EricS Posted December 31, 2013 Author Share Posted December 31, 2013 (edited) Ok, some pics. Sorry But it looks like I'll have to do these one at a time. The threads on the stock M3500 magazine tube with the Nut from the NC Nova extension. I'm pretty sure those are square buttress threads. Note that I did not cut off the unthreaded portion of the tube. Edited December 31, 2013 by EricS Link to comment Share on other sites More sharing options...
EricS Posted December 31, 2013 Author Share Posted December 31, 2013 The nut threaded on. You can see that it covers the magazine tube threads completely. It went on easily and hand tightened solidly. No persuasion needed. Link to comment Share on other sites More sharing options...
EricS Posted December 31, 2013 Author Share Posted December 31, 2013 The nut threaded onto the stock tube. I think it covers up perhaps an eighth of an inch of the extension threads. Link to comment Share on other sites More sharing options...
EricS Posted December 31, 2013 Author Share Posted December 31, 2013 The threads on the NC extension nut. Sorry but this was the best picture I could do. Link to comment Share on other sites More sharing options...
EricS Posted December 31, 2013 Author Share Posted December 31, 2013 The barrel/forearm join to the receiver. Nice and tight. I hope these are of some value. If I can answer any questions just let me know. I had zero issues mounting the extension. Link to comment Share on other sites More sharing options...
openclassterror Posted December 31, 2013 Share Posted December 31, 2013 It appears as though the threads on your shotgun are approximately the same width on the groove as the thread. On my shotgun the threads are noticeably wider than the grooves between them (almost twice as wide). Would you say that what I am seeing from your photo is correct? I will try to post a photo of my threads when I get to the shop in the morning. It could be a manufacturing issue on the tube, but the cap that came on the mag tube threaded on easily. My Nordic nut only went on about 2-1/2 turns before it wouldn't turn by hand. Wouldn't even come close to bottoming out like yours. There are definitely some discrepancies here, just trying to figure out if the gun or the nut is what varies. I appreciate the help! Tom Link to comment Share on other sites More sharing options...

On my shotgun the threads are noticeably wider than the grooves between them (almost twice as wide). Would you say that what I am seeing from your photo is correct?" I think you're exactly right Tom. The threads are very even and uniform and the spacing is the same is the thread width to my eye. In looking at the stock tube and comparing it to the extension the thread patterns match up as well as I can discern though the nut threads are sharper (perhaps rounder is a better description), not flattened like the shotgun's.

Butterpuc Posted December 31, 2013 Share Posted December 31, 2013 This thread and the M3000 thread have me quite interested...hmmm. Are the internals the same as best anyone can tell? I don't really have the need for a 3.5" shotgun, if I were to ever turn it into a hunting shotgun. But, with that in mind I already have a 3" 870 I could hunt with. I would be concerned about spring weights, and maybe the bolt weight working with standard 2-3/4" loads. It sounds like you haven't had any issues as long as you have stayed away from light 2-3/4" loads. Link to comment Share on other sites More sharing options...
EricS Posted December 31, 2013 Author Share Posted December 31, 2013 A few of the other posters have looked them over, or had others do the same, and as far as we can tell the only differences are the longer receiver and a stouter recoil spring (probably). Mine will handle 2 3/4" 3 dr. eq (1200 fps) 1 1/8 oz. 7.5s and 8s all day long. From what others are saying that's not a fluke. Since P.E.Kelley pointed me at this shotgun I've had nothing but good experiences with it, including from Nordic Components for accessories. I recommend the platform, whether the M3000 or M3500, unreservedly. I even got my brother in law hooked. He's picking his 3000 up next week. Mine will be seeing 3 Gun duty starting next month and every month for the rest of the year. Clean it, lube it and run shoot it. Try it with various ammo and see what she runs. My guess is most everything. Link to comment Share on other sites More sharing options...
Jesse Tischauser Posted December 31, 2013 Share Posted December 31, 2013 If your wanting just a 3 gun shotgun go the M3000 over the M3500 just like everybody does with the M2 over the Super Black Eagle. If you want it to serve double duty for slaying big birds get the M3500 just don't expect it to run the light 1 1/8 oz 1145 fps stuff. I've seen several Super Black Eagles at matches. If you feed it regular 1200, 1250, or 1300 fps loads your probably fine. Link to comment Share on other sites More sharing options...
giarc01 Posted December 31, 2013 Share Posted December 31, 2013 Gentlemen, I first 75 rounds I have shot out of my m3500 were light loads. About 50 were 1350 fps and the other 25 were 1200 fps. It never had any problems at all. Those 1200 fps were the Winchester Wal-Mart cheapo ammo. I will shoot more tomorrow but I don't think it would have any trouble shooting 1145 fps shells. I was also shooting when it was about 35 degrees out which has caused me trouble with other semi auto shotguns. Link to comment Share on other sites More sharing options...
EricS Posted January 1, 2014 Author Share Posted January 1, 2014 (edited) As a direct result of Patrick Kelley's sharing of his thoughts, research and knowledge here and in the M3000 thread I have subscribed to Shooting Illustrated magazine. I believe in supporting those who support us and Mister Kelley is deserving of both that support and praise for his work. Money where my mouth is as it were. I also fired off a thanks to Shooting Illustrated along with my subscription. Gun writers of Patrick Kelley's caliber are small and seemingly shrinking by the day. We are all very fortunate to have him in our midst. Thanks Patrick! Eric Edited January 2, 2014 by EricS Link to comment Share on other sites More sharing options...
giarc01 Posted January 1, 2014 Share Posted January 1, 2014 I shoot 150 more rounds out of my m3500 this morning. 25 degrees outside but it ran great. Most were 3 drams with 1oz shot. That takes it to over 225 light loads with 0 ftf or fte. This gun is amazing! Link to comment Share on other sites More sharing options...

giarc01 Posted January 3, 2014 Share Posted January 3, 2014 (edited) I got my nordic extension, low drag follower, and clamp. It fit with NO modifications. Threaded right down like the OE. Edited January 3, 2014 by giarc01 Link to comment Share on other sites More sharing options...
CJW Posted January 5, 2014 Share Posted January 5, 2014 ...and, one more subscription. Thanks, Patrick! You are a great representative of the sport.

BBoyle Posted August 21, 2014 Share Posted August 21, 2014 Just tried my M3500. Tried to break it in with 25 OO buck, 10 3" Magnum turkey loads and 5 slugs. Then I went to 3 boxes of bird shot. The slugs shot a little low at first but my cheek was really low on the stock and I only saw half the bead. When I was looking over the barrel it seemed to be poa/poi at about 22 yards. Have to get a few more boxes and try them out. All of the high brass shells worked great. I then went to the Federal Target Load 2 3/4 dram 8 shot at 1145 fps on the box. There were 6 failures to feed between 50 shells and also 2 failures to lock back on last round. All FTFs only needed me to recharge the gun. I also had A box of 3 dram 7.5 shot from Estate that said 1200 fps on the box. All 25 shells fed and ejected fine and also ejected decently out of the gun as opposed to the federals that were about a foot to my right. I will just shoot nothing but the 3 dram 1200fps stuff or better and hope that it continues to like the new diet. Both the Federal and Estate loads were 1 1/8 oz shot. It is amazing what 55 fps can do I guess. The stock tube holds 5 2 3/4 shells in the tube plus I was able to ghost load a shell (as already known). I may order a plus 1 if I can find one, local law limit is 6 max. I may find that with further break in the Federal Target loads will work but for now they will only be for practice. Looking forward to modding the gun and also competing with it. Brian Link to comment Share on other sites More sharing options...
BBoyle Posted September 2, 2014 Share Posted September 2, 2014 The Federals are still hit and miss. They seem to work most of the time but I was getting 1 fail to feed every other load of the tube. I also had some Super X 7.5s that go 1255 and I was getting some failures to feed with those even though they felt a little stouter than the Federal top gun loads. I will have to get some more turkey loads or just high brass loads and continue to try to break her in so she may be more reliable with the skeet loads. Just how wet should I keep the bolt? When I had a few failures I put 2 drops on the rail and worked the bolt back and forth and she ran 3 tubes without issue. Brian Link to comment Share on other sites More sharing options...
