I've got an old BSA Meteor that fires every time you return the barrel to the firing position after cocking. VERY DANGEROUS!! Nearly lost an eye the first time it happened. I've had this gun for a very long time and have lots of good shots with it. Brought it from germany when I moved here. I live in Arkansas and there's no one here to fix it for me. Can any one help?

One of several problems that I can think of. The simplest is that the trigger sear engagement need adjustment. Adjust the sear engagement screw if it has one. Next up is that trigger sear engagement spring is weak. Remove and replace if necessary. 3rd is that the sear is worn and R&R . Lastly, the piston sear is worn which is the last thing I can think of. That means replacing the piston. You didn't mention the age of the gun aka the Mark. The Meteor has been around a very long time. Different Marks have different construction.

I agree the trigger sear engagement needs adjustment or weak spring. I had a shooter that did the same thing but solved the problem with some quick adjustments. :) Ed

i got a bsa meteor. the trigger adjustment screw is out of adjustment. Turn it out 1 1/2 turns and carefullt recock it.if it fires again, keep turning it1/2 turn at the time. the moment it cockes and holds, BE CAREFUL. the trigger will be as light as it can go. for safety's sake keep turning it 1 full turn. the BSA meteor does not have a safety so having it to close to his let go spot is somewhat dangerous. also be careful while you make the adjustments. hold the barrel at all times as it will shut violently if it does let go while open, possibly damaging the action and or stock.

This gun is old. I don't where to find the age or Mark to identify it. There's no safety if that helps get it in the ball park. ithaca gun co. on side of barrel and BSA gun ltd england on top of barrel.

you got the serial number? you can figure out by checking on that.

If you guys could see the blank look on my face. I don't know how to work on the gun. That's why I said there's no one around here to repair it for me. I've noticed that there's a large number a machinist on this forum. I'm an electrician by trade and there's no wires on this gun. Shadow, I went to that web site. Seems to be down. Waited nearly ten minutes for a page to load. Never did. Any place I could get it worked on or a complete rebuild kit.
-
howie1 rebuilt mine before i bought it and he did one hell of a job. Ask him, maybe he has got some free time or can direct you to someone who can. but really the trigger adjustment is a 1 screw deal... try that for now.
-
For serial # try looking underneath next to where spring cocking arm attaches to the Barrel ( its sometimes filled with that black paint stuff they use) the first 2 letters will tell you what series you have ans year. TW chambers web site has a table that will let you pinpoint what it is you have:) Tony
-
magnum... you have one too? mine is a MK5 1979
-
serial number ng95422
-
i"m on TW chambers, where do I find that table?
-
ng is MK4 1973-1978/9
-
Thank you very much. I remember when my dad brought it home to me but he passed in 04 so I can't ask him. Also the reason I want to rebuild it.
-
magnum is offline, do you know where the table is on the TW Chambers site. There are two sear models and they are dependent on the year the gun was made.
-
your number NG is a MK-4 model click on MK-4 and see exploded view:) http://www.gunspares.co.uk/shopdisplaycategories.asp?id=24305&cat=Meteor , . Mine is 1970 year model it is quite warn but still shoots.. I remember when my dad took me to buy it , saved up every cent for it about $33 bucks if I recall:) Tony.
-
you said earlier there was a table at TW that i could find the exact year. I'm on the site now but my gun looks like the mk-2. it does not have the rubber butt pad. They don't have the sear that i need anyway. Can anyone fab one for me. I will order the tune kit for the mk-4 and hope to get a new sear.
-
Hmm ..Your right. Thinking now it must have seen it some where else, it was last year and memory is not as good as it was:( all I can remember is that the serial numbers and the first 2 letters are important for year identification for example... there was like 4 runs of the MK-4 the NB, TB, NG and the TG.
-
followed the advice and got the misfires to stop. Took a look at the sear and noticed it was worn down to the nub. If i bump the stock with a mild blow the gun will still fire. Is that something that that could be fixed with a tune up?
-
I would be very careful with the gun for sure. Many of the old guns still around that have been shot alot do have wear and few parts availability.
You might want to check around your area for a machineshop that could make you a new sear if no other options are available. The other problem very well might be that the sear capture slot in the piston may be worn also and will need to be refinished. I certainly wouldn't do one without doing the other.
-
i would give it anothet 1/2 turn to a full turn on the screw. if you are not out of adjustment it could stop the bump firing. Mine did the same when i got it and an adjustment on the trigger saved it. you don't loose anything when you try...
-
I frequent CW Chambers often. On some BSA models they sell the complete trigger assy. I have bought them before for some of my customers guns. You can send them an email and they usually will get back to you the next day. They are very good at what they do and sell. Prices are not all that bad and shipping is very quick.
Like Bob said be very careful with at BSA. Any springer can be very dangerouse if the seers wears out. Do not foret to look for the adustment screw. It may just be as simple as adjusting your trigger. Most likely you may have to remove the stock to get to it.
