IF the salespeople at the companies you mentioned are trying to say an extension will fit a Mossberg, they're wrong. Forgive the previous insinuation that they're pulling something. To clarify, it is much more likely they just don't know. Due respect, but representatives from every company you mentioned call me on a daily basis with questions about what fits what. They're salespeople that handle MASSIVE product lines, and can't be expected to know everything about every product by every manufacturer. As a manufacturer, we're probably a teensy bit more informed about WHAT OUR PRODUCTS WILL FIT.

Choate is, incidentally, a manufacturer, too...I'd LOVE for you to show me the mag tube they make that ANYONE there will tell you fits a Mossberg. The people over at Choate know their stuff, and I betcha' if you call 'em, they'll tell you the same thing. Just a suggestion, though...who am I to say...



"Of course, one could also blame Mossberg's hard-to-accessorize reputation on the people who keep buying little sissy-guns like the 500 and 590 instead of the ones that take full-size ammo. "

don't roll your eyes at me!!

Good post. And yes, the replacement barrel will do just fine. However, to my understanding we were talking about an extension. One is a twenty dollar part and the other is over $100...fairly significant, if you're watching a budget.

Thank you for posting the items that Mossberg features w/ our products on 'em...pistol grip, heatshield (which is, arguably, just for looks) and replacement forend. Those items are available directly from Mossberg already installed (they MAY not be selling the replacement barrel and tube separately, though...ask 'em). If you'd like to dress out a gun you've already got, call one of the retailers you mentioned...Brownells, Midway, etc.

Read the last link again; riflestock.com is Choate's site.

Start from http://www.choatemachinetool.com/ and select "Products" "Magazine Extensions" They have at least four products listed as specifically (and only) for the 835, and several others for the 5500 and 935.

I had a couple questions about some of their stocks, so I've got an email in to them that also asks for confirmation of the existence of these extensions, in case they were a really obscure April Fool joke or something.

Two things about these products made by Choate (and very cool items they are)....

1.)Most importantly, none of those is a pump shotgun, they're all autos. Some relevance there, since we were talking about a pump (500,590 and 835). Differences are significant in lots of ways, especially if you're manufacturing stuff like mag extensions.

That brings up another good point. Since we're talking about a non-hunting application for a shotgun (presumably, unless you're going snow-goose hunting in the Yukon where there's no shell limit). My point is that VERY few armories are outfitting officers and soldiers with auto shotguns...they use pumps. Why?

a.) Chances of misfeed go WAY down with a Remington 870 versus an 1100...same with a 590 versus a 935.

b.) If there is a misfeed, the (misguided-but-oft-applied) means to clear the shotgun is to rack the buttstock on the ground while holding the forend, effectively forcing SOMETHING to happen. IMHO it is a great way to break the gun further and possibly blow someone's face off. Transitioning to sidearm is a much safer solution. Anyway, assuming you're using it in a 'tactical' (read 'home defense') situation, you'll be interested in similar rigs for your shotgun regardless.

2.) It will fit the 5500, the 935 and the 9200, but only one of those guns is still made. Again, we were talking pumps, and these are all autos. OF GREAT INTEREST are the ones they're saying fit the 835. I'm looking at my 835 AND the product in question, and I simply don't see how this is going to fit. Dave (our engineer) is trying to figure out what to cut on the gun to make it work...

Anybody called 'em????? (calling presently...details forthcoming...if I need to eat my big words, rest assured, I will)

Kind of a wierdness, but here is what I got after about twenty minutes on the phone with a great tech support guy who (vainly) tried to talk me through installing the Choate mag tube extension on my 835.

Apparently, SOME 835's were made with the bracket that secures the mag tube fashioned a little differently than the majority of the ones we've tried. It is ONLY on the 835, though...so 500's and 590's I'm still convinced can't be fitted.

My stoic 'IMPOSSIBLE' argument does have that hole punched in it, though...my face is a little red...

So, what is different about yours that prevents it from taking an extension? AFAICT, mine looks a lot like every Remington I've seen. I've considered getting another 835, and I'd like to make sure it is also good to extend.

Scot Van

I'm now certain that there are A FEW 835's that will accept an extension. I'm also certain that MOST won't. I've got four of 'em here that won't. In talking w/ the customer service fellow at Choate, he's got one there that has a removable endcap that simply screw off to reveal male threads. All of mine here are fixed and NOT removable. I don't know what to tell ya'll other than there are probably some oddball ones out there.

Incidentally, we work VERY closely with Mossberg, and even their shopguy was suprised to hear ANYONE was making one that would fit, even an 835. Presumably, ifyou've got one with a magtube cap that will unscrew, and you're not impeded by the barrel bracket in any way, go for it.

I'm BIG FAT WRONG that none of 'em could!

Still firm that NONE of the 500 or 590 line will take 'em, tho....

The threads (pretty much invisible in this photo) do seem somewhat shallow and coarse compared to what I remember on other brands, but this is, IME, the normal way, and IMO, the proper way for a shotgun to be held together. (Yes, I own a Norinco copy of an Ithaca 37 because it was cheap enough that I don't feel bad about throwing it in the trunk unprotected, not because I think it's good that Ithaca reinvented the wheel and got it wrong, and that Norinco didn't see an opportunity to make a name for themselves by fixing it.)

OK...had to check...they're deeper than I thought at .040 with lands .040 wide, and pitch is something near 12TPI. Threaded section is about .3" Does that sound close to any other brand's design?

Ummmm. Geez. I'm WAAAY in over my head. I'll hafta' answer you when our engineer comes in Monday morning, man. I'm a shooter and a rider, not a lather and a wrencher. I'll get that math for you early next week!

Details forthcoming....




Basset hounds got looooooong ears. Does that help!

No problem, just curious if a shotgun maker might have accidentally done something the same way as another maker. Given the trouble they go to in making sure that no two makers have the same threads on a front bead, I doubt it's possible, but you never know. Frankly, I'm surprised they all use the same ammo.
