seized breech plug problem
 

i got an American Knight muzzleloader the other day and it is used..the person that owned it before me probably never cleaned it..I took all i could apart but cant get the breech plug out it is seized...any suggestions

Check the local auto repair garage and see if they use a product called Kroil™ , if that doesn't break it loose nothing will . If your suspicions about the previous owner's "hygiene" are correct then a siezed breech plug won't be the last of your problems with that gun . Check the bore , I strongly suspect that you'll find it pitted beyond use .

If your sure it is stuck bad... you might want to send the rifle back to Knight and have then remove it so you do no damage. MAKE SURE THE RIFLE IS NOT LOADED BEFORE TRYING ANY OF THIS.

If you really want to try and remove it, there are a couple ways to try and get them out. One method is to put the breech in a soup can and fill the can with a solvent such as liquid wrench or even hot water with soap in it. What we want to do is try and wet or saturate the fowling in the breech. Also pour some of that solvent down the barrel so it will get on the threads down there as well. After soaking it over night, place the rifle in a vice. I like to cover the locking lug and then put the lug in the vice. Then put the breech removal tool on the breech plug and tap on it lightly with a hammer or mallet to see if you can break free the plug a little. Then start trying to turn the thing out.

another thing I have done if the soaking does not work.

Another way is to put the barrel into the freezer over night and freeze it. Then have some water boiling on the stove. Take the barrel out of the freezer and put that into the boiling water and heat the breech end of the barrel up real fast. Now immediately put the barrel in a vice, put the tool on it, tap it with a hammer and start turning it out. If it will not turn out, then you will have to send the barrel in.

I think Brownell's carries it. Liquid wrench is also good. And, as a gunsmith, I can tell you that cayugad gave you some pretty good advice. This thing with heat and cold can make an amazing difference. As well as spending some time trying to soften the cause of the seizure - which is powder fouling and residue. At the end of the day I hope you don't go through all this and find out the bore is badly pitted anyway . . .

I bought Kroll Oil at Midway or Midsouth.. in fact they had a good sale on it and I got a couple cans.. never can have enough. Liquid Wrench works really good too.. they sell that at most large department stores and hardware stores..

One poster said that if the plug is stuck the rest of the rifle may be junk but that might not be the case. Old timers never took out the breech because you were not suppose to and they still cleaned the barrel and all othe parts just fine so don't give up on the gun yet. I use to be a big PB Blaster fan but last year Liquid wrench caim out with a new formular which is their best ever. If the LW you have is over a year old go get some of the new stuff.

The next thing I would do if I was you is get a socket, extension and ratchet that fits the plug and use that instead of the tool that comes with the gun.

Good luck let us know what you found.

I've had better success soaking the bore overnight with this stuff below. Then graba socket & socketwrench that fits the plug -then smackingthe handle a few times counter-clockwise with a hammer.

Hmmmm seems simple enough to me. Buy one of those $12 propane torches and take the barrel off the stock, put the barrel in a vise with a towel around the clamps, clamp the barrel firmly down and slowly heat around the breech plug area. Have your tool ready and when the breech plug area is hot enuff to sizzle water, put the wrench on the plug and give it a good forceful push to break loose the breech plug. Ive had to do this quite a few times due to the crappy non working anti seize they sell. After you get it out, clean it up good and buy some TC anti seize TAPE. Its the only stuff that will work in my rifle.

Don't have a torch?.... heat some water until you first see the bubble & pour slowly down the bore with the muzzle upwards using a funnel. When the water reaches the top of of the muzzle -- stop & let it soak for an hour.

Dump that water out - repeat this procedure -- except this time, only let the barrel sit five minutes -- until it gets nice& hot. Having a hammer,socket & socket wrench right next to you, dump the water & moderately tap the wrench handle with the hammer in a loosening direction inside a vise.

Some folks find success emerging the entire barrel in a filled bathtub overnight. I do not recommend that procedure -- small gaps underneath the open sights could get contaminated with water& form rust eventually.
