replaced.

Sent him an email

i did to, hope he works it out with us

It sounds like your Knight tool is bottoming out. Try using a deep well socket with an extension to make sure the breech plug is all the way in. It really sounds like it's not. If it is all the way in just email Dave with your problem. He will make it right.

Are you saying that Knight's breechplug or the conversion breechplug needs the Federal 209A primer only? If so that certainly limits my options. Dang

Also, where did you read that about only using Federals? Certainly not in the Lehigh website about the BP conversion

I will see what Dave has to say and will let you know.

ill try it but im seeing that others are having the same problem and after firing it the bolt still sticks

I think Grouse may be on to something.

I just tried my new Lehigh plug in my .45 and .50 Elite's and they fit fine on both. But, I previously had the Knight NFPJ installed in both and had already deepened my Knight B/P tool with a 5/16" drill...to get a full purchase on the Knight plug. I believe you will definitely need to do this to fully install the Lehigh plug.

Also, the Lehigh adapter fit on the 2 bolts was perfect.

I'll try some 209 primers tomorrow.

Those of you having a problem with closing the bolt on the new lehigh, please look at this picture and then let me me know what you are seeing.....

The 209A was the primer i recommended while testing the plugs. There is a wide variance with all the different primers. The tighter fitting primer equals less blow back with this plug. Of course your situation, i would not enjoy either. Theirs tight and to tight. Yours is to tight.

i tryed a socket but that bottoms out to i used my knight tool and it went a little more then thats it

That's what i thought. I have a Knight tool that's deep. My other Knight tools are shallow. Your socket cannot be fatter then the Knight tool. Or you can just drill out your current Knight tool a little.

My knight tool is 1.010 deep also, there is some thing not letting it cam over ive moved the bolt back and forth and it looks like in the primer holder is starting to ware some..any ideas

Well, I had two other primers (winchester 777 and cciM. Both stuck, but not as bad as the STS did. Again, I am not sure what they will do with a real load. Might be better, might be worse.

Well, already got an email back from Dave and he asked me to send the bolt piece back so he could see what the problem is. Hope I can get it off the bolt...........

As I said in my previous post.. I installed the new Lehigh adapter and B/P in my .45 and .50 Knight Elites.... both fit fine and the bolt cycled without issue without a primer. Note... I used a Knight B/P tool with the center drilled out with a 5/16" bit.

This A.M. I attempted to cycle 3 different brands of 209 primers (W209, Rem STS, and Fed 209a) and had the same issue with all 3. The primer would not drop into the adapter... and I had to apply serious thumb pressure to insert it. When I closed the bolt, the primers seated in the B/P neck fine... no problem. However, after opening the bolt and attempting to dump the primers... all got stuck in the adapter. I had to remove the bolt from the rifle and pry them out with a screwdriver.

The opening in the adapter appears to be slightly too small to accept the primer without forcing the primer in or out of it. See pic below of a W209 primer hung on the adapter opening/rim. (This does not happen with the Knight NFPJ adapter)

Not bashing here ... and I bet I could probably buff with some 0000 steel wool and try to fix it myself (not sure, but there may be some tooling marks on the edge of the opening), but I think I should notify Dave so he can address it.

Yes, notify Dave and he will correct that. My primer adapter i'm using is not heat treated. I bet when they were sent out to be heat treated this problem happened????

I notified Dave.

Certainly willing to give Dave a chance to get these right. I still think this is the way to go for the Knight's and BH209. If it was an easy fix... I'm sure Knight would have implemented it !

I especially like the vent liner concept. I'm finding I get under 400 shots out of a T/C Omega breech plug with Fed 209a primers before it starts getting serious erosion... along with blow back. My 25 ACP conversion has 3x that many shots with T7... and still no erosion.

Please fix this Dave.....I'm tired of messing with o-rings and drilling out Knight B/P's. :s2:

Got a refund tonight from dave..i hope he can fix the problem i still want to try one

+1 on the refund (I didn't request one).

Also noticed the Knight replacement plug is listed as "Out of Stock" on his site.

I am sending my adapter back in to Dave along with my bolt so he can see the problem firsthand. From the conversations I have had with him and several people who have worked on this with him, I feel confindent that he will stand behind this and have a fix. It also does look like it was "overengineered" to tight tolerances without realizing that the bolts. etc, that it was designed to fit, were not made to the same tolerances. Hard for an engineer to accept, that that is why we are here.

I really want this to work, so I have no problem letting them work the bugs out. Just as long as it is before next season! He did issue me a complete refund without me even asking for one. Don't know how you can do more than that at this point.
