I went to the range with my girlfriend and her parents this weekend, which was an awesome family outting!!! My gf's father had a Lakefield Mossberg 12 gauge that was over 40 years old. I realized that at times the empty shells would stay lodged in the chamber even after after we cycled it several times. It took a really hard pump forward to make the extractor grab that empty shell and pull it out. I figure that maybe the extractor needs to be changed, and so I was wondering if this model of mossberg would have the same extractor as the Mossberg 500 of today.

I had a similar problem with an old .410 the other day. Seems that the extractor is a little worn, where there's supposed to be a hard edge that grabs the spent cartridge out, it's a little rounded. I found it to be more an ammo problem though. I fired some really old shells, that i figure maybe the brass is a little worn from banging around in a shoubox for the last 15 years, some of them were a little green :O and all definitely had a black patina on the brass. These are the ones that stuck. I opened a brand new box of slugs and it shot and extracted them just fine 
When i got home, i cleaned the chamber with a .45 brush really well, and soaked er down with silicone oil. Tried the dirty old shells again, after cleaning the brass, and no problems.

Maybe he has a lot of gunk around his extractor and it needs cleaning. I tried taking it appart but it was way more complicated then other shotguns I've delt with in the past. According to the manual I found on the mossberg website, I need to remove the whole trigger assembly before I can take off the pump action and bolt (if the designe of the 500 hasn't changed in the past 40 years or so).
Does anyone have any experience with the Lakefield Mossberg 500?

If it's the same as the newer models, open the action halfway, and unscrew the barrel screw out of the tube, and the barrel will come off. There should be a single pin holding the trigger group in place, and it shoul dpop right out after removing the pin. From there, everything just kinda pulls out with your fingers. There are a couple of excellent "mossberg 500 disassembly" videos on youtube, and you should be able to tell within a few seconds whether it's the same or not I was surprised with my 500 at how easy it is to disassemble and reassemble. I can do it in about 30 seconds now.

I have to say that field stripping my Fabarm and 870 is much easier. It just seems that mossberg could have made it easier to clean without taking out the trigger assembly.
I have the same shotgun, a Lakefield Mossberg 400G. They don't like the real cheap ammo with the tin heads. No problems with Win Super Target, Federal Top Gun or Rem Gun Club loads. Or any loads that have brass heads.
Clean it anyway. The magazine tube will unthread from the action as well, to clean the mag spring. Mine is spotless and polished inside, still doesn't like cheap bulk pack ammo.

My (New) Mossberg 500 eats absolutely anything I run through it. The bolt could probably use a good soaking. I've disassembled an older Mossberg, and it comes apart exactly the same as my own, and as was mentioned above. When you do it the first time it seems complicated, and reassembly kind of requires three hands. After you get the hang of it, however, it's nothing!
