MP5 build on an SW5 receiver, NF461 3type stainless (melonite) bolt head, stainless barrel, Fabarms tri rail handgaurd, This picture was when i was making it. It now has a fake suppressor attached and a telescoping buttstock, much nicer than the folding "k" stock that it was pictured with. Right now it is out getting painted and laser engraved. comes with 2x30 round magazines. This was made with the some of the best parts available. I've done plenty of research and wouldn't mind explaining why this one is great.
