Nuke8401 Posted August 19, 2012 Share Posted August 19, 2012 Hard to tell from pic. Lookslike piston spring is scraping the tube. Does the piston go on the tube easy when not in the barrel. David E. Link to comment Share on other sites More sharing options...
EvilBetty Posted August 19, 2012 Share Posted August 19, 2012 Anyone notice this on the bottom of your gas tube? Check for a bur on the gas relief spring in the barrel. Both my 18" and 24" barrels scratched the crap out of the tube. I took a grinder to it and fixed the problem. If you want to have some real fun, take the spring out of the barrel! That's not really that much fun, but putting it back in is a blast!!! Hmmm... tempted to send it to Mossberg. Link to comment Share on other sites More sharing options...

It had the same problem till i de-burred the spring. If you have a roto tool, it just takes a few minuets to fix it. In fact, i doubt you could box it up in less time. Take some fine sand paper and smooth out the scratch on the tube. I think if you look you will find the scratch is forward of the piston and should not effect function at all. BUT, i have not seen your tube so this is all speculation. Certainly worth a look though. Link to comment Share on other sites More sharing options...
E53X5 Posted August 19, 2012 Share Posted August 19, 2012 I have 3 930s, and all 3 of them do this. I've always thought it was part of the design... Link to comment Share on other sites More sharing options...
Smokecloud Posted August 19, 2012 Share Posted August 19, 2012 (edited) Anyone notice this on the bottom of your gas tube? Yep, mine looked the same. couldnt hardly get the gas piston to slide over it, had to use a file to smooth it up. It came from the factory that way. I tore it down when I got it out of the box, was very disappointed to see it. I figured it was from their tooling and carelessness.

yvette Posted August 21, 2012 Share Posted August 21, 2012 Their CS does stink. No one seems to know what is going on, and they seem to just make up something when they don't know, instead of tracking down a correct answer. I assume these are pretty low paying jobs or pay is tied to how many calls they handle, or both. When Edna left we lost the one person who was aware, seemed honest & willing to look for info.

Looks just like mine, it was a real pain to remove and install the barrel until I cleaned it up. Cleaned it again today and felt around in that spring. Only can feel the slightest of a catch in the middle. Feels like a two piece spring or a large c-clip or something. Doesn't fee like it would be able to create this kind of damage though.

rln Posted August 22, 2012 Share Posted August 22, 2012 On mine it was the very end of the spring. I think when it was cut it curled that sharp tip towards the inside of the spring. It didn't protrude much at all, but it sure dug into that mag tube. Link to comment Share on other sites More sharing options...
Buckeye67 Posted August 25, 2012 Share Posted August 25, 2012 (edited) So far at Rockcastle, my 930 has crapped the bed both days. failures to feed yesterday and failures to fire today (during the stage 6 - the aerials... 50 seconds in penalties). This is shooting Federal high-brass #6 shot. My brother is having the same issues with his this weekend (his ran well when he got it). C'mon Mossberg, you can do better than this. ETA: I have the mag tube scratch as well. Edited August 25, 2012 by Buckeye67 Link to comment Share on other sites More sharing options...

Outsydlooknin75 Posted August 25, 2012 Share Posted August 25, 2012 Talked to the master of 930's yesterday, mine shit the bed on Friday on stage 8 and I've been running a backup ever since. Jerry said that I probably need to take the gas rings OFF the piston and clean them .... AND clean the tube where the piston goes in with a stainless steel brush. Especially if you shoot a lot of slugs it will foul up pretty good. I've cleaned the rings on the piston but had never cleaned them off of it. So when I get home from Rockcastle and when its time to clean guns I'll be pulling the rings off and cleaning the piston tube on the bottom of the barrel with a brush on a dremel. Also make sure the gas ports in the barrel are clean. Jerry said what it sounds like is that the piston is not going all the way forward like it should due to friction on the piston.

fueddy Posted August 26, 2012 Share Posted August 26, 2012 When u say fail to feed do you mean the rounds aren't coming out of the magazine tube? Link to comment Share on other sites More sharing options...
Buckeye67 Posted August 26, 2012 Share Posted August 26, 2012 It spits the round out of the tube onto the lifter (mostly) and then doesn't feed into the chamber. Yesterday's failure only came 3:4 of the way out of the tube, and I had to pull it out the rest of the way with my finger, then hit the bolt release button Link to comment Share on other sites More sharing options...

Geez, we get that you hate mossberg as well. I own a few tube guns I just use them for Tac optics and heavy metal. As for Mossberg I had high hopes for this gun but it seems to be having issues. I personally had problems with two Mossberg pumps I owned a while back. The first being a 500 with a 28 and an 18 inch barrel. The 18 inch barrel would leave the spent cases stuck in the chamber every 4 or 5 round when slugs or full power buck was used. The 28 inch barrel worked fine. I figured it was a fluke. I tried a 590 and had the same issue. Never tried another Mossberg after that. I hope Mossberg gets these guns worked out as the price is right. But it seems that they are having issues based on posts like this here. Pat Edited August 26, 2012 by Alaskapopo Link to comment Share on other sites More sharing options...
dskinsler83 Posted August 26, 2012 Share Posted August 26, 2012 Is Benny Hill still offering his 939 package and can you still buy a 24" barrel non ported from Mossberg directly?? Link to comment Share on other sites More sharing options...
