Yes, a friend of mine was thinking about a competition/hunting rifle and when my recomendations were centered on Ruger and Remington he said that he always wanted to have an M14. We poped a Springfield Armory website and I saw the M-6. I must say I really like it. Since I never fired or handled one my impressions are based purly on pictures and specs. The simple mods that were done to it on the pages that you supplied link to seem to make sense and make M-6 more user friendly. But I just happen to like my Ruger 10/22. With minor adjustments and some investment I made it into very accurate and all around weapon. It may not be packing the punch of big assault rifles but the key here is survival not war. I rather be interested in survival by killing small game rather than big game. Still 22 caliber packs enough punch to be a pretty effective within 50-75 yards. Anyway since I live in NYC it doesn't matter what I have, there is no way I can pack on me or carry anything in my car on daily just in case bases. Even if it would be legal it is still far too dangerous. In case of real survival situation/doom's day I would have to get home first, grab my car and at that point if neccesary I will be able to take with me everything I want.
