abishai Posted July 19, 2013 Share Posted July 19, 2013 Hi guys, I have a Mossberg SPX with the Choate +2 and am going to be replacing the Choate Mag Extension with the Nordic +4. Can anyone give me an idea what length I should expect to cut the Nordic spring to past the tube? Thanks much! Link to comment Share on other sites More sharing options...
creeper1956 Posted July 19, 2013 Share Posted July 19, 2013 With the gun empty, the mag tube end cap removed and the spring relaxed and sticking out... about 12-13 inches of exposed length. C Link to comment Share on other sites More sharing options...
breakingcontact Posted July 19, 2013 Share Posted July 19, 2013 Creepers advice is good. It's tricky. Don't cut it too short! Nordic has instructions with their extensions I believe. Also...you have to find out what your individual gun needs the setup to be. Cutting 1 coil at a time is a headache but better than cutting too short. Real trick is seeing how it runs at the range with a certain spring length and not just how it cycles at home. Link to comment Share on other sites More sharing options...
abishai Posted July 19, 2013 Author Share Posted July 19, 2013 Thanks, guys. I forgot to mention I also have a GG&G low drag follower installed, not sure that should make a difference. Link to comment Share on other sites More sharing options...
abishai Posted July 19, 2013 Author Share Posted July 19, 2013 (edited) Also, is the Nordic clamp just for the addition of a rail? Or do I need that for physical support of the mag tube at a particular length? Update: the description on Midway answered my question. I suppose I mean, you think I'll need one for the minor plus/minus 2 in. that it will extend past my 18.5 barrel?

Thecelt Posted July 19, 2013 Share Posted July 19, 2013 you don't need the clamp for the extension that you have. they have been known to change point of aim point of impact. Link to comment Share on other sites More sharing options...

Shoot us a link to this Midway discription... so we don't have to search for it. (I'm incredibly lazy ) Link to comment Share on other sites More sharing options...

As it is, had to send the +3 back (trying to achieve 8+1), as well as the follower which the site states won't work with "older Mossbergs". Well, I thought I was fine since my 930 is brand new. Wrong. Link to comment Share on other sites More sharing options...

Wrong. Agreed. I recently purchased a new style extension for my Benelli. All the pictures showed it with a clamp. I arrived with no clamp, wtf? Reading the description, way at the bottom it said, clamp sold separately. My bad for not reading fully, but it was slightly misleading. On the plus side, shipping was fast and it works great.....

abishai Posted July 26, 2013 Author Share Posted July 26, 2013 So I have the +4 installed, and I cut it to 15 inches to start, and it took 8 right off the bat. Should I stop cutting, or is it possible that the Spring is too tight? When I gently hand cycle it, about 25% of the time it fails to pull the first round out of the tube. But it seems fine when I cycle it hard and fast by hand. So the question is, is there any telltale signs that the spring is too tight while manually cycling at home? Just don't want to cut any further before getting to the range, unless the problems noted are reason enough to continue cutting. Link to comment Share on other sites More sharing options...
JesseCJC Posted July 27, 2013 Share Posted July 27, 2013 Hand cycling won't give you much of any indication of what will happen. Take it to the range, fire it and make sure it cycles with ALL types of ammo you use and go from there. Mine sits at about 13inches past the tube on an 8+ and cycles everything so I left it alone.
