Nordic extension tube versamax

Tinkerbell can you point out where the CFO says this. I called and asked about 6 months ago and they couldn't give me a straight answer. Or are you interpreting the wording of the law yourself.
 
The stock spring is stiffer for sure and it never happened with stock spring that the last shell hung up. The way I test this is point the muzzle on the ground and release a shell . With the +3 extension and the spring that came with it , it does not have enough force to push the shell all the way back on the lifter for it to clip. With stock spring and no extension this is not a problem. Now I stretched the spring from 27 inch to 29 and put a 2inch plug in the tube because I could fit 6 3.5" shells . It helped a lot with spring tension but it's not reliable 100% like stock.

Can you measure the spring that shipped with your + 3 extension. Thanks !

I've got this extension and it's working well without this problem. Maybe it's reasonable they sent our the "same" one again, maybe try it? Got a faulty one initially?
I guess the only other thing I can think of is the follower is getting snagged on something, maybe some debris in the mag tube? Did you plug it with something while drilling or dremeling out the detents?
Maybe a faulty follower with some kind of rough edge... You removed the original for sure and only have the new one in there?
I'm guessing you thought of all this, but I'm just not sure a weak spring is your problem from your description.

The thread is the same pattern, true, but an 870 extension does not fit properly and leaves exposed thread inside the tube, unless you mod the fore-end or the "nut" on the extension to fit up.

makes no difference, i have a 2 shot 870 extension that fits 7 plus 1, and a 10 plus 1 extension. i throw my shotgun around and not an single problem over the past year. Fits like a glove.
 
To the OP as I have explained in detail, there is very little chance it is the spring we supplied, its not "weeker" its a different coil size and patten, I think we have just used out 10,000th spring on this style with our mag tubes.
we have sold many of these mags tubes, we have 3 v max guns at our shop and all of them shoot 7rds with no issue.

It has been noted that the shell cartridge stops can be be an issue on the versa max.
we have also asked if you gun is a versa max tactical, or a hunting model, how were the dedents removed"
the other spring I send you 2 weeks ago along with another S&J spring and follower is a "factory Remington police spring 7rds"
I would take you gun to a gunsmith to be looked at.
or ship it to us, we have been working on Remington shotguns for almost 25yrs.

Bah like I said before as soon as I removed you extension and run stock I don't have the problem . So it's not the gun . Anyways Nordic spring is on the way , if this works it's Definitely your spring. By the way the 870 police is pump action , not the best spring to put on a semi. You are truly the worst company I have ever came across for customer service.
 
so the problem lies in the extension and how the spring runs through it into the factory tube. Seems BBB is probably spot on with his question regarding how the detents were removed.
 
In the few that I've done. I find where the end of the factory tube ends can be a little sharp and the spring catches on it. A mild run around the inside edge with a stone in the dremmel cured the problem.

Thank you for your feed back.
Its always good to hear from and expert..

FYI as of today we have sold 372 of those versamax mag tubes with our long life spring
all of them work buy yours....
The other spring I send you is an 7 shot 870 spring , this came from Gravle agency aka Remington Canada, it is the same sku as the US modle Versa max tactical.
Thank you for reminding us that the Remington 870 is a pump gun, with over a 1000 870 shotguns we have built or worked on in the last 25yrs it seems I had forgot that...
Any one that knows my company , knows we will go out of our way to help people with issues, but I,m not paying you $35 for you to go buy a mag spring from Nordic.
Our offer stands send it back to us for a refund, or send us the gun at our cost and we will look at it.
 
Well BBB I know the gravel agency they shot with us in 3 gun :) the only thing I can think of is the welded lifter. With stock spring it works 100% . I will try using my stock lifter with your extension and see. Also I will look into the end of the magazine tube for sharp edges that may catch the spring .BBB, do you think it's normal with your extension installed that the shell won't slam back all the way and will not catch?? Using stock spring it slams right back and catches in the little groove. Keep in mind it's always the last shell that will sometimes on the lifter NOT all ! I will very soon find out .
 
If the spring is catching at the extension transition it makes sense that only the last shell would have the issue. If all the shells had an issue, then it's the spring or the follower, or a buggered up tube.
 
I forgot to mention the dipples were removed by a smith using an expender and a sleeve, the tube is perfectly smooth in and out !

k9 it is very odd and I just don't understand why.. if it had happen to any other gun we have or the clients using our tubes , even just 1 client it would say it possible
that said in all fairness anything is possible.
If you shoot with the guys from gravle, have Alexis the gunsmith have a look at the gun, he does all the shotgun problem solving/ gunsmith work.
at this point not having the gun here I just don't know, but something it hanging up if the last round is not reaching the shell lifter.
Now you have said you have replaced the shel llifter, lf its filled and welded, it is likely to be a benelli M2 unit that's been modded?
it would be interesting to see if that is the issue, if it is, you may be able to see where it is hanging up.
I,m going to search some of the US 3gun forums and see if anyone else has had this issue.

Shoot me an email and I will send you pics of my gun. The lifter is an OEM that has Ben welded and polished.MAYBE the front part of the lifter needs to be bent down a little to help that issue. If I can't figure it out gravel will look into it for sure .
 
Pretty nice. One thing I can think of checking, the front of the lifter has a 'wing' / 'lip' on its right side. The wing goes into a slot in the bottom of the bolt carrier. During live fire could your wing not be going in the slot?
