The screw is all the way out but because the screw hole on the BnM breech is a liitle deeper, it just won't slide out..ggggrrrr wasted part of my day with this $#@$ thing lol

It's a little flat head.....i got some new ones from Magnum i want to put in. They look real good to..

Any ideas or suggestions appreciated

Thanks

Yeah i tried the little magnets I have, maybe I need a stronger one. It gives me the willies If had to drill into it, that would be a very last resort.

Bang it upside down on a piece of wood?

Small needle nose tweezers?

If the screw is unscrewed? and no longer threaded into the maintube. Why not remove the rear screw and pull the breech off and push it out from the bottom?

Ahhh....I got it! Now he bolt on the rear of the breech is really bad and it's a flat head. I had to grind the head away a little so it would fit down the breech hole to fit. I must have screwed down to much because the head of the bolt is jammed. I'm trying to drill it out, it's a mess. These BnM breeches are a lot higher then the crosman.

Jeez what tooling are you using to assemble these?

Are you still messing with them not popping out of the countersunk hole? If you put it in, you should be able to take it out.

I'm using a flathead screw driver. First time problem with this back one. If you don't have a high rise breech you might not now what I'm talking about.

I had a Gmac Custom. Never had a problem... Normally came out after I tilted it upside down.

Well I guess your a star! Not sure what your getting at....it usually does just come out as I said it's the first time I had it happen at the back. Some how the head got jammed I probably over tightned because I'm always having a problem with a Tippman adapter coming loose.

Sorry no need to be like that.

You squirt some oil in there? Shouldn't require more force to remove than installed.

No I wasn't. I was answering your question about the high rise breech. I know you're frustrated, But don't get lippy at people trying to help. No matter the questions.

Drilling it out just going to damage it more. Risk of damaging the threads, and enlarging the holes. Forcing you to probably D&T to a larger size. Then stuck trying to get it out of the end cap.

Have you tried oil, and some heat? Or screw driver with a bar on it. Push down and use leverage..

Those stock adapters do they have a built in power adjusters? Maybe its turn in enough and screw your trying to get out is long enough that the PA acting like a setscrew locking it?

I can still turn the PA , I can feel a little resistance, so it could be touching it like you said. I'm not drilling it anymore. The head is to damaged to turn now at all. I might half to take everything a part. I'm using Crosman flat head rear breech bolt, that i have to grind the head a smaller diameter but when I look at other high rise breechs. They seem to be using cap screws, I didn't realize that, I wouldn't have had a problem. i bought this breech used on here a while ago.

The only explanation I can see is I grinded the head diameter of the Crosman bolt, flat head too much. Being it's a flat head didn't give much for the screwdriver to work with. So when I screwed down the head, it just barley caught to hold the breech in place and when I over tightend it slipped right through where it was suppose to catch. So now the screw is drilled out and jammed. It still cocks fine but adapter is a little loose. when I get a new adapter, I'll worry about it.

Thanks for the input!

Ah Improper screw driver used. Why I like using hollow grounded screw drivers. Can get a kit for 23 something dollars. Contacts the whole channel and not just the tip.

Flat heads awful......I was just reading a post from GTA about using heavy hammer springs like a .45 wire with that BnM breech a a Discovery tube maybe that's why the Tippman adapter keeps coming loose. I never thought about that. Discovery was made for a 20 fpe gun, not with such a heavy hammer spring. You can get carried away with modding and not realize some things.

Didn't know about that type of screen driver...where so you find?
