Re: Mossberg 930 Autoloader Magazine Extensions
Got a great deal on a TacStar 8 Shot Magazine Extension for my 930 - on Amazon and I had a gift card, lucky me from the holidays. Install = piece of cake and the connection transition is smooth - a perfect match but, the ammo would not cycle properly. I'm a city boy so I'm not in a position to take it to the back yard for testing but all indications are that the spring was weak. I lined it up against the stock spring and it is only 3" longer in total. I reassembled to stock to check the action - perfect - so I ordered a Nordic + 4 spring for just a few bucks and will try and fine tune using that to find the correct length. Springs can be tricky considering wire, wraps, gauge etc. so any thought will be appreciated. My plan is to start long and carefully find the balance of what fits and functions properly. The 8 shot is the longest that Tacstar makes so going to them for help didn't seem like it would do much good - i may make a call just to prove that out.
