I picked this book up to view any modifications or add-ons for my own AR-7. The info here is somewhat out of date (of course, it was printed in 1990), but I still found it useful in knowing what I could expect to find out there. Most of the diagrams in the book, in my opinion, would require some gunsmithing experience. The are several pages of photos, and all of these where great.
If you are one of the few to have an actual AR-7 this is invaluable information. Just remember do this unless you get a tax stamp for the BATF, unless of course the zombies are now in control and the government no longer exist. but otherwise stay legal!
"AR-7 Advanced Weapons System"- give me a break. The AR-7 was a cheap semi-auto .22 survival rifle developed by Eugene Stoner back in the late 50's for the Air Force. The blow-back action was inheritantly prone to jamming. My own weapon would jam if you oiled it too much, oiled it too little- or just looked at it cross-eyed. In a survival situation I would MUCH rather have a reliable bolt action, or even single shot, than a semi-auto that is going to jam at least once with every clip of ammo.As for it being an "Exotic Weapons System", no matter what you do with it it will still be a .22LR plinker. Even if you alter it to selective fire as the book shows, all you have is a cheap zip gun- which by the way is highly illegal even if it was worth the effort. Dressing up a rifle with military accessories such as a skeleton stock, flash supressor, and pistol grip isn't going to make it more effective. It is like putting several thousand dollars of flashy junk on a Ford pick-up- in the end you've still got a Ford.If you have a real need for an assault rifle, then get a real assault rifle- something dependable. If you need a survival gun then get something reliable (and a .410 is much more useful in filling the pot.) If you just want something cool to plink with then get one of the look-alike .22LR M-16 copies. but don't waste your time and money with this.
