You guys are quite welcome. I literally just stumbled upon it. I was talking to my grandfather and he said I should go to this website and subscribe to the magazine. He had no clue that my carbine was a currently featured article! I'm glad you all have liked it as much as I did. I'm anxious to see what they say about the Five-seveN and the 5.7x28mm cartridge (when they get to it).
Here is the final PS90 after undergoing the SBR process. In the article I mentioned FNforum.net as a place to gather more information on 5.7 related systems. I hope it works well for you. I appreciate the education I get from places such as this (even if they start off rocky ) and if I can help the community in return I am happy to do so.
p.s. I have a neat piece coming up on the Uni-Max lasers and used the PS90 and the Five-seveN as platforms. I got an interesting photo of the beams (yes they are real and not photoshopped) and I thought you folks here would enjoy a little sneak peek too.
