Well after 12 seasons of duck and goose hunting I took apart the spring tube assembly in the stock of my AL 390.It was a messy sight with the spring,the spring rod and parts of the tube in various stages of rust.After scrubbing, cleaning,lubing and putting the gun back together, I now have a single shot rather then an auto.I can feel that the spring is not working too well.I can't believe the gun worked so well for so long, rust and crud must be a good lube! My question is: Should I replace the whole tube assembly or just the spring? The spring is very rough but the little metal rod it attaches to (on the receiver end) felt corroded also. May be too much friction in the tube???Thanks.

Welcome to SGW Robski. You should try to clean the recoil assembly at least once a year and after the gun gets real wet like when the stock gets dunked.
If you think it will be taking on quite a bit of water the Sure Cycle kit from SRM might be a good way to go.

Robski,
You might have assembled the gun incorrectly. In particular, the connecting rod may be turned upside down. If the bolt is assembled properly and the connecting rod is properly inserted into the cup on the front end of the recoil spring, and the spring & cup have adequate lubrication, then the bolt should retract easily and slam shut forcefully when released by the bolt release button.
Or, you might have left out the gas piston or gotten the gas ports clogged while doing additional cleaning. Or you may have left out the gas relief valve spring when reassembling the gun.

Thanks, to all who replied. I have looked things over and I know that all is back as should be.I have taken the gun in to my local gunsmith/dealer ...they deal in Italian guns.I think I just let the spring get too damaged. Not cleaning the spring and tube;hunting from October to January in solid rain,etc., for a decade, with the same gun has finally done that part 'in' ..I hunt on the west coast of B.C.. It it so wet that it is not unusual to have 20 days of straight rain.My duck gun is usually soaked.I should do a 'deep' cleaning at the end of each season. Got to hand it to Beretta 390 autos, they can go a long way under some difficult conditions!
