if you're one of the few whose SPAS 12's won't cycle using full-power 2 3/4" rounds (not the light stuff), or you're having trouble switching from Manual to Autoloading mode and back it's probably a sign of a dirty gas system. Here's a video showing the dis-assembly and re-assembly of the gas system. Make sure to watch it in 1080P HD if you can.
I'll be shooting a few more instructional videos to round out some updates I'll be making to the site, but I'll pepper in some more shooting videos now that the weather is back to normal.
Thanks to everyone for all the support, it's going to be a great year!
