Thanks and sorry for just now replying 4 months later .... The only sight I have on my 930 is the original waterfowl Fiber Optic front sight with no rear. I now have about 500+ rds through this 930 and it has seen a few more 3Gun matches where I have have been working on my reloads since that last video. The only problem I have had was a couple of weeks ago I had cycling issues but after getting advice on this site I took apart and cleaned the piston assembly for the first time and the gun is back to running 100%.

My 930 is back together and running 100% again, it was a dirty piston assembly. Mine ran about 500rds before having an issue. I thought I was cleaning it good but I did not know about the piston assembly / rings so I never took that apart or cleaned it. Thanks to all who gave their input and for those with 930's, watch that video and clean those piston parts but DO NOT remove the screw cap that holds the heavy recoil spring! Thanks again!

I have not gotten it back together yet. I planned on doing it yesterday but went shooting on short notice instead. I will make some kind of compressor tomorrow and post back my results. I can't say I'm happy about all this, what a PITA.

David, thank you. I did not know that I shouldn't remove the spring so when I unscrewed the cap all 3 pieces went flying and now I am guessing as to where the spacer goes and what it's oreantation should be towards the spring. I couldn't find a diagram for the parts breakdown anywhere. I think I will take a picture of how I have it and see if someone can confirm that it is correct or incorrect.

One last question, there are 3 pieces that include the threaded cap, spring and a spacer. Does the spring sit against the angled side of the spacer or the flat side? I inserted the spacer flat side down so that the spring sits on the angled side of the spacer is that correct?

Yes Sir, I just found that out the hard way

I completely tore it down to clean it today and even removed the spring ..... now I can't get it compressed to re assemble it. Tomorrow I will make a bolt / washers compression rig for the spring like shown earlier in this thread but for now I am stuck un assembled. Joe, I see a little wear on the mag tube but nothing major or alarming.

Joe, I haven't noticed that but I will check. I might tear it down tomorrow and if not then Monday. I knew this would be a good place to start trouble shooting. Thanks.

I just developed the same problem. I have a 930 waterfowl build, cut to 22", +4 Nordic that I have run hundreds of Walmart bulk pack Federal Multi 2 3/4 3 DRAM 7 1/2 through without issue until last week. The 930 was cleaned and lubed right before my last match, ran maybe 80 rds through it without any issue at the match and then it was put back in the safe. Went to the range a few days later and immediately had cycling issues, same ammo and no changes from my match a few days prior where it ran 100%. First round fires, bolt goes foward but stops just short of going into battery and I get a click instead of a bang. If I fire a round I have to assist the bolt foward into battery then it will fire the next round and I have to repeat that process every time. I came here looking for help as I have not been able to take it apart and troubleshoot it yet and it looks like a few others are having a similar problem but with varying round counts. I am going to clean it and focus on the piston assembly but I feel like there may be something else going on especially since others have cleaned and lubed without fixing the issue, any other ideas?

Just wanted to say thank you to all of those who were involved in making this match happen. I had a great time and it was nice meeting everyone.

Thanks for the phone call, I'm in. HLG, thanks for the info and hosting the event.

I'm running a TA33RH ( red horseshoe ) and am considering going to a 1-4x variable due to closer shots being tougher with a fixed 3x. What is the closest distance that you will be shooting? I am looking forward to hearing your comparison.

2 1/2 months later and this 930 is running strong, still not a single malfunction.

This is my 22" 930 build with a Nordic +4

Have you ever loaded to capacity with the +4 extension and had it work properly or is this this first time loading the +4 to capacity? Did you measure and cut the new spring when you installed the +4 extension? I have the same setup and I haven't had a single problem running 7 1/2 bulk pack from Walmart.
