Hi gang, I bought a new 930 SPX on the 7/1/16...really nice gun. Black furniture and tan paint job. I took it home and first thing I always do is a basic field stripping to clean any cosmoline or thick oil out of it so when I shoot for the first time I can diagnosis any problems easier and rule out one potential problem right off the bat.
I go to reassemble and guess what? The barrel will not slide all the way back into the receiver. It's being hung up somewhere in the gas piston area. I remove the gas piston and look inside the gas chamber area and the is a spring that has popped out on one side from the area of the gas chamber that holds the large blue spring. Imagine that...seems like some of you other fellows here have had the same problem also.
Being a gunsmith for about 16 years I happen to have a large assortment of tools on hand. I wasn't able to slip the spring back in place as things where so, I grab this...
This removes nuts off of shotgun forends as well as the nut that captures the gas spring. So once the giant blue gas spring is out you can see a spacer which has a recess cut out of the inner side surface. Sitting there is the offending spring which sits inside of that spacer. A simple push and the spring within the spacer is back where it should be...
Keep in mind the spacer has a flat side and a tapered side....the correct orientation is flat side in first, tapered side against the end of the blue spring...
Something else to consider as well is that spacer needs to be lined up even all the way around with the blue spring when reinstalling with that handy dandy forend tool. If the spacer is not installed centered all the way around when installing the blue spring the barrel will not sit all the way down flush into the receiver because the mag tube will be obstructed while trying to go through the gas port/gas piston section of the barrel. Hope this helps...
Time to reinstall the spacer, gas spring and gas spring nut: approximately 15 minutes.
