How To Replace The Extractors On A Mossberg 835 Ulti-Mag



"So, LSP, if that's your real name which we doubt, how do you replace the extractors on a Mossberg 835 Ulti-Mag 12 gauge?" Good question, punters.  First things first, you put the beast on a Led Sled and take a photo with your not-so-smart phone. Beautiful, isn't it.

Then you reminisce about all the armed strolls through the country, dove down, skeet smoked, rabbits for the pot, ducks missed and general pump action shotgunnery. Good times, no doubt about it.






But here's the thing, it may be a deadly assault shotgun but only if the extractors work and the gun cycles ammo. Then it's banned in dhimmitudes like New Zealand, Great Britain, Australia and beyond. In those countries only criminals can own guns, so law abiding citizens are safer.

Reverie over you move to the task in hand, changing out the 20 year old (?) extractors and their dualist, Manichean springs. How? It's not hard, take down the weapon, behold the bolt, place it on two blocks of wood and tap out the pins which hold the extractors and springs in place. Then replace. Easy, right?





No, not easy, because the pins are held in place by dark Zeroastrian magicke, Pangea, typical. First you take a pin punch to the thing, tap, tap, tap; tap out the pin, LSP. Fail. The pins don't want to move because they're wedded to staying deep within the Solar Disc of the bolt.

Don't give up like some kind of RINO, fight through to the objective. For me, that meant moving the lubed up bolt to  a vise. Resist, Ulti-Mag enthusiasts, the urge to pound the bolt with a hammer. Instead, take a sturdier punch to the task and tap again, the pin should move. Follow through with a lighter gauge punch equivalent.





Retaining pins driven out of communion, replace the worn out qabbalists with new parts. It's easy enough, pop in the springs and extractors, hold the extractors in place with a retaining punch and tap in the pins. Do it in a vise, if you're me. 

Please don't freak out and pound on the immobile pins with a sledgehammer, that'll mess up the job. Stay calm and while you're at it it, remove and clean the bolt lock. You don't have to, there's no "rule," but I recommend it.





Then sit back and behold the glory of the thing. Two new extractors in an old bolt and a gun restored to fight again for another couple of decades. Right on, and you did it yourself as opposed to paying someone at Ray's to rip you off $200.

The Mossberg 835 Ulti-Mag began life in 1988 as an all-purpose shotgun, capable of handling small to big loads, 2 1/4-3 1/2". It retails at around $600, mine cost $200 from a gun show a decade ago, and features a ported barrel, tang safety and over-bored barrel (don't try slugs, kids). It's been a workhorse and worth every penny.





Buy one if you like, but be sure to spray the unpleasant camo on the new guns black. Better yet, go to a gun show and buy one at the right price.

Your Pal,

LSP

Like Mossberg? Like what the hell. Like we're trying to save the planet here. Like pay attention.....

I thought that you'd be munching on a brisket burrito and swilling a Diet Coke while performing the appendectomy, and that you'd be wearing scrubs as you vivisected the shotgun. I realize that those may seem to be 'unnecessary steps' but when is a brisket burrito unnecessary?

Bully, and well done. Savor the moment of self reliance. It is most satisfying to restore a worn old warrior and return it to duty.

Pins. Woe unto to those who fail to realize that the pins holding the front sight to an issue AR barrel are tapered. Fortunately, my introduction was at Small Arms Repair school.

Yes, Kid. And let's not forget that a functioning, extracting 12 is an asset in the save the world scenario.

LL, I was close and feasted on VENISON. But now that you say it, one of K's B&B burritos sounds pretty appealing right about now. C'mon, Lent, hurry up.

Thanks, RHT. It is satisfying and I'm looking forward to testing the old beast as soon as Texas dries out a bit from the recent global cooling deluge.

The old tapered pin gambit! Amateurs like myself thank God for Youtube infovids... speaking of which, these Mossberg pins were kind of a deal. But it all worked out in the end.
