I am building a automag from scratch and I was woundering where I can find body rails such as the omega, benchmark, etc.. I am planning on getting the X valve to with the level 10 upgrade. How well does the level 10 work? Is the gas efficently is good? Can u get like 1200 rounds with a 68 4500? I used to have a automag with the retro valve. I was the first one to get one in california and it worked very well. I wish I never sold it. Plz tell me how u like ur level 10. thanks. I used to be on this all the time but I took 1 yr break from this, and I want to get a automag because they are really reliable. NO body in cali has a automag and I want to show everyone that automag is the best money can get!
