Hey, I bet you all like the looks of a spiral ported barrel, right? I bet you have also looked at the price tag and said, just a bit to high when you want to say, OH MY GOD THATS A FRIGGIN RIP OFF. I have the solution. DO IT YOURSELF. I just did mine, about 2 hours ago and my gun is so much more accurate and quiet. All I did was take a peice of paper, computer paper works great, and measure it our to the length of your barrel. Then wrap it around your barrel and cut it so that you have almost no overlapping paper. Then, fold your paper hamburgerwise then hotdog wise the hamburger the hotdog and so on until you have as many folds as you think neccessary. Then, unfold the paper, and put a dot on the spot where the axes meet, not in a straight line but in a diagonal, then finally wrap the the paper around the barrel and tape it. Drill a 1/8 hole(thats what I used) on each dot. This is the easiest way to custom port your barrel I have found. It increased my accuracy so much I can hardly believe I am still shooting my STOCK Point Zero. My point zero is the awesomest begginner gun I can think of, or have ever shot, so IF YOU HAVE NEVER OWNED A GUN BEFORE GET A POINT ZERO MODEL 83. I got mine for $20 BRAND NEW ON E-BAY
