Hello,
I am a first time Mossberg owner, and it only felt right to join this forum for information and community, especially in light of the tragedy which has befallen me (comfort me, great ones)! It is unfortunate that my first post involves an issue, but hopefully the abundant community knowledge will prevail in the face of bad luck.
The gun: 590A1 SPX
The problem: After receiving the gun last month, I anxiously went to the range to teach a few paper targets a lesson (after a sufficient cleaning and inspection of the internals, of course). First operation involved a cheap buckshot load, perhaps 15 rounds. No issues at that point, but the length of pull was a bit too long, so I felt it in my shoulder the next day. A week later, I added the Magpul M-Lok forend in lieu of the standard corncob, and the Magpul SGA stock as well. I took the gun to the range that day, and as I was cycling the action it began to feel stiffer. Suddenly when I pushed the slide forward after a shot, the action tube nut and grip slid clean off the assembly. I had to take the whole gun apart and re-tighten the nut and Magpul spacer.
Not so bad. My range buddy suggested that I put some Lock-Tite on the threads to make sure it didn't screw lose during operation. I applied some Lock-Tite Blue, thinking this would be the more gentle and non-permanent option. I tightened the nut down, not exceedingly tight, but I made it quite snug with the tool Magpul provided.
I took the gun out with me last week for some recreational shooting on a nearby mountain. After about 35 rounds of target load, the gun action began feeling stiff again. I checked the action nut but it still felt secure, so I figured maybe my lubricant was evaporating from heat. I fired a couple more shots and the nut and slide unexpectedly popped off again. But this time, the result was more gruesome:
As you can see, the threading almost completely detached from the action tube, and was badly warped. I have never seen or heard of this happening to any shotgun, so I was completely shocked when I saw this, and totally bummed. Although in theory this does not prevent the gun from operating, I consider this to be a critical failure of a key component. If it happened to someone when they were in a life or death situation, this would most likely lead to the latter.
Now thankfully Mossberg's wonderful service reps offered to ship me a new component under warranty, but the question still remains: what caused this failure?
My thinking is that either the component was simply a pot metal goof (somewhat forgivable) or some kind of tolerance issue with the Magpul forearm (less forgivable). I'm not sure what the best way to diagnose the problem would be, but I sure as heck don't want it to happen again. Thoughts? Questions?
