[ame="https://www.youtube.com/watch?v=OcKE4zNSgq0"]https://www.youtube.com/watch?v=OcKE4zNSgq0[/ame] 1st post here. I was going to buy a Beretta Storm Carbine when a friend suggested this set up for a Hi-Point carbine. He showed me this video. I want to build that gun. Can all of you help me with the following? What rail does he have on top and where can I buy it? How do I attach the top rail? What bottom rail does he have and where can I buy it? How do I attach the bottom rail? I plan on buying my first Hi-Point carbine. I know that he has an ATI stock and Magpul sights. Is there anything I should be aware of before purchasing these products and altering my Hi-Point carbine. They look like they are a ton of fun to shoot? BTW - where is the best source to buy magazines for it? Thanks for all your help!
