Hi all, I just bought a 2 shot mag extension for my 870. It is a used extension and the guy that sold it said the spring might not be the right one but will work. I tried it out and it went togeteher, but will not accept the +2, only 1 extra shell. i believe the spring is too long and is stacking inside the mag. The new spring is WAY longer than the stock spring it replaced, for the extension only being 6 inches long. My question is: Does anyone know the proper length of the spring for a +2 application. I suppose I can just cut the spring and it should work. No rocket science here right? I just hate to do the old cut and try thing a dozen times, so if anyone has the right number, it would be GREATLY appreciated. Thanks in advance, Sam |

I agree with Prone. expresses have little indents that prevent the addition of a mag extention without dealing with them (drilling out what not) but be advised it will void warrenty, but if the gun has worked, it will work... its a 870. That being said. 7-shot----------32" 8-shot----------34" 9-shot----------37" 10-shot--------40" These are estimates, but it should get you in the ball park. And yes it should be a good deal longer. And here you go for the indents: http://www.hunt101.com/img/307304.jpg Thanks to Wetterman for the image in this tread: A thead dealing with just the extension |
| The spring lenghts listed above are the springs lengths provided by jon tank from tanks rifle shop. I will measure a few of mine when I get home since I need to clean my new firearm. But yes, the stock vs extension had a good difference on them. I was in the same boat when mounting my extension.. what the hell, this is suppose to fit here? It did, and I can still load 6 rounds. |
