Hi, had an issue with my V3. While shooting 5-stand triples, the gun wouldn't cycle. This sucked because I was on fire before it happened. Couldn't get the bolt to come all the way forward. Couldn't get the shell to go into the mag tube. I would eject the shell, put a new one in, and the bolt wouldn't go forward. So I ended up fininsihing the remaining rounds with a friends 1100.
Got it home and a Piston Stop Plate Screw came out and got in the bolt guide which wouldn't let the bolt go forward. I have about 800/900 rounds thru this gun and have cleaned it a few times, I have never checked if these screws were loose. See picture below.
So I have emailed Remington, asked for a couple of screws because I can't find them round here. They are 6/40x.25 cap screws. I can only find them at 3/8 and that's too long.
I will clean the threads out and then add a small amount of blue loctite on these threads when Remington sends me some. I will check these every time I clean it from now on. http://www.shotgunworld.com/bbs/cpg1410/displayimage.php?pos=-21854
