Hello, this is my first post. A couple years back, I bought what I thought was a six inch shroud barrel and nut for my 15-2VH, because I wanted a shroud without the full underlug. I used my original barrel with the new to me shroud. Recently, I pulled out the old barrel to sell it as a combo with my original heavy shroud. I wanted to set it up on my gun to make sure it all worked together, which was good, because it didmn't. I then noticed the two barrels were not the same length, and the one I had purchased was actually five and three quarters inches, not six. Does anyone know what the deal is with this barrel? It looks pretty much like the other barrel, just shorter. Thanks for any info.
