I have a 2017 knight mountaineer in 45cal. 1/30 twist. It's got between 1200 and 1500 rounds thru it. It has a full custom asg ignition system in it. Plug sleeve asg Gen 1 plug. And bolt nose for asg modules. When I first got it back I noticed bolt wouldn't push down all the way like it did with red plastic jacket. Was told this was normal as the modules get shot it will slowy close down more and more over time and use. When it finally closes all the way they might need replacement. The rifle shoots great! What I've noticed though is the receiver is wearing. Where the bolt handle makes contact with receiver. I have some 22 rifles made in the early 1920's that have this problem. Messes up head space. I think this mountaineer head spaces there also. For lack of better way to explain it. Replaced modules cause they started leaking. New ones push in and bolt closed all the way down. It isn't leaking but only have one firing on them. Is this receiver wear problem common on mountaineer models? I can't help but wonder if this wear hasn't really shortened the modules life. I mean I got over 1200 shots out of first 20 modules. And now the bolt bottoms out with brand new ones. All replies r welcome. Thoughts and fixes please.

sounds like a custom plug might be in order? slightly longer shoulder and you will be back in business.

Thanks for your reply and fix idea. I see from reading u do alot with inline muzzleloader shooting. I'll keep your fix in mind. The gun isn't leaking at primer pocket yet , however last time it got where it closed like this it wasn't many firings till it did. If I'm understanding this rifles design properly. And I might not be. Lol. It seems they built it like this to help with industry standards of excexptable tolerances. And different 209 primer lengths. The receiver is cammed r rounded for lack of better way to explain it. And that let's the bolt lug on handle float a bit. Again for lack of better way to explain it. It holds no real pressure so as long as its got enough bite on it no problem. Alittle more r less closed is fine. Anyway that lobe gets wore flat. Now there is no camming action. Closing in the erea by increasing shoulders length would just give me the same problem.
Maybe not though, worth a try maybe. At any rate it's not leakage that I'm trying to fix. It's module life I'm concerned with. Once that lobe is gone its just in a fixed position. No fudge room anymore. Hopefully I can get 5 r 6 firings out of a set of modules before they leak. I'll just retire it for hunting gun. Since modules r kinda pricey lol. Sure be nice to get 1200 shots out of 20 modules again. Just screening replies and fixes for now. Any thoughts r appreciated. I'm told these modules change minutely after each firing. Brass flow and just wear from being inserted and removed by bolt. The camming action of the bolt lug keeps up with this change. All I know for sure is once it closes all the way things r set. It is what it is. And it's not long till they leak. 5 reprimes on 20 modules is ok for hunting gun I suppose. I'll take one and fire and reprime till it leaks Hopefully it will take a dozen. Maybe time to retire it from target shooting. It's just hard lol. Gun shoots half in. Groups at 200 yards. Bottom line is no one at knight probably every thought there muzzleloader would get shot so much. After all there just for guys that want extended hunting seasons. Lol. Maybe get shot 200 times as it gets passed down the family. I suppose this is what happens when I buy a gun meant to be sighted in and then hunt. By 3 boxes of shells when u bought it. 20 years later still got half a box. Lmao. Never thought people would target shoot with them. I think they're catching on now though lol. Wonder what perrigrine will be like. Hopefully it has better bolt design. No more lug on bolt handle. Receiver softer than bolt lug. Bad idea. Should a made it other way around maybe? Could just replace bolt. Be fast easy fix.
