I hear you. Back when I got mine, it was the only plastic gun that anyone had ever seen, or thought about. I spent my days telling detractors (there were more than a few over the years) that it merely represented the way of the future. As a twelve year old I predicted that there would come a day when plastic would be common on guns. I guess I was one of the pioneer plastic gun owners.I was enamored by the Nylon 66 back in the day but, quite frankly, I couldn't bring myself to buy a "plastic" gun. Heck, back then I thought my Crosman PowerMaster BB gun was pretty cool and it was built like a tank but the thought of shooting a real gun made of plastic just didn't appeal to me back then.
Maybe other manufacturer's thought they couldn't compete with Remington's Nylon 66 because it had such a cult following.
When I came of age to buy my own rifle I bought a Ruger 10/22. I've seen a few Nylon 66's in my local gun shop and looked at a couple but I just can't get myself to buy one.
